Although hormone replacement therapy (HRT) use is associated with elevated endometrial cancer(EC) risk, little evidence assesses potential effect-modifiers on HRT-related EC in a long-term follow-up. In this large-scale longitudinal cohort study, we tried to evaluate the association between different HRT types/methods use and risk of EC, and reveal this risk within different body mass index (BMI) groups. In whole cohort, 677 EC occurred during mean 11.6 years follow-up. Cox proportional hazards regression was used to estimate multivariable-adjusted hazards ratios (HRs) and 95% confidence intervals (CIs) with HRT status (never, former, or current) for risk of EC incidence. Current HRT use was not significantly associated with EC risk (HR for current vs. never HRT use: 1.13; 95% CI: 0.92, 1.38) in the whole cohort, but presented a dose-response effect on increased EC risk (HR for >10-year use vs. never HRT use: 1.73; 95% CI: 1.35, 2.21). Moreover, EC risk differed in distinct regimens or subsets (all Pinteraction < 0.05). Estrogen-only use was associated with elevated EC risk (HR for current vs. never HRT use: 1.51; 95% CI: 1.12, 2.04), but women with high BMI (> 30 kg/m2) who currently use estrogen-only harbored decreased EC risk (HR: 0.56; 95% CI: 0.38, 0.82) compared to counterparts without HRT use. Estrogen-only use is associated with increased EC risk, and precise monitoring of EC development for postmenopausal women with long-term HRT use are urgently needed. BMI could serve as an important surrogate to assess this risk.

OBJECT The incidence of subarachnoid hemorrhage (SAH) increases after menopause. Anecdotal data suggest that hormone replacement therapy (HRT) may reduce the rate of SAH and aneurysm formation in women. The goal of this study was to determine the effect of HRT on occurrence of SAH in a large prospective cohort of postmenopausal women. METHODS The data were analyzed for 93, 676 women 50–79 years of age who were enrolled in the observational arm of the Women’s Health Initiative Study. The effect of HRT on risk of SAH was determined over a period of 12 ± 1 years (mean ± SD) using Cox proportional hazards analysis after adjusting for potential confounders. Additional analysis was performed to identify the risk associated with “estrogen only” and “estrogen and progesterone” HRT among women. RESULTS Of the 93, 676 participants, 114 (0.1%) developed SAH during the follow-up period. The rate of SAH was higher among women on active HRT compared with those without HRT used (0.14% vs 0.11%, absolute difference 0.03%, p < 0.0001). In unadjusted analysis, participants who reported active use of HRT were 60% more likely to suffer an SAH (RR 1.6, 95% CI 1.1–2.3). Compared with women without HRT use, the risk of SAH continued to be higher among women reporting active use of HRT (RR 1.5, 95% CI 1.0–2.2) after adjusting for age, systolic blood pressure, cigarette smoking, alcohol consumption, body mass index, race/ethnicity, diabetes, and cardiovascular disease. The risk of SAH was nonsignificantly higher among women on “estrogen only” HRT (RR 1.4, 95% CI 0.91–2.0) than “estrogen and progesterone” HRT(RR 1.2, 95% CI 0.8–2.1) after adjusting for the above-mentioned confounders. CONCLUSIONS Postmenopausal women, particularly those at risk for SAH due to presence of unruptured aneurysms, family history, or cardiovascular risk factors, should be counseled against use of HRT.

Objective: To estimate the effect of oestrogen-only and combined hormone replacement therapy (HRT) on the hazards of overall and age-specific all-cause mortality in healthy women aged 46 to 65 at first prescription. Design: Matched cohort study. Setting: Electronic primary care records from The Health Improvement Network (THIN) database, UK (1984−2017). Population: 105,199 HRT users (cases) and 224,643 non-users (controls) matched on age and general practice. Methods: Weibull-Double-Cox regression models adjusted for age at first treatment, birth cohort, type 2 diabetes, hypertension and hypertension treatment, coronary heart disease, oophorectomy/hysterectomy, body mass index, smoking, and deprivation status. Main outcome measures: All-cause mortality. Results: A total of 21,751 women died over an average of 13.5 years follow-up per participant, of whom 6,329 were users and 15,422 non-users. The adjusted hazard ratio (HR) of overall all-cause mortality in combined HRT users was 0.91 (95%CI 0.88−0.94), and in oestrogen-only users was 0.99 (0.93−1.07), compared to non-users. Age-specific adjusted HRs for participants aged 46-50, 51-55, 56-60, and 61-65 years at first treatment were 0.98 (0.92−1.04), 0.87 (0.82−0.92), 0.88 (0.82−0.93), and 0.92 (0.85−0.98), for combined HRT users compared to non-users, and 1.01 (0.84−1.21), 1.03 (0.89−1.18), 0.98 (0.86−1.12), and 0.93 (0.81−1.07) for oestrogen-only users, respectively. Conclusions: Combined HRT was associated with a 9% lower risk of all-cause mortality and oestrogen-only formulation was not associated with any significant changes. Funding: IFoA. Keywords: Hormone replacement therapy, menopause, mortality, primary care records, THIN. Tweetable abstract: Oestrogen-only HRT is not associated with all-cause mortality and combined HRT reduces the risks.
