Karen L. Miller, MD; Morton A. Stenchever, MD; Holly E. Richter, PhD, MD; Evelyn C. Granieri, MD, MPH, MSEd; William C. Andrews, MD, FACOG, FRCOG* Gynecologists play three roles in the health care of women aged 65 and over: surgeon,consultant and therapist for gynecologic disorders, and provider of primary and preventivehealth care. The research reviewed here addresses topics related to one or more of theseroles. Our review indicates that, as the population ages, our astounding lack of knowledgeabout caring for elderly women in these three contexts must be addressed.
The MEDLINE database was searched via PubMed. The period covered was from 1990 toMarch 21, 2001. The search was limited to English language and human subjects. Thesearch strategy combined the MeSH terms for gynecologic surgical procedures, hormonereplacement therapy, cervical cancer and cervical cancer screening, breast cancer andbreast cancer screening, ovarian cancers and ovarian cancer screening, pelvic organprolapse, and postmenopausal osteoporosis with terms for age factors, risk factors,perioperative care, perioperative complications (including the specific terms delirium,decubitus ulcer, pneumonia, and cerebrovascular accident), comorbidity, outcome, qualityof life, prognosis, recovery, length of stay, functional status, resuscitation status, and dis-charge planning. In all, 9522 items were retrieved.
The search was then narrowed to 1638 by requiring that the term age factors or variants of the word age be included in the title. During the time from March 2001 until thismonograph was completed, striking studies from the Women’s Health Initiative with un-expected results were published about hormone replacement therapy. Therefore, sectionsabout hormone replacement were updated to include the more recent information.
Topics and research questions regarding general perioperative management of elderly pa-tients are addressed in the chapter on cross-cutting issues (see Chapter 13). For this chap-ter, studies focused on gynecologic surgery were sought to determine the current state ofknowledge and to identify gaps that suggest the best direction of future research.

Few studies have been published about gynecologic surgery in elderly women. In thepublished studies, many common geriatric complications were not recognized or soughtby the investigators. For instance, none of the case series, retrospective reviews, orcase-control studies noted delirium, falls, or electrolyte imbalance. These occur commonlyin hospitalized elderly patients, and it is unlikely that they were completely absent in thepopulations described. Furthermore, all studies on the topic of gynecologic surgery gener-ally were retrospective chart reviews, and undoubtedly geriatric complications were notwell documented and therefore were not obtainable. Finally, no studies that evaluatedfunctional or quality-of-life outcomes in older women were found.
Studies were found regarding the incidence and prevalence in older populations of hysterectomy, 1–3 the prevalence in older women of surgery for pelvic organ prolapse(POP), 4 complications in elderly women of gynecologic surgery (including benign andmalignant diseases), 5–11 and preoperative evaluation of risk factors for cardiac complica-tions in older women. 12 No studies involved institutionalized elderly persons.
Annually from 1988 to 1990, 4 per 1000 women aged 65 to 74 and 2 per 1000 aged 75and over underwent hysterectomy in the United States; 2 similar rates were reported inFinland. 9 In one state, the cumulative probability of a woman’s having undergone ahysterectomy was 33% by age 55 and 43% by age 85. 1 Most hysterectomies in olderwomen were found to have been done for POP, followed by malignant disease; roughlyone third of all hysterectomies fell in each category. 1,2 Bilateral salpingo-oophorectomywas performed in 87% of abdominal and 7% of vaginal hysterectomies. 2 A woman has a10% to 11% cumulative risk to age 80 of undergoing surgery for urinary incontinence orPOP. 4,13 Morbidity and Mortality
In Finland, age was associated with mortality in 300,000 hysterectomies, not controllingfor comorbidities. 9 Six-week mortality ranged from 3 per 10,000 in the age group 40 to50 years to 209 per 10,000 in those aged 80 and over. Sixty-three percent of deaths weredue primarily to cancer, and 27% to cardiovascular events. In 66,478 Medicare patientsundergoing continence procedures, the 30-day mortality was 0.33%. 5 Mortality increasedlinearly with age, from 0.2% at age 65 to 74 to 1.6% in those aged 85 and over.
Age-specific mortality rates were not adjusted for comorbid conditions. Groups of patientswho died had higher rates of diabetes mellitus and heart failure. Age was not found to beassociated with morbidity and mortality in other studies of gynecologic surgery, 11 POPsurgery, 7 and gynecologic oncologic surgery. 10 The only prospective morbidity studyincluded all major noncardiac surgical procedures in women aged 50 or over. 8 This studyfound age to be significantly associated with a greater incidence of cardiogenic pulmonaryedema, myocardial infarction, ventricular arrhythmia, bacterial pneumonia, respiratoryfailure, and in-hospital mortality. Older patients were not found to be more likely thanyounger ones to experience neuropathy after dorsal lithotomy positioning. 6 A retrospec- tive review of postoperative fever evaluations found that older age increases the likelihoodthat the chest x-ray would “be positive” (definition not given). 14 In a retrospective analysis of 406 women undergoing elective vaginal surgery, cardiac morbidity was found to have occurred only among postmenopausal women. 12 The fourcongestive heart failures, one unstable angina, one unstable arrhythmia, and two deaths(apparently secondary to myocardial infarction) were not predicted by either the GoldmanCardiac Risk Index or the New York Heart Association functional classification of heartdisease. Only hypertension and ischemic heart disease were found to be risk factors.
Few studies have examined outcomes of gynecologic surgery in elderly women, and thesehave not evaluated typical geriatric complications. No studies have evaluated functionaloutcomes, and few have evaluated intermediate- or long-term quality-of-life changes.
Mortality risks with gynecologic surgery are low and most commonly are due to cardiacor cancer complications.
Gyn 1 (Level B): Prospective observational studies should be undertaken

observational studies should be performed to compare the risks of
gynecologic surgery that are associated with age alone and those
that are associated with comorbidities.

Gynecologists treat both anatomic and functional aspects of urogenital health and healthmaintenance. Certain well-known age-related changes are secondary to estrogen defi-ciency and are easily treated with estrogen replacement. However, age-related functionalchanges are heterogeneous, and many questions remain about their causes and therapy. Weaddress the research in POP, vulvovaginal conditions, urinary incontinence, and sexualhealth.
The surgical and nonsurgical management of POP together constitute a substantial portionof gynecologic care for older women. The exact prevalence and natural history of POP areunknown. It is the most common reason for gynecologic surgery in women aged 65 andover. Surgical repair usually consists of full vaginal reconstruction. However, vaginalobliteration with the Le Fort colpocleisis is still a useful alternative to major surgery forsome frail elderly women. There is also a resurgence in conservative therapy using pes-saries, as the older population grows and the imperfection of long-term surgical resultsbecomes more evident.
Quality of Data
Epidemiology. Data regarding the prevalence of POP requiring surgery are included in the
section, above, on gynecologic surgery. Prevalence data for POP apart from surgical cor-
rection are few. One descriptive study using routine gynecologic care patients included 66
women aged 60 to 82. 15 One paper retrospectively reviewed admissions to a long-term-care facility. 16 Risk factors for POP that requires surgery were evaluated in a case-controlstudy; 17 the risk factors for symptomatic pelvic floor dysfunction (including POP) wereevaluated in a study using population-based cross-sectional interview data; 13 and riskfactors for urinary incontinence or POP that requires surgery were assessed through aKaiser Permanente database review. 4 Complications. Hydronephrosis as a complication of POP has been reported in two retro-
spective case series. 18,19 No studies were found about other well-known complications,
abrasions, or urinary retention due to a large cystocele.
Nonsurgical Management. We found no data on the natural history of POP. Articles
about pessaries are based mostly on expert opinion, and some are case reports. One retro-
spective chart review reported indications, continuation, and complications. 20
Surgical Management. A retrospective chart review evaluated age and voiding function
following POP surgery. 21 One small prospective randomized study evaluated the effect of
local estrogen prior to reconstructive vaginal surgery. 22 A case series compared the Le
Fort procedure in medically compromised women to pelvic reconstruction in healthier
women. 23 Some case series described major comorbidities, postoperative complications,
and outcomes, 24,25 including one of POP repair under local anesthesia. 26 Several case
series describing technique and results included younger and older women but rarely
stratified them by age, and these studies are therefore not reviewed here.
Epidemiology. In one study of older patients receiving routine gynecologic care, 50% to
60% were found to have stage II POP; stage III prolapse was present in 9% of the women
aged 60 to 69 and 21% of the women aged 70 and over. 15 A review of long-term-care
facility admissions found 25% of the women to have POP, 11% of which was beyond the
introitus. 16 Age was found to be an independent risk factor for symptomatic pelvic floor
dysfunction (including POP) in a large Australian household survey. 13 A Kaiser database
study also found age to be an independent risk factor for pelvic floor surgery. 4 The effect
of age was not evaluated in a case-control study of women aged 34 to 75. 17 Other risk
factors that have been identified are parity, 4,13,17 body mass index, 4,13 and chronic lung
disease or coughing. 4,13 Forceps delivery was found to be a risk factor in an
epidemiologic survey, 13 but not a case-control study. 17 There was no difference in POP
prevalence with a history of cesarean section or of nonoperative vaginal delivery, 13,17
once the number of vaginal deliveries was controlled for. 17 It must be noted that these
studies evaluated the range of younger and older women. No studies evaluated the risk
factors just for the older women.
Complications. In one study, 11% of 189 women undergoing POP surgery were found to
have mild hydronephrosis and 4% had severe hydronephrosis. 18 Women with
hydronephrosis were older (mean age 68 Ϯ 10) than those without (mean age 61 Ϯ 11).
However, in multivariable logistic regression, only uterine (rather than anterior vaginal
wall) prolapse was found to be statistically associated with hydronephrosis. Age was not
associated. Among 323 POP surgical patients at the Cleveland Clinic who had preopera-
tive imaging, 8% were found to have had hydronephrosis—4% mild, 3% moderate, and
1% severe. 19 Mean age was 75 in women with and 67 in women without hydronephrosis(P Ͻ .001). Uterine prolapse was more strongly associated than vaginal vault prolapsewith hydronephrosis, even after adjusting for age and degree of prolapse. The two patientswith renal insufficiency both had complete procidentia.
Nonsurgical Management. No studies compared types of pessaries. In a case series that
preferentially placed Gellhorn pessaries, 96 of 101 women used a Gellhorn. 20 Of five
women who could not retain a Gellhorn because of poor perineal support, four used a ring
pessary and one a cube. Of 50 patients who continued pessary use 2 months to 5 years, 45
removed and reinserted the pessaries themselves. Forty percent discontinued pessary use
because of inadequate symptom relief or inconvenience, but the authors did not further
quantify this.
Surgical Management. A retrospective review of 23 women undergoing POP surgery did
not find age to correlate with duration of catheterization (independently of estrogen sta-
tus). 21 Among 43 women who underwent prolapse repair, preoperative vaginal estradiol,
compared with placebo, was not found to influence the 3-year relapse rate, although
bacteriuria was lower in the immediate postoperative period. 22 Twenty-one medically
compromised women who underwent Le Fort procedures, mean age 82 years, and 42
women who had vaginal reconstruction, mean age 67, had a similar number of postopera-
tive complications, including one cardiac arrhythmia and three urinary tract infections in
each group. 23 Both groups had 90% to 95% long-term success. In a series of 33 women
treated with colpocleises, mean age 78, postoperative complications included congestive
heart failure (2) and pneumonia (1). 24 One woman required a second repair. Postoperative
complications occurred in 29% of 38 women in another Le Fort procedure case series,
including cardiac (11%), respiratory (5%), and urinary (13%) complications. 25 Local an-
esthesia was used successfully for vaginal POP repair in 20 women, mean age 80 years,
including anterior and posterior colporrhaphy, enterocele repair, and Le Fort
colpocleisis. 26 The only major complication was venous thrombosis. Pyometra followed a
re-do Le Fort colpocleisis in a 92-year-old woman. 27
Few data exist on the incidence of or risk factors for POP, with the exception of cases thatundergo surgery. The benefit of estrogen prior to POP repair, if any, is unknown. Olderage, parity, and operative vaginal delivery are risk factors for POP surgery. The risks ofpregnancy alone, regardless of route of delivery, or of the number of vaginal deliveries arenot clear. In women with POP, age may be a risk factor for the development ofhydronephrosis, but uterine procidentia confers the most risk. Pessary management isvirtually all by clinical experience, usually passed on by tradition or invented by indi-vidual physicians.

The nature of atrophic postmenopausal vulvovaginal changes is reasonably well estab-lished, but the contributions to these changes of aging, factors common in aging, andhypoestrinism are unclear. The pathophysiology of vaginal and, to a lesser extent, vulvardisorders is a unique combination of hormonal, dermatologic, microbiologic, structuralsupportive, environmental, neurologic, and psychologic factors. Vulvar pathophysiology isprimarily dermatologic, with strong environmental influences and less well understoodhormonal components.
The lower vagina, vulva, urethra, and bladder trigone have a common embryologic origin, the urogenital sinus, and are estrogen-responsive tissues. Dermatologic symptoms,vaginal discharge, dyspareunia, irritative voiding symptoms, and urinary tract infectionsmay all be a consequence of prolonged hypoestrinism. Data regarding the prevalence ofsymptomatic vulvovaginal changes with aging are divergent and difficult to obtain withoutthe inclusion of urologic symptoms such as dysuria, frequency, urgency, and urge inconti-nence.
Unclear factors associated with aging, hypoestrinism, or local environment increase vulvar susceptibility to dermatologic disorders, including lichen sclerosus, squamoushyperplasia, and neoplasia.
Quality of Studies
Relevant studies of urogenital symptoms include community-based observationalsurveys 28–32 and a case series of menopause clinic visits. 33 A meta-analysis summarizedestrogen therapy trials, 34 an uncontrolled trial evaluated estrogen therapy, 35 and an obser-vational study reported associations with sexual activity. 36 Vulvar cancer data are takenfrom a population-based study and case series. 37–39 Review articles and one randomizedcontrolled trial are cited regarding vulvar dermatoses and neoplasia. 40–43 Results
Two large surveys gathered data through personal interviews. 28,29 In one, urogenitalsymptoms were found to be prevalent in 30% of 3000 European women aged 55 to 75. 29Eleven percent were found to have vaginal itch or burning, of whom 41% had a moderateproblem and 17% a severe one. Of women aged 65 to 74, 9% reported having urinaryfrequency, 6% urinary incontinence, and 4% vaginal burning or itch. Of 2045 Britishwomen aged 55 to over 85 years interviewed in their homes, 49% reported havingurogenital symptoms some time since menopause, and 31% within the past 2 years. 28Vaginal itching occurred in 11%, vaginal dryness in 8%, dyspareunia in 2%, and irritativevoiding symptoms in 16%. Only 27% were sexually active. Of 900 61-year-old Swedishquestionnaire respondents, 38% reported vaginal dryness and dyspareunia, and 15% re-ported itch, discharge, and “smarting” pain. 32 Among 850 randomly selectedpostmenopausal Dutch women, 23% reported vaginal itching and 16% dyspareunia. 31Clinically assessed vulvovaginal atrophy was evident in 34% of women evaluated in amenopause clinic. 33 Approximately 25% of the sexually active women had dyspareuniasecondary to vulvovaginal pain.
A meta-analysis of 10 randomized controlled trials and 68 other relevant articles con- cerning older women, mean ages ranging from 54 to 72, showed that estrogen relieves urogenital atrophy symptoms, including vaginal dryness, itching, burning, and discharge;dyspareunia; urinary frequency; nocturia; urgency; dysuria; and recurrent urinary tractinfections. 34 All administration routes were found to be effective. Intramuscular estrogenhas been found to improve irritative voiding symptoms, as well as urge incontinence, in84% to 94% of 24 postmenopausal women, mean age 70. 35 A cross-sectional analysis ofwomen with a mean age of 57 found fewer symptoms and less vaginal atrophy in thosewho continued regular sexual activity through menopause than in those who did not. 36 The incidence of vulvar dermatoses is unknown. 41,44 Lichen sclerosus may affect all age groups, but it seems to occur most commonly at times of low sex hormone output, inboth the pediatric and postmenopausal ages. 44 Incidence is highest in the fifth and sixthdecades in women. The incidence among dermatology referrals ranges from 1 in 300 to 1in 1000, but the condition is more commonly seen by gynecologists who care forpostmenopausal women. Squamous cell cancer occurs in 4% to 5% of known cases, butthe contribution of lichen sclerosus to neoplasia is unknown. 44 Topical testosterone andprogesterone are time-honored therapies, but their effectiveness may be no better than thatof the carrier used without the steroid. 42 Topical petrolatum alone has been found torelieve symptoms in 75% of patients aged 35 to 83. 45 High- and medium-potency topicalcorticosteroids are the treatments of choice. 44 The incidence of vulvar cancer rises sharply at age 60 until at least the ninth decade, reaching 0.02 to 0.03 in the ninth decade, 37,38 although melanoma may peak in the sev-enth decade. 39 Summary
Most urogenital symptoms are related to hypoestrinism and are reversed with estrogentherapy. Symptoms are multifactorial, relating also to urinary tract dysfunction, microbialinfluences, dermatoses, and local environment. Aging-specific symptoms apart from endo-crine failure are unclear. The incidence of vulvar cancer and non-neoplastic dermatosesrises with age. Susceptibility factors are poorly understood. The contributions of endocrinefailure to these disorders are unknown.

tionalized populations.

Urinary incontinence in elderly persons is covered in the chapter on geriatric urology (seeChapter 10).
Two areas are of interest in older women’s sexuality: sexual function and sexual dysfunc-tion. Continued sexual activity into advanced age has been well documented. The fact thatno diagnostic codes exist for female sexual dysfunction except psychologic disorders anddyspareunia bespeaks our remarkable ignorance, but medical knowledge of thepathophysiology of female sexual dysfunction is slowly expanding. The study of sexualdysfunction in elderly women is probably even more complex than that in younger womenbecause of numerous relevant health and medication interactions, because of longer andmore complex relationship issues, and because insufficient information is available aboutnorms of physical response, as well as about the effects of androgens and estrogens (otherthan for urogenital atrophy).
Quality of Studies
Several questionnaires of varying scope and quality have been reported about sexual func-tion and dysfunction in aging and are summarized in recent articles. 29,46–50 Demographicdata are limited by convenience samples and low survey response rates. Community-basedsurveys have also been done. 46,50 One questionnaire was obtained before and after athree-part instructional program. 51 Masters and Johnson’s 1966 work remains the defini-tive study of physiologic age-related changes in the sexual response cycle. 52 Most sexualdysfunction studies concern only the treatment of atrophic vaginitis. 47,50 Results
Sexuality remains an important part of many older women’s lives. One survey found that30% of women aged 80 to 102 were sexually active, 53 as have other population–basedstudies. 29 Nonintercourse intimate activities increase in importance for men and maintain or increase in importance for women. 51 Many sexually “inactive” women continue to beinterested in sexual relations and masturbation. 46,49,51 Advanced age is inversely associ-ated with sexual activity in men but may not affect women when other factors, includingpartner status, are controlled for. 46 Heterosexual activity correlates with marital sta-tus 46,49 and is most often limited by lack of a partner or by male sexual dysfunction. 50,51However, in one population survey, satisfaction with sexual activity or lack of activity wasnot found to correlate with marital status. 46 Age was associated with both activity andsatisfaction in men but not in women. Specific medical conditions often but not invariablycorrelate with less activity or satisfaction, but overall health status is importantuniformly. 46,47,49,50,54–56 Age-related changes in the sexual response cycle, comparing pre- with postmenopausal women, include decreased skin flush, muscle tension, reaction time, secretions, vaginallubrication and expansion, congestion, and number of contractions with orgasm. 52Dyspareunia and decreased lubrication secondary to urogenital atrophy are the most com-mon sexual dysfunction findings. 29,47,50,53,57 Urinary incontinence and POP also nega-tively impact sexual activity, 50 but not necessarily satisfaction. 58 However, little isknown about specific disorders of desire, arousal, and orgasm in older women. Animalstudies show that fibrosis of erectile tissue associated with cardiovascular disease may belinked with sexual arousal disorders in women, as has been found in men. 59,60 The sexualeffects of a decline in androgens with age 61 or of hormone replacement therapy (HRT) 62have not been evaluated in the geriatric age group.
Regular sexual activity of elderly women is often limited by lack of a partner. However,given the documented level of interest, it is likely that medicine could still make a positiveimpact on elderly women’s sexual vitality and therefore on their sense of well-being.
Research is sparse and needed in virtually every aspect of this field.
Gyn 39 (Level B): Current investigations into the diverse causes of
younger women’s sexual dysfunction and its pathophysiology and
management should be extended to include older women.

Gyn 40 (Level B): Observational studies are needed to determine the
medication side effects that adversely affect specific aspects of
sexual function in older women.

Gyn 41 (Level B): Observational studies are needed to define the adverse
effects on older women’s sexuality of specific medical conditions.
Gyn 42 (Level B): Dose-effect cohort studies of optimal dosage, fre-
quency, and route of administration are needed to learn more about
androgen replacement in elderly women.

Gyn 43 (Level A): Clinical trials are needed to determine the ability of
androgen replacement in older women to enhance outcomes, in-
cluding specific aspects of sexual function (eg, libido, orgasmic

Gyn 44 (Level A): Randomized controlled trials should be performed to
determine whether oral estrogen replacement adversely affects
sexual function in older women, presumably by decreasing free
testosterone levels, and whether this is avoided by the use of
transdermal estrogen.

Gyn 45 (Level D): The emotional and physical components of the sexual
response cycle in the older woman should be observed and defined
in light of new and more sophisticated information about female

Gyn 46 (Level D): Pilot studies should be performed to determine educa-
tional strategies for partners of cognitively impaired patients that
enable them to deal with sexuality issues.

Gyn 47 (Level C): Clinical trials should be undertaken to improve the
treatment of dyspareunia secondary to urogenital atrophy in
women unable to use estrogen products.

The benefits derived from routine gynecologic examination and subsequent care in bothhealthy and frail older women are unknown. Pelvic examination may prompt evaluationand treatment of several disorders, as well as provide an opportunity for cancer screening.
However, little is known about the impact of gynecologic examination in specific popula-tions, such as institutionalized, homebound, and frail older women. Does gynecologicevaluation lead to the detection and management of issues that impact quality of life thatwould otherwise be ignored or minimized by the community-dwelling patient? How canthe additional costs to the primary care provider of routine gynecologic examination beadequately reimbursed? Essentially no studies answer these questions. This chapter sum-marizes the topics most reported in gynecologic care for the well older woman: cervicaland breast cancer screening.
Cervical cancer screening with Papanicolaou (Pap) smears, initiated in 1943, has neverbeen evaluated in a randomized controlled trial. However, the observational evidence isoverwhelming that regular Pap smear screening reduces the incidence and mortality ofinvasive cervical cancer. The incidence of invasive cervical cancer is lower in womenaged 65 and over, but mortality is higher, largely because stage at the time of diagnosis ismore advanced. 63 Therefore, recommendations to discontinue screening in older agegroups must be viewed with caution.
Quality of Studies
Epidemiology of Screening. Epidemiologic data regarding the prevalence of screening
and of the incidence and prevalence of abnormalities in older women are obtained prima-
rily from observational retrospective reviews of health databases, 64–71 cross-sectional and
retrospective reviews, 70,72–79 and one prospective cohort study. 80 In addition, we found
three screening intervention studies targeting or reporting on elderly women, 81–83 one
prospective cohort study within a randomized controlled trial to determine the positivepredictive value (PPV) of Pap smears, 84 and one prospective cohort study to evaluate theeffect of Pap smears on mortality. 85 Two studies evaluate the influence of HRT on Papsmear abnormalities, one of them a prospective cohort nested in a randomized clinical trialof HRT and cardiovascular disease, 84 and one, a retrospective case analysis. 69 Screening Improvement. One survey and a quasi-experimental study evaluated interven-
tions to increase screening in elderly women. 81,82 Screening improvement trials with
low-income women aged 40 and over were also found: 83 Mexican American and black
women aged 40 to 70 years, 86 Cambodian women aged 50 years and over, 87and black
American women aged 40 and over. 88
Screening Cost-effectiveness. The cost-effectiveness of screening for cervical cancer was
calculated in a decision analysis applied to hypothetical 65-year-old women 89 and by
using a retrospective chart review in an urban municipal hospital. 90
Consensus Recommendations. The recommendations of national organizations for cervi-
cal cancer screening in older women are based primarily on expert opinion. 91–94
Epidemiology of Screening. Age was found to be inversely associated with having had a
Pap smear in a retrospective database analysis, 71 a cross-sectional survey, 79 and a pro-
spective cohort study. 80 However, in another study, of economically disadvantaged
women aged 50 and over, age was not found to be a correlate of having had cervical
cancer screening. 95 In this group, income and access to a telephone were strong correlates
of cervical cancer screening. Low rates of screening may also occur more often in some
ethnic minorities, as well as among women with less education and a lower socioeco-
nomic status. 67,70,71,75–77,79,80 In an analysis of data from the Iowa Behavioral Risk Factor
Surveillance System (BRFSS) and Iowa’s Surveillance, Epidemiology, and End Results
(SEER) study, barriers to screening were found to include rurality and limitations in ac-
tivities of daily living. 96
In a retrospective review of 96 abnormal Pap smears and their outcomes in women aged 55 and older, the prevalence of atypical cells of undetermined significance (ASCUS) wasfound to be 2%, lower than the 4% to 6% found in younger women. 69 The likelihood ofpathology was also found to be lower: about 15% low-grade squamous intraepitheliallesion in the older women but 25% to 33% in the younger women. However, about 5% ofASCUS smears resulted in a diagnosis of cancer, including cervical, endometrial, andovarian. An observational study of 1542 women aged 65 and over found a 1.5% preva-lence of abnormal Pap smears. 64 Seventy-five percent of the women had not had regularPap smear screening, and 25% had never been screened. Age, race, prior screening, andgynecologic symptoms failed to predict Pap smear abnormality. Two studies have foundan association between HRT and abnormal (ASCUS) Pap smears. 69,84 These studies donot clarify whether a more active squamocolumnar junction due to hormonal influencesplaces a woman at greater risk for true abnormalities or artifactual abnormalities, orwhether a more accessible transition zone allows improved screening.
In a prospective cohort study nested within the Heart and Estrogen/progestin Replace- ment Study (HERS) randomized controlled trial, the incidence of new cytologic abnor-malities within 2 years of a normal Pap smear was 23 per 1000 woman-years, with a PPV for dysplasia of 1%. 84 Centers for Disease Control and Prevention 1991–1998 datashowed that the incidence of high-grade Pap smear abnormalities within 3 years of onenormal Pap smear declined from 66 per 10,000 women aged 30 or younger to 10 per10,000 women aged 65 or older. 97 A review of cancer deaths in women in Australia aged 50 or over found that 70% could have been avoided by appropriate screening. 78 In the women aged 50 to 74, 67% hadnever been screened, and none of those aged 75 and over had had a Pap smear. A retro-spective case analysis in 1989–1990 of 798 Scottish women with cervical intraepithelialneoplasia and cervical cancer found that the 26 aged 50 or over with microinvasive orinvasive cancer had not been screened adequately. 72 Greater age was associated with alater stage at diagnosis of cancer 74,98 and a higher risk of death within 6 months ofdiagnosis 73 in cross-sectional epidemiologic studies using cancer registries. In womenaged 21 to 96 years, each additional year of life conferred 3% increased odds of late-stagediagnosis. 74 Independent covariates were being unmarried and uninsured, but not race,education, income level, smoking status, medical comorbidity, or urban residence. In aSwedish population, the incidence of cervical cancer was only 3 per 100,000 amongwomen aged 70 or over who had at least one normal Pap smear in the previous 10years. 85 Screening Improvement. Elderly black women improved their screening rates following
a survey and when offered screening by a nurse practitioner. 81,82 Having lay health advi-
sors interview low-income women was found to be effective “across age and insurance
strata.” 83 Other trials to improve screening rates included few elderly subjects.
Screening Cost-effectiveness. The cost per year of life saved in hypothetical 65-year-old
women ranged from $2254 for triennial to $7345 for annual screening. 89 Triennial screen-
ing reduced cervical cancer mortality by 74%. It was calculated from a chart review that
100 Pap smears in low-income elderly women could save $5907 and 3.7 years of life. 90
Consensus Recommendations. Consensus recommendations for frequency of Pap smears
in older women vary from discontinuation after age 65 94 to continued screening until age
70 93,99 to no upper age limit. 91,92 The most commonly recommended screening interval
is 3 years.
Posthysterectomy. Pap smears have little or no utility in women who have had a total
hysterectomy (corpus and cervix uteri) for benign disease. 100,101 The American College
of Obstetrics and Gynecology recommends “periodic” vaginal cuff Pap smears in women
with any risk factors for cervical cancer or any endometrial, vaginal, or vulvar
neoplasia. 91 Several factors speak for documenting at least one normal vaginal Pap smear
in elderly women and possibly continuing “periodic” vaginal Pap smears:
Ⅲ Most practitioners do not take a full past sexual history for older women.
Ⅲ Data regarding the relevance of known risk factors (human papilloma virus, sexual practices) to vaginal intraepithelial neoplasia in older women are lacking.
Ⅲ Data regarding the relevance of a remote operation for gynecologic cancer to vaginal Pap smears in elderly women are lacking.
Ⅲ Elderly women may not know why, and occasionally if, a hysterectomy was per- formed, and whether the hysterectomy was total (corpus et cervix uteri) or subtotal(corpus uteri).
Screening rates are low among women aged 65 or over, particularly those who are older,unmarried, and with poor medical financial coverage. In these women, the death rate fromcervical cancer is much higher than in screened women, owing in large part to diagnosis ata more advanced stage. Extending the screening interval beyond 3 years leads to a greaterincidence of abnormal Pap smears. Studies of Pap smear benefits have examined primarilydisease incidence and mortality, rather than quality-of-life and functional issues, and thushave not included important outcomes relevant to geriatric care. Interventions to promotecervical cancer screening in elderly women are effective.
Gyn 48 (Level B): Cost analysis should be performed to measure the
comprehensive costs to the primary care provider of obtaining a
Pap smear in an elderly woman and to compare these with current
Medicare reimbursement.

Gyn 49 (Level B): As the baby boomers age, observational studies are
needed to determine the cervical cancer incidence in a changing
elderly population with different sexual risk factors and to compare
this with previous incidence rates.

Gyn 50 (Level B): Observational studies are needed to delineate all fac-
tors associated with the increased mortality rate of cervical cancer
among elderly women.

Gyn 51 (Level A): Clinical trials should be performed to determine
whether strategies to improve cervical cancer screening in impover-

cer mortality, and which strategies are most cost-effective.

Gyn 52 (Level D): Observational studies should be performed to deter-
mine the relationship of well-established risk factors (eg, multiple
sex partners, history of human papilloma virus, cervical dysplasia,
smoking, medical or viral immune suppression) to the incidence of
cervical or vaginal cancer in elderly women.

Gyn 53 (Level D): Observational studies should be performed to deter-
mine whether early detection of cervical neoplasia confers
quality-of-life benefits on frail elderly women.

Almost half of all breast cancers occur in women aged 65 and over. The average lifeexpectancy of elderly women is usually underestimated. These facts imply that there is asubstantial benefit to screening mammography for older women. However, few data existto support or refute this presumption. Far fewer elderly than young women have been included in screening trials. Most studies use longevity as an outcome, rather than qualityof life or burden of disease, which are of greater concern to older persons.
Quality of Studies
Only two randomized controlled trials of mammography, conducted in Sweden, includedwomen to age 74 at entry. 102,103 Systematic reviews presented results from five Swedishtrials, 104 seven randomized controlled trials and six case-control studies, 105 and thirteenrandomized controlled trials with 7 to 9 years of follow-up. 106 Case-control studies fromthe Netherlands reported mammography benefit in women aged 65 and over. 107,108 Ret-rospective cohort and cross-sectional studies reported the impact of mammography oncancer incidence and stage at diagnosis in women aged 65 and over. 109–114 Studies havelooked at the impact of age on the PPV, 108,110,111,115,116 recall rate, 110 cost-effec-tiveness, 117–119 and sensitivity among estrogen replacement therapy (ERT) users. 120 Ret-rospective database reviews have evaluated factors associated with screeningprevalence. 96,121–125 Results
Six of eight randomized controlled mammography trials demonstrated a 20% to 30%decline in mortality for women aged 50 to 70. 103 In 5 to 13 years, Swedish mam-mography trials demonstrated reduced mortality among women aged 50 to 69 (relativerisk or RR 0.71), but no effect was seen in women aged 70 to 74. 104 The one trialincluding these older women was closed after only two screenings. A meta-analysis ofseven randomized controlled trials including women to age 74 and six case-control studiesincluding women to age 70 demonstrated that screening mammography reduces mortality(RR 0.70, 95% confidence interval or CI = 0.63 to 0.78 and RR 0.32, 95% CI = 0.28 to0.38, respectively). 105 The true benefit may have been higher in the randomized con-trolled trials, which were confounded by low compliance rates in the treatment groups(50% to 80%) and prescreening in the control groups (20% to 30%). A meta-analysis ofrandomized controlled trials found lower mortality in screened women aged 50 to 74 yearsafter 7 to 9 years of follow-up regardless of the number of mammographic views perscreen, the screening interval, or the number of years of follow-up. 106 Case-control stud-ies using one mammographic view every 2 years found lower mortality in women agedless than 65 years and 65 to 74 years (one with and one without statistical significance),but no demonstrable benefit in women aged 75 and over. 107,108 Retrospective cohort andcross-sectional studies have found among screened women aged 65 and over less meta-static disease and a lower stage at diagnosis. 109–114 One study in women aged 85 and overfound that point estimates were similar but statistical significance was lost. 112 The PPV of mammography increased with age in most, 110,111,115,116 but not all 108 studies. ERT has been found to have less negative impact on mammogram sensitivity inwomen aged 70 and older than in those who are younger. 120 Studies have found greatestcost-effectiveness in women with high bone mineral density (BMD) 117 and in womenaged 50 to 79 118 and 50 to 69. 119 Database reviews have shown costs (ie, Medicarecopayment), functional activity limitations, advanced age, and rurality to be associatedwith less mammographic screening. 96,121–125 Summary
Regular mammography benefits women to age 74 and probably to age 85, lowering breastcancer morbidity and mortality. Studies that have shown no statistical benefit in womenaged 70 and over or 74 and over have evaluated only mortality. Studies looking at theburden of disease and stage at diagnosis have shown benefit to age 85 and perhaps be-yond. Financial and functional barriers reduce screening.
Gyn 54 (Level B): The results of existing and future mammography
studies should be stratified by age, even when power is low, to fa-
cilitate systematic reviews of results in older women.

to hormone replacement therapy increases breast cancer mortality
or burden of disease in older women.

Gyn 60 (Level D): The concurrence and variability of mammogram in-

Estrogen is prescribed to elderly women as a preventive medication, not for menopausalsymptoms. Because of the number of potential ERT candidates and the number of poten-tially affected organ systems, the decision to initiate or continue ERT is the greatest publichealth issue in geriatric gynecology. Although its prescription is within the purview of allprimary care providers, as long as women have uteri that may bleed, gynecologists willplay a substantial, and often the only, role in guiding and managing estrogen use. Thissummary addresses several of the topics most pertinent to elderly women. ERT andosteoporosis is addressed in the final section of this chapter.
Despite the huge body of literature published about the impact of ERT on cardiovasculardisease, opinions about benefit and risks conflict in almost every therapeutic aspect. Evenless is clear about the impact of ERT on cardiovascular disease in the elderly womanbecause data are sparse.
The research on estrogen, estrogen-progestin, and selective estrogen receptor modulator (SERM) therapy is reviewed. Except when estrogen alone is designated, the term hormonereplacement therapy (HRT) will be used for both estrogen alone and estrogen plusprogestin when studies either do not distinguish between the two or find little difference inmain outcomes between them. SERMs have estrogenic effects in some organ systems(skeletal, cardiovascular) and antagonistic effects in other organs (breast, uterus). Cur-rently available SERMs in the United States are tamoxifen, raloxifene, and toremifene.
Toremifene is approved for the treatment of metastatic breast cancer. Data on potentialpreventive health benefits of this agent are inadequate and are not reviewed. Studies arecited that use cardiovascular disease, events, or mortality. Many additional studies can befound that report ERT, HRT, and SERM effects on cardiovascular risk factors.
Quality of Data
Estrogen. One systematic review of ERT and cardiovascular disease literature gave infor-
mation specifically on older women. 126 Four randomized controlled trials, 127–130 ten pro-
spective cohort studies, 126,131–139 three case-control studies, 140–142 and one cross–
sectional study 143 were found. Four studies of carotid arterial disease that are relevant to
elderly women were also found—one randomized clinical trial, 144 one cohort study, 145
one case–control study, 146 and one cross-sectional study. 147
Estrogen Dosage. A recent Nurses’ Health Study (NHS) report included 20,000
woman-years of conjugated equine estrogen (CEE) 0.3 mg per day, but ages were not
reported. 131 One epidemiologic study of HRT and myocardial infarction stratified results
by dose. 148
Selective Estrogen Receptor Modulators. Four randomized controlled trials have evalu-
ated tamoxifen use and cardiovascular endpoints. 149–152 No studies of raloxifene with
cardiovascular outcomes have been published.
Estrogen. In a 1991 systematic review of observational studies, 126 Stampfer and Colditz
noted that two previous studies 139,153 found an apparent cardioprotective effect of estro-
gen across all ages, one found a stronger beneficial association in older women, 154 one
found apparent benefit in women of all ages but more in younger women, 142 and one
study with a mean age of 73 showed substantially less cardiovascular disease among HRT
users. 138 Only an early observational publication from the Framingham trial found greater
risk in older women taking HRT, 155 and these conclusions were later essentially re-
tracted. 156 Four recent randomized controlled trials found no coronary heart disease ben-
efit of HRT. Two were from the same 4-year trial, the HERS. 127,128 However, in the last 2
years of the trial, HRT was found to be associated with less coronary heart disease. The
mean age of participants was 67, but no information specific to older women was given.
In a 3-year trial including 309 women, mean age 66 (range 42 to 80), HRT was not foundto affect the progression of coronary atherosclerosis in women with established disease,even when stratified by age. 129 The Women’s Health Initiative (WHI) enrolled womenaged 50 to 79, mean age 63 at baseline, with over 8000 participants in each study arm. 130The estrogen-progestin arm of the trial was stopped prematurely after an average of 5.2years (range 3.5 to 8.5) because of an increase in a global risk index over that withplacebo, which included small but statistically significant increases in nonfatal myocardialinfarction, nonfatal stroke, pulmonary embolism, and deep-vein thrombosis. Age was notfound to interact with HRT effects on any cardiovascular events (data not given). Resultsfrom the estrogen-only participants are still pending.
Most observational cohort studies have found lower coronary heart disease and im- proved survival in older (as well as younger) women taking HRT. The NHS has shownthis in three trials, 131,133,134 which included women to age 75 at the 20-year follow-up,although most were under age 65. Current HRT users were found to have a coronary heartdisease RR of 0.61 (95% CI = 0.52 to 0.71), but results were not stratified by age. AnIowa Women’s Health Study 6-year follow-up (of women aged 55 to 69 years at entry)found current HRT users to have a 25% lower risk of death or coronary heart diseasemortality, 135 with 50% risk reduction if use was longer than 5 years. 132 The LeisureWorld Cohort, mean initial age of 73 years, found a 20% lower all-cause mortality inever-users than in never-users after 7.5 years of follow-up. 136 Current users had betterhealth, but long duration of use was also found to be associated with benefit. However, inthe NHS and the Iowa Women’s Health Study, improved health was found to be associ-ated only with current, not past, use. A Swedish cohort study found greater survival inolder but not younger women who started HRT, probably because of preferential prescrip-tion only to healthy elderly women. 137 Another Swedish cohort study found a lower riskof myocardial infarction in women taking HRT. 157 Two case-control studies and one cross-sectional analysis of older women found less coronary heart disease among HRT users. Kaiser Permanente patients on long-term HRTwere found to have a 46% lower all-cause mortality, largely because there was less coro-nary heart disease. 140 A case-control study of women with a mean age of 65 found 65%less angiographically documented coronary arterial disease among HRT users. 142 Theassociation was significant for women younger than 60 (P = .002) and aged 60 to 69 (P =.03), but not for those aged 70 and over (P= .5). A cross-sectional evaluation of women 65to 100 years old, mean age 72, found a similar reduction in cardiovascular disease in HRTusers both older and younger than 75 years. 143 In addition, an Italian case-control studyfound fewer nonfatal myocardial infarctions among women 60 years and older andyounger than age 60 who had a late menopause. 141 Three cross-sectional analyses and one randomized controlled trial evaluated ERT and carotid arterial disease. ERT use was found to be associated with a decrease in arterialwall thickness in older women. 145–147 In a randomized controlled trial of women aged 40to 70 years, 4 months of ERT was found to be associated with increased carotid arterydistensibility, but not significantly in the subgroup over the age of 59. 144 Estrogen Dosage. The large cohort NHS observed that women using doses of ERT lower
than CEE 0.625 mg per day obtain the same apparent cardioprotection as those using the
standard strength, whereas those using higher estrogen dosages had less. 131,134 Further-
more, stroke risk tended to be less with lower dosages. However, results were not strati-
fied by age, and the number of women in each therapy group is unknown. Oneobservational study found that the reduction of risk for myocardial infarction with CEE0.625 mg per day was not seen with the 0.3 mg dose, but these results were based on asmall number of ERT users. 148 Selective Estrogen Receptor Modulators. Two U.S. randomized controlled trials found a
nonsignificant 150 or no 149 reduction in cardiovascular mortality with tamoxifen use. In
contrast, European trials found a lower risk of fatal myocardial infarction 151,152 and hos-
pitalization for cardiac disease. 158 Potential cardioprotective effects of raloxifene are cur-
rently being evaluated in the Raloxifene Use for The Heart (RUTH) trial. 159
Conflicting results between high-quality large observational trials (showing benefit) andhigh-quality large randomized controlled trials (showing detriment) leave us in a quandaryabout the cardiovascular effects of hormone replacement. The discrepancies seem attribut-able either to crucial differences between the populations being studied, to the drugs beingstudied, or to a “healthy user effect” confounding observational trial outcomes even morethan previously imagined. The randomized trials enrolled primarily older, overweightwomen who had not taken hormones for at least 5 to 10 years since menopause, gave themcontinuous estrogen plus progestin, and studied them for a short time relative to thepostmenopausal life span. The observational trials studied primarily women who tookhormones since menopause, at least half of whom took estrogen only, and whose averagecardiovascular-related health measures (eg, weight, blood pressure, exercise) were betteramong hormone users than nonusers; greatest “benefit” was found with the longest use,although this was sometimes attenuated in advanced age. Interestingly, the most obviouscause of increased cardiovascular risk in the randomized trials could be attributed to aprocoagulant effect of HRT, but the estrogen-only arm of the WHI was not discontinuedprematurely, as would have been expected on the basis of thrombosis alone. Further studyis necessary to understand hormone actions upon the cardiovascular system and to deter-mine the patient characteristics that are associated with benefit and detriment.
At the current time, it is relatively contraindicated to start older postmenopausal women on ERT or HRT. However, the risks and benefits to those who have taken hormones sincemenopause are unclear. Results from the WHI to be completed in 2006 will guide thedirection of current clinical care and future research. Although SERMs may improvecardiovascular risk profiles in older women, their effect on coronary heart disease andlongevity in elderly women is unknown.

The age-specific incidence of Alzheimer’s disease (AD) is higher for women than formen. 160 The effect of estrogen loss at menopause and of hormone replacement on thedevelopment of AD remains in question. Plausible biological theories and laboratory stud-ies support a protective effect, but clinical studies have widely discrepant findings. Fewrisk factors for AD are known, with education being the only well-established modifiableone. Given the devastating nature of the disease and lack of other preventive strategies,hormone use or avoidance becomes an important individual and public health concern.
Quality of Data
Prevention. The biology of AD and potential neuroprotective mechanisms of estrogen
have been well summarized in several reviews of AD and hormone therapy. 160–163 One
randomized controlled trial of HRT for AD prevention has been published. 164 Large co-
horts from which both prospective cohort and nested case-control studies were published
include the Leisure World retirement community, 165,166 a longitudinal study of aging in
Manhattan, 167 the Cardiovascular Health Study, 168 the Baltimore Longitudinal Study on
Aging, 169 the Rancho Bernardo cohort, 170,171 the Duke Established Populations for
Epidemiologic Studies of the Elderly, 172 the Italian Longitudinal Study on Aging, 173 the
United Kingdom General Practice Research Database, 174 and the Cache County Study. 175
Preventive effects of endogenous estrogens were explored within the Study of
Osteoporotic Fractures. 176 One cross-sectional study evaluated cognitive function and
endogenous estrogens and androgens. 171 One longitudinal study compared cognitive
ability over 2 years in older women taking no hormones, estrogen only, and
estrogen-progestin. 177
Treatment. Several clinical trials, including four with placebo control and randomization,
have evaluated the effects of ERT in women with mild or moderate AD. 160,178–180 Many
studies were small or used brief cognitive rating instruments. 160 All randomized con-
trolled trials used oral CEE.
Prevention. The Women’s Health Initiative Memory Study randomized controlled trial
showed worsening dementia with estrogen-progestin use for an average of 5 years (3 to 8)
among women over age 65, 80% of whom had not taken hormones before. 164 AD specifi-
cally was increased with HRT, but at a slightly lower rate than for all-cause dementia.
Among past users of estrogen alone, the increased risk of dementia was found not to be
statistically significant. Too few women had used estrogen-progestin replacement prior to
the study for meaningful comparison with the observational trials of long-term HRT use.
Observational data conflict regarding the protective effect of ERT or HRT use on AD.
Apparent benefit was observed in large prospectively followed cohorts. 167,169,175 In awell-designed and -executed study of 1890 women and 1360 men over age 65 in Utah,incident dementia over a period of 3 years was found to be greater after age 80 amongwomen. Women who had used hormones for more than 10 years (72% unopposed estro-gen, mostly past use) were found to have the same AD incidence as men, whereas nonus-ers were found to have more than twice the risk. Women who used hormones less than 10years had a greater risk of AD (not statistically significant), which essentially concurs withthe randomized trial. 164 There was some suggestion that risk reduction with ERT or HRTis greater in women with two ⑀4 alleles (P = .19). 175 In contrast, one study found lesscognitive decline with estrogen use in women negative for the APOE-⑀4 allele, but not in ⑀4-positive women. 168 In a 2-year prospective study, cognitive performance was found toimprove more for current unopposed estrogen users and less for estrogen-progestin usersthan for nonusers. 177 Another study found ERT use to be associated with less cognitivedecline but not less impairment, but multivariate analyses did not confirm statistical sig-nificance. 172 Unexpectedly, higher serum estrone levels have been associated with worseperformance on two cognitive tests, 176 but free estradiol with less decline. 181 Past, cur-rent, or no ERT use ever was not found to be associated with cognitive function in a largecohort. 170 Retrospective case-control studies, 182–185 nested case-control studies, 165,166 and a cross–sectional study 173 have found less ERT use among demented women or less ADamong ERT users. However, a large nested case-control study found similar odds ratiosfor AD among none ever, past, or current ERT users. 174 A case-control study based onpharmacy records found no association of ERT and AD. 186 Treatment. Most treatment studies have found no benefit of ERT for AD, 160,178,179 the
largest having 120 subjects. 180 One intriguing prospective cohort study within a random-
ized controlled trial found that ERT may enhance response to tacrine. 187 Some AD symp-
toms, such as naming, seem more amenable to improvement with ERT. 188
Estrogen-progestin replacement therapy initiated in women who are several yearspostmenopausal increases the risk of dementia, including AD, with relatively short-termuse. This does not entirely exclude the possibility of a neutral effect or benefit with long-term use, as found in some observational studies. It also does not exclude a potentialbenefit of estrogen alone, nor of HRT initiated at menopause. Discrepancies in studyfindings may relate to subgroups of women who respond favorably or adversely to hor-mones. These subgroups should be sought, to clarify the confusing clinical observations ofpostmenopausal hormone use. ERT has no proven benefit for women with established AD,but benefit in some individuals or synergism with cholinesterase inhibition is not ex-cluded.

The incidence rates for both breast and colon cancer increase with advanced age, and theymay be impacted by ERT or HRT. An abbreviated literature summary with issues pertinentto elderly women is summarized here. An increase in the incidence of endometrial cancerwith the use of unopposed ERT is well understood and does not need comment.
Colon cancer is the leading cause of cancer mortality in women aged 85 and over. A protective influence of hormones was postulated by McMichael and Potter in 1980. 189Given the vast number of observational studies that have looked at ERT and breast cancer,surprisingly little has been studied in elderly women.
Quality of Data
Colon Cancer. Approximately 40 studies have evaluated the association of ERT with
colon cancer, including five meta-analyses, 190–193 and one randomized controlled trial
with partial results. 130
Breast Cancer. Despite the inclusion of many elderly women in breast cancer and ERT
studies, few stratify results by age. The NHS provided data on a subset of women aged 60
to 64. 194 The Collaborative Group on Hormonal Factors in Breast Cancer summarized 51
studies from 21 countries and evaluated associations with age. 195 However, few older
women were estrogen users. One large randomized controlled trial enrolled women to age
79. 130
Selective Estrogen Receptor Modulators and Breast Cancer. The Multiple Outcomes
of Raloxifene Evaluation (MORE) is a large randomized controlled trial that included
women aged 31 to 80 and reported breast cancer results. 196 Eighty percent of the partici-
pants were aged 60 or over, mean age 67. The National Cancer Institute undertook a
randomized controlled trial in 1990 to evaluate tamoxifen for the prevention of breast
cancer in high-risk women. 149 Thirty percent of subjects were aged 60 and older, includ-
ing 6% aged 70 and older.
Colon Cancer. Of 35 observational studies reviewed, 23 suggested a protective effect of
ERT on colon cancer, 11 were neutral, and 1 reported a negative impact. 190 Greater
benefit is generally seen in studies published since 1990, 191 approximating an RR of 0.83
(95% CI = 0.66 to 1.04) in one meta-analysis. 189 The Leisure World cohort study of 7700
older women found 30% less colon cancer in current ERT users. 191 Risk reduction re-
mained but lost statistical significance among past users. Other observational studies have
also found current use but not longer duration to be beneficial. 192,193 A case-control study
found a 65% ERT-related risk reduction, but the 23% reduction in those 70 and older was
not statistically significant. 197 One third or more of subjects in the large randomized WHI
were aged 65 or over. 130 Six fewer colon cancers per 10,000 women per year (statistically
significant) occurred among estrogen-progestin users than with placebo after an average of
5 years (3.5 to 8.5). Age-specific risks were not evaluated.
Breast Cancer. In the NHS, breast cancer risk was found to be 70% higher in 60- to
64-year-old current ERT users who had been taking it at least 5 years. 194 A recent review
of 51 epidemiologic studies, including 52,700 women with breast cancer, found a steady
increase in risk among current ERT users of 1.023 for each year of hormone use. 195 RRs
were 1.3 in women under age 60 and 1.40 in those aged 60 and over. However, the median
age at breast cancer diagnosis was 60, and 92% of users stopped use prior to age 65, thus
offering little information about the older woman. One third or more of subjects in the
large randomized WHI were aged 65 or over. 130 Eight more breast cancers per 10,000
women per year (not statistically significant) occurred among estrogen-progestin users
than among placebo users after an average of 5 years (3.5 to 8.5). No interactions with age
were found.
Selective Estrogen Receptor Modulators and Breast Cancer. Raloxifene use for 3 years
was associated with a 75% breast cancer risk reduction. 196 Estrogen-receptor-positive
cancers were suppressed by 90%, but estrogen-receptor-negative cancers were not.
Tamoxifen use for 4 years was found to reduce invasive breast cancer by 49% in 13,400
mostly younger women; this included a 55% reduction in those aged 60 and over. 149 Noeffect was seen on colon cancer.
Colon Cancer. Colon cancer is decreased among current HRT users, with concurrence of
observational and randomized trial data. Although no study has shown statistical signifi-
cance among women aged 65 and over, this is likely due to lack of data rather than a lack
of effect. The effects of past use are unclear.
Breast Cancer. Long-term and current estrogen-progestin use slightly increases the risk of
breast cancer, with concurrence of observational and randomized trial data. It is unclear
whether age interacts with HRT. The effects of estrogen use alone are uncertain. Only
observational data evaluate breast cancer mortality, which is not higher among HRT users.
Still, relatively few data inform risks for the older woman. SERMs suppress, delay, or
inhibit estrogen-receptor-positive breast cancers in young-elderly women, but study dura-
tions have been relatively short in relation to clinical breast cancer development (7 years).
Gyn 73 (Level B): Cross-sectional or prospective cohort studies should
be performed to determine the factors, whether breast cancer
pathophysiology or other health factors, that are associated with the
apparent lower mortality among women whose breast cancer is di-
agnosed during hormone replacement therapy use.

Gyn 74 (Level B): Observational studies are needed to determine what
functional factors and comorbidities are associated with a lack of
benefit of mammography or colon cancer screening, for the devel-
opment of clinical guidelines.

Gyn 75 (Level B): The results from existing and future studies of estro-
gen, estrogen-progestin, and selective estrogen receptor modulator
use should be stratified by age, even when power is low, to facilitate
systematic reviews.

Gyn 76 (Level A): Randomized trials of continuous therapy since meno-
pause are needed to determine the effects of estrogen and hormone
replacement on breast and colon cancer incidence and mortality.

Gyn 77 (Level A): Randomized trials are needed to determine the effects
of long-term use of selective estrogen receptor modulators on breast
and colon cancer incidence and mortality.

Gyn 78 (Level D): Basic science and observational trials are needed to
determine the mechanisms by which estrogen reduces colon cancer

Gyn 79 (Level C): Randomized trials are needed to determine whether
estrogen or estrogen-progestin replacement after breast cancer
treatment affects recurrence and mortality.

The lifetime risk of osteoporotic fractures in a 50-year-old white woman has been esti-mated to be 30% to 40% in the United States, including a 15% to 18% risk for hipfractures. 198 (See also Chapter 11, section on osteoporosis and falls.) In women aged 60years and over, osteoporosis prevention or treatment has been the predominant reason forinitiation of ERT. 199 A lack of randomized data led to the Food and Drug Administration’swithdrawal of the indication of osteoporosis treatment for ERT, although it is still ap-proved for prevention. Data from more recent research may reverse this. Some data arealso available for SERMs (raloxifene, tamoxifen). Studies on phytoestrogen effects inelderly women have not been published.
Quality of Data
Estrogen. For a thorough discussion of studies pertinent to elderly women, the reader is
referred to reviews of this subject. 198,200–203 Cohort, case-control, and randomized con-
trolled trials evaluate the effects of ERT on BMD and bone turnover in older
women. 200,202 Fracture data regarding elderly women are primarily from observational
studies. 204–212 Most earlier studies suffered from several design flaws, such as including
in the estrogen-user group women who had discontinued ERT use several years earlier. A
meta-analysis of fracture data in older women included published and unpublished reports
of all randomized clinical trials in the preceding decade. 203 The trials are well described
and five include young-old women 128,129,213–215 and two include middle-old
women. 180,216 A recent randomized controlled trial of HRT includes fracture data for
women aged 50 and over. 130
Selective Estrogen Receptor Modulators. A large, well-conducted randomized con-
trolled trial (MORE trial) reported the effect of raloxifene on BMD and fracture risk. 217 A
large, well-described cross-sectional case-control study of tamoxifen and fracture risk was
conducted in nursing-home residents aged 65 years and older. 218
Estrogen. Virtually all studies show improved BMD or bone turnover in the elderly
woman that was essentially equal to that in younger women. 200,202 However, fracture
benefit in older women is less clear. Studies generally show a reduction in risk that does
not achieve statistical significance. Pooled randomized controlled trial data of women
aged 60 and over showed a 21% hip fracture risk reduction (P = .26), and a 12% wrist
fracture risk reduction (P = .63). 203 These results do not prove a lack of ERT benefit,
because most randomized controlled trials were not designed with fracture as the primary
outcome, and the data regarding older women are heavily influenced by the large HERS
trial, 128 in which women with osteoporosis were systematically excluded, thereby limiting
the generalizability of the results. 219 Exclusion of the HERS trial (see above) led to a
more impressive fracture risk reduction of 38% (P = .06). In four observational studies it
is possible to distinguish between women who started HRT before and after age 60
years. 203,204,208,211,212 All show a large reduction in fractures among women starting be-
fore age 60 years, with three studies showing statistical significance. 208,211,212 However,
none found statistical significance among women who started after age 60. ERT was foundto be most effective for hip fracture prevention among long-term and current ERT usersaged 75 or over who started within 5 years of menopause. 211 One third or more of womenin the randomized WHI were aged 65 or over. 130 Twenty-five percent to 35% fewer hip,vertebral, and other osteoporotic fractures occurred in the HRT group than in the placebogroup. Age-specific rates were not given.
Low doses of ERT (0.3 mg esterified estrogen, 25 µg transdermal estrogen, 0.3 mg CEE) improved BMD in several studies, albeit less than standard doses. 202 One random-ized controlled trial in 128 healthy white women aged 65 or over, mean age 73 Ϯ 5 years,found an increase in BMD with low-dose ERT. 216 Fracture data are not available for lowERT doses.
Selective Estrogen Receptor Modulators. The MORE (raloxifene) trial included more
than 7000 osteoporotic women aged 31 to 80 years, mean age 67. 217 Bone density was
found to increase, but nonvertebral fractures were not significantly affected. Age was
mentioned for only one outcome: the 50% reduction in vertebral fracture rate was the
same “across all age groups.” Tamoxifen was found to reduce fracture risk among
nursing-home residents with 10 mg but not 20 mg daily. 218
HRT reduces the risk of osteoporotic fractures, especially when started after menopauseand used long term. The risk reduction when HRT is started in the 60s and 70s is notproven. Evidence points toward a modest (10% to 20%) effect. Low ERT doses helpmaintain BMD, but fracture benefit is unknown. SERMs are potentially an excellent alter-native to ERT for osteoporosis. However, hip fracture data, particularly in middle-old andold-old women, are needed.
Gyn 80 (Level B): Prospective cohort studies are needed to compare the
quality-of-life outcomes of long-term estrogen, estrogen-progestin,
selective estrogen receptor modulator, and bisphosphonate use.

Gyn 81 (Level B): Observational and pilot studies are needed to deter-
mine whether hormone replacement therapy and selective estrogen

fracture-prevention interventions, such as physical therapy for bal-
ance and strength.

Gyn 82 (Levels B, A): Observational and eventually randomized trials
are needed to determine whether low-dose estrogen replacement
therapy initiated at menopause reduces hip, vertebral, and other
osteoporotic fractures in advanced age.

Gyn 83 (Level B): Results from existing and future studies of hormone
replacement to prevent or treat osteoporosis need to be stratified by
age, even when power is low, to facilitate systematic reviews.

Gyn 84 (Level A): Randomized trials are needed to determine the differ-
ences in overall quality of life with hormone replacement therapy,
selective estrogen receptor modulators, and bisphosphonates.

Gyn 85 (Level A): A placebo-controlled randomized trial should be per-
formed to determine whether bisphosphonates, hormone replace-
ment therapy, or selective estrogen receptor modulators best reduce
osteoporosis morbidity and mortality in frail and institutionalized
elderly women, including data on overall cost, burden of care, and
quality of life.

Gyn 86 (Level A): A randomized controlled trial should be performed to
determine the fracture benefit of initiating selective estrogen recep-
tor modulators after age 75 among both osteoporotic and
osteopenic women.

The nonhormonal pharmacotherapeutics most relevant to osteoporosis in elderly womenare nutritional supplementation (reviewed in this section) and bisphosphonates (reviewedin the next section). Other therapies (calcitonin, androgens, fluoride) have less demon-strated efficacy, are poorly studied in elderly women, or may even increase fracture risk.
The need for adequate calcium and vitamin D is well documented. Vitamin D promotes calcium absorption. Its benefit is largely lost within 2 years of discontinuation. 220 Quality of Data
Randomized controlled trials of calcium and vitamin D and of combined therapy usingfracture outcomes in older individuals have been reported. Large trials and moderate-sizedtrials have compared calcium plus vitamin D with placebo, 221–224 calcium with pla-cebo, 225,226 vitamin D with calcium, 227 and vitamin D with placebo. 228 Several smallertrials have compared vitamin D with placebo, calcium, and other forms of vitamin D. 220Dietary calcium and fracture associations were prospectively assessed in a large co-hort. 229 Results
Administration of vitamin D plus calcium was found to reduce hip, nonvertebral, andvertebral fractures in elderly women. 221–223 The Finnish study did not demonstrate frac-ture reduction, but power to do so and treatment duration were low. 224 Vitamin D alonewas not found to reduce hip fractures in 2600 healthy and frail elderly women. 228 Cal-cium supplementation was found to lower the vertebral fracture rate in elderly womenwith baseline vertebral fractures, but not in those without. 225,226 Current calcium use wasfound to be associated with an increased hip-fracture risk in a large cohort, but this waspresumed to be due to confounding by indication for supplements. 229 Summary
Adequate intake of both vitamin D and calcium reduces fracture risk, and both are mostimportant in those who are deficient or osteoporotic. Both together reduce vertebral andnonvertebral fractures in elderly women. Randomized data for the use of calcium aloneare weak; data for vitamin D alone are slightly stronger, but still not certain.
Gyn 87 (Level D): Observational trials and pilot studies are needed to
determine the importance of factors in adolescence, such as milk
and carbonated beverage consumption, on peak bone mass and
bone matrix.

Gyn 88 (Level D): Observational studies are needed to define the costs
and side effects associated with calcium and vitamin D supplemen-

Gyn 89 (Level C): Randomized trials are needed to determine the opti-
mal time in a woman’s life span to benefit from calcium supplemen-

Gyn 90 (Level C): Randomized trials should be performed to determine
the best method of calcium supplementation to maximize absorp-
tion and minimize side effects.

Gyn 91 (Level C): Randomized trials are needed to determine the best
form of vitamin D supplementation.
Although the mechanism of action of bisphosphonates is incompletely understood, theyhave proven to be profoundly effective in the prevention and treatment of osteoporosis.
Quality of Studies
Bisphosphonates have undergone rigorous clinical efficacy trials, since their use forosteoporosis is a fairly new indication. Available data include randomized controlled trialsin elderly women.
Alendronate. A meta-analysis including five randomized controlled trials published in
1994 and 1995 of alendronate use for at least 2 years reported data dichotomized at age
65. 230 Women aged 55 to 81 with and without existing vertebral fractures were studied in
the Fracture Intervention Trial (FIT). 231–233
Risedronate. The Vertebral Efficacy with Risedronate Therapy (VERT) trial reported ap-
proximately 1000 women, mean age 69, with low bone density and baseline vertebral
fractures. 234
Etidronate. Four etidronate randomized controlled trials with elderly women reported
fracture data. 235–238
Alendronate. In the meta-analysis, the RRs for fracture ranged from 0.34 to 0.91, with the
greatest risk reduction in those aged 65 and over. 230 In the FIT trial, women with a
baseline vertebral fracture were found to have a reduced risk of subsequent vertebral or
nonvertebral fracture. 231 Among women without a baseline vertebral fracture, only the
risk for vertebral fracture was reduced. Results were consistent across age groups. 232
Among the women with baseline hip osteoporosis, the 36% reduction in clinical fractures
was statistically significant, but no effect was demonstrable in women with higher
baseline BMD.
Risedronate. Risedronate was found to reduce vertebral and nonvertebral fractures sig-
nificantly in women with baseline osteoporosis, although in one report the nonvertebral
fracture risk reduction was of borderline certainty (P = .06). 234,239 A trial of risedronate in
9000 severely osteoporotic women aged 70 or older (hip T score Ͼ 4.0) found a 30%
decrease in hip fracture risk among those aged 70 to 79, but not significantly in women
aged 80 and older (P = .35). 240
Etidronate. In three of the four randomized controlled trials, mean ages 65 to 72 years,
vertebral but not nonvertebral fractures were reduced. 235,236,238
Bisphosphonates are well studied in elderly women and are effective. Alendronate de-creases vertebral and nonvertebral fractures in osteoporotic women. A significant benefitin elderly women without osteoporosis is unlikely with therapy of short duration (Ͼ 4years). Risedronate effectively lowers fracture rates in elderly osteoporotic women, al-though hip fracture benefit is less certain. Trials have included only osteoporotic women,so the preventive benefits of this agent are unknown. Etidronate is not first-linebisphosphonate therapy.
Gyn 92 (Level B): Long-term observational studies are needed to obtain
information about the efficacy, safety, and adverse effects of very
long-term bisphosphonate use (30 to 40 years) for postmenopausal
osteoporosis prevention and treatment.

Gyn 93 (Level B): Medications that selectively reduce bone resorption
without limiting bone formation should be developed.
Gyn 94 (Level B): Medications that stimulate bone formation should be
Gyn 95 (Level A): Randomized controlled trials are needed to determine
the utility of bisphosphonates for osteoporosis benefit in healthy

Gyn 96 (Level A): Randomized controlled trials should be performed to
determine the additive effects, if any, of hormonal and
nonhormonal osteoporosis therapies.

Gyn 97 (Level D): Decision and cost-effectiveness analyses are needed to
calculate whether health care dollars spent on medication, includ-
ing evaluation and management of complications, would be better
spent on physical and occupational therapy in frail elderly women.

Gyn KQ1: How can the immediate and long-term functional impact of
gynecologic surgery on older women be improved?
Hypothesis-generating: Prospective or cross-sectional cohort studies are needed to give clues to the functional impact of gynecologic surgery onelderly women of differing functional status.
Hypothesis-testing studies are needed to define what preoperative, intraoperative, and postoperative interventions enhance functional recovery.
Hypothesis-testing studies are needed to establish benefits and risks of es-trogen replacement therapy preoperatively, both locally for incontinenceand prolapse surgery, and systemically on the cardiovascular and hemato-logic systems (eg, thrombophilia).
Gyn KQ2: How can normal urogenital function be maintained in aging
and age-related conditions?
Hypothesis-generating: Observational studies are needed to understand the epidemiology of urogenital disorders other than urinary incontinence,including vulvovaginal conditions, pelvic organ prolapse, and sexual dys-function. Observational studies are needed to suggest preventive and thera-peutic interventions (other than estrogen therapy) to minimize urinaryincontinence, vulvovaginitis. Hypothesis-generating studies are needed to find potentialtherapeutic interventions for sexual dysfunction in older women.
Hypothesis-testing studies are needed to determine the impact of estro- gen replacement therapy on urogenital health. Hypothesis-testing studiesare needed to evaluate the functional and quality-of-life benefits of cur-rently available interventions for urinary incontinence and pelvic organprolapse, including behavioral programs and pelvic floor reparative proce-dures. Hypothesis-testing studies are needed for the treatment of urinaryincontinence in demented elderly women.
Gyn KQ3: Which older women should be encouraged to initiate or con-
tinue estrogen replacement or other hormonal therapy?
Hypothesis-generating: Observational studies are needed to sort out complex relationships among age, hormone replacement, and genetic andenvironmental predisposition to disease.
Hypothesis-testing studies are needed to establish the impact of selective estrogen receptor modulators and long-term (Ͼ 10 years) estrogen andestrogen-progestin replacement therapy on conditions that affect a largenumber of elderly women—cardiovascular disease, stroke, dementia, coloncancer, breast cancer, age-related macular degeneration, cataracts, poordentition, arthritis, and osteoporosis. Sexual function issues should be in-cluded among the outcomes studied. Studies are needed to address theseveral hormone replacement therapeutic options, such as dose, route ofadministration, types and schedules of progestins, and the use of selectiveestrogen receptor modulators instead of estrogens and progestins. In allstudies, the questions of continuation in old age should be addressed.

What Is Molluscum? Molluscum lesions affect as many as 20 percent of children over the course of childhood. This common condition is caused by the Molluscum contagiosum virus (MCV), a highly contagious poxvirus easily passed from child to child. Mollusucm is an annoyance for many children and parents because of how long the lesions take to disappear. Left alone, molluscum lesions do disa
