Postmenopausal hormone therapy and the risk of breast cancer. A clinician's view.

Reports from the Women's Health Initiative (WHI) and the Million Women Study have indicated that postmenopausal hormone therapy increases the risk of breast cancer. At this point in time, it is not certain whether these data reflect a small increase in risk or an impact of hormone therapy on pre-existing tumors. The purpose of this review is to provide an analysis of the epidemiologic data that can help the clinician inform patients and assist patients in their decision-making.

Costs and net health effects of contraceptive methods.

BACKGROUND: Pregnancy and contraceptive methods both have important health effects that include risks and benefits. The net impact of contraception on women's health has not been reported previously. STUDY DESIGN: This is a cost-utility analysis using a Markov model evaluated by Monte Carlo simulation using the societal perspective for costs. The analysis compared 13 methods of contraception to nonuse of contraception with respect to healthcare costs and quality-adjusted life years (QALYs). Discounting was applied for future costs and health effects. The base-case analysis applies to women of average health and fertility, ranging from 15 to 50 years of age, who are sexually active in a mutually monogamous relationship; smoking rates observed in women of reproductive age were used. Sensitivity analysis extended the analysis to nonmonogamous status and smoking status. RESULTS: Compared with use of no contraception, contraceptive methods of all types result in substantial cost savings over 2 years, ranging from US$5907 per woman for tubal sterilization to US$9936 for vasectomy and health gains ranging from 0.088 QALYs for diaphragm to 0.147 QALYs for depot medroxyprogesterone acetate. Compared with nonuse, even with a time horizon as short as 1 year, use of any method other than sterilization results in financial savings and health gains. Most of the financial savings and health gains were due to contraceptive effects. In a population of patients, even modest increases in the use of the most effective methods result in financial savings and health gains. CONCLUSIONS: Every method of contraception dominates nonuse in most clinical settings. Increasing the use of more effective methods even modestly at the expense of less effective methods will improve health and reduce costs. Methods that require action by the user less frequently than daily are both less costly and more effective than methods requiring action on a daily basis.

Postmenopausal hormone therapy and breast cancer: a clinician's message for patients.

The Women's Health Initiative agrees with some but not all case-control and cohort studies that current use of postmenopausal estrogen-progestin therapy is associated with a small increase in the risk of breast cancer. It is not known whether this is because of new tumor growth or an effect of hormonal therapy on preexisting tumors. Many studies indicate that women who develop breast cancer while using postmenopausal hormone therapy have a reduced risk of dying from breast cancer; this is consistent with an effect on preexisting tumors so that tumors appear at a less virulent and aggressive stage.

HT. A clinician demurs.

The ongoing challenge to clinicians is to make medical judgments that are suitable for patients as individuals with unique combinations of medical needs. The cancellation of the WHI study's estrogen/progestin arm leaves unanswered questions that will affect clinicians' medical decisions.

Endometrial effects of lower doses of conjugated equine estrogens and medroxyprogesterone acetate: two-year substudy results.

OBJECTIVE: To determine the endometrial safety of 2 years of treatment with lower doses of continuous combined conjugated equine estrogens (CEE) and medroxyprogesterone acetate (MPA). DESIGN: Randomized, double-blind, placebo-controlled, multicenter metabolic and osteoporosis substudy of the Women's Health, Osteoporosis, Progestin, Estrogen (Women's HOPE) study. SETTING: Nineteen study centers across the United States. PATIENT(S): Healthy, postmenopausal women (n = 822) with an intact uterus were recruited. INTERVENTION(S): Patients received CEE 0.625, CEE 0.625/MPA 2.5, CEE 0.45, CEE 0.45/MPA 2.5, CEE 0.45/MPA 1.5, CEE 0.3, CEE 0.3/MPA 1.5 (all doses mg/day), or placebo for 2 years. Endometrial biopsies were evaluated at baseline and years 0.5, 1, 1.5, and 2 using a centralized protocol. MAIN OUTCOME MEASURE(S): Efficacy of lower doses of CEE/MPA in reducing the incidence of endometrial hyperplasia rates associated with unopposed estrogen (E). RESULT(S): No cases of endometrial hyperplasia were seen in the four CEE/MPA groups. For the CEE-alone groups, a dose-related increase in incidence rates from 3.17% (CEE 0.3 mg) to 27.27% (CEE 0.625 mg) was seen at 2 years. The number of cases increased from year 1 to year 2. For the CEE-alone groups, the incidence rates and types of hyperplasia diagnosed varied among the pathologists. CONCLUSION(S): Two years of treatment with lower doses of CEE/MPA provided endometrial protection comparable to that seen with commonly prescribed doses. These regimens should be considered for postmenopausal women who are candidates for hormone therapy.

Efficacy and tolerability of a novel estradiol vaginal ring for relief of menopausal symptoms.

OBJECTIVE: To assess the efficacy, tolerability, and acceptance of a vaginal ring delivering the equivalent of 50 or 100 microg per day of estradiol (E2), compared with placebo, for relief of moderate to severe vasomotor symptoms and urogenital symptoms in postmenopausal women. METHODS: Women with moderate to severe vasomotor symptoms (seven or more per day or 56 per week average) received 13 weeks of treatment with a vaginal ring delivering 50 microg per day E2 (n = 113) or 100 microg per day E2 (n = 112), or a placebo vaginal ring (n = 108). Severity of vasomotor symptoms was assessed by a daily diary card and the Greene Climacteric Scale. Urogenital signs and symptoms were evaluated via patient and physician assessment and vaginal cytology. Participant satisfaction with the vaginal ring was evaluated via questionnaire. RESULTS: Vasomotor symptoms significantly improved in both treatment groups, compared with placebo (P <.05). There was a trend toward greater improvement in patient assessment of urogenital signs with active rings compared with placebo. For women with vaginal atrophy at baseline (n = 60), the maturation index improved significantly in both treatment groups compared with placebo. Total Greene Climacteric Scale scores significantly improved for both E2 vaginal ring groups (P <.05) compared with placebo. The vaginal rings were well tolerated. Most adverse events were mild or moderate and consistent with estrogen therapy. CONCLUSION: A novel vaginal ring delivering the equivalent of 50 or 100 microg per day of E2 significantly reduced the number and severity of vasomotor symptoms and improved urogenital symptoms, compared with placebo. The E2 vaginal ring was well tolerated.

Reduced vaginal bleeding in postmenopausal women who receive combined norethindrone acetate and low-dose ethinyl estradiol therapy versus combined conjugated equine estrogens and medroxyprogesterone acetate therapy.

OBJECTIVE: The purpose of this study was to compare the effects on vaginal bleeding patterns of continuous combined hormone replacement therapy with norethindrone acetate and ethinyl estradiol versus conjugated equine estrogens and medroxyprogesterone acetate. STUDY DESIGN: Three hundred fifty-seven postmenopausal women were selected randomly (in a blinded manner) to 12 months of treatment with 1 mg norethindrone acetate/5 microg ethinyl estradiol, placebo, or open-label 0.625 mg conjugated equine estrogens/2.5 mg medroxyprogesterone acetate (conjugated equine estrogens/medroxyprogesterone acetate [CEE/MPA]; Prempro). The incidence and duration of vaginal bleeding were assessed throughout the study. Statistical analyses used Cochran-Mantel-Haenszel methodology and analysis of variance. RESULTS: At 3 months, 1 mg norethindrone acetate/5 microg ethinyl estradiol therapy reduced the incidence of bleeding (12% vs 23%; P <.029) and bleeding and/or spotting (22% vs 44%; P <.001), compared with conjugated equine estrogens/medroxyprogesterone acetate therapy. The mean duration of bleeding and bleeding and/or spotting were also reduced with 1 mg norethindrone acetate/5 microg ethinyl estradiol therapy versus conjugated equine estrogens/medroxyprogesterone acetate (P =.004 and P <.001, respectively). The incidence of cumulative amenorrhea at every monthly interval was significantly better with 1 mg norethindrone acetate/5 microg ethinyl estradiol therapy versus conjugated equine estrogens/medroxyprogesterone acetate therapy (P <.05). Associated adverse event (ie, headache, breast pain) incidence rates were similar in the 2 active treatment groups. CONCLUSION: The 1 mg norethindrone acetate/5 microg ethinyl estradiol therapy provides significantly better control of vaginal bleeding than conjugated equine estrogens/medroxyprogesterone acetate therapy at all time points investigated in this 12-month study.

The perimenopause: definitions, demography, and physiology.

The perimenopausal years should serve to remind patients and clinicians that this is a time for education. Certainly preventive health care education is important throughout life, but at the time of midlife, a review of the major health issues can be especially rewarding. The failure to respond appropriately (by either clinician or patient) easily leads to a loss of the patient from a practice, but equally, if not more importantly, is the probability that the loss of a patient from a practice means that another woman has lost her involvement in a preventive health care program. Contrary to popular opinion, the menopause is not a signal of impending decline, but rather a wonderful phenomenon that can signal the start of something positive, a good health program.
