BACKGROUND: Patients with breast cancer who have a pathologic complete response (pCR) to neoadjuvant chemotherapy (NACT) have improved survival. We hypothesize that once pCR has been achieved, there is no difference in subsequent postsurgical recurrence-free survival (RFS), whichever NACT regimen is used. METHODS: Data from patients with breast cancer who achieved pCR after NACT between 1996 and 2011 were reviewed. RFS was estimated by the Kaplan-Meier method, and differences between groups were assessed using log-rank testing...

Menopause-related depression devastates women's quality of life after middle age. Previous research has shown that estrogen hormone therapy has serious adverse effects; thus, complementary and integrative therapies have been considered clinically. The present study investigates whether stimulation of an acupoint using a mechanical acupuncture instrument (MAI) can mitigate depression-like behavior caused by estrogen deficiency in ovariectomized (OVX) rats. The animals were divided into Sham OVX, OVX, OVX + Sameumgyo (SP6) and OVX + NonAcu (non-acupuncture point) groups...

Oxidative stress (OS) is a key process in the development of many neurodegenerative diseases, memory disorders, and other pathological processes related to aging. Tibolone (TIB), a synthetic hormone used as a treatment for menopausal symptoms, decreases lipoperoxidation levels, prevents memory impairment and learning disability caused by ozone (O3 ) exposure. However, it is not clear if TIB could prevent the increase in phosphorylation induced by oxidative stress of the microtubule-associated protein Tau. In this study, the effects of TIB at different times of administration on the phosphorylation of Tau, the activation of glycogen synthase kinase-3β (GSK3β), and the inactivation of Akt and phosphatases PP2A and PTEN induced by O3 exposure were assessed in adult male Wistar rats...

Menopause is an important transition in the life of women. It has been estimated that by the year 2030, worldwide 1.2 billion women will be menopausal. The most bothersome symptoms of menopause are believed to be due to declines in estrogen levels in postmenopausal women. Thus, hormone therapy is an effective treatment option for menopausal women, although prolonged use of hormone therapy is associated with a slightly increased risk of breast cancer, thromboembolism, and stroke. A literature search for studies evaluating the effects of hormone therapy in menopausal women with asymptomatic fibroids demonstrated variable effects of hormone therapy on the volume and size of the fibroids...

This review aims to draw a clearer clinical picture of postmenopausal endometriosis. Based on limited literature, postmenopausal endometriosis emerges as an infrequent entity but with a clinical picture significantly unlike that of premenopausal endometriosis. In contrast to the premenopausal disease, postmenopausal endometriosis occurs in a state of ovarian estrogen deficiency, appears to have a greater predisposition to malignant change, may have a greater tendency to spread to extragonadal organs and develop into constrictive and/or obstructive lesions, and is preferably treated surgically...

Context: Following menopause fat mass (FM) and visceral adipose tissue (VAT) increase, while non-bone lean mass (LBM) decreases. Whether menopausal hormone therapy (MHT) reverses these changes remains controversial. Objective: To assess the effect of MHT on FM, VAT and LBM before and after its withdrawal and evaluate potential confounders. Design: Cross-sectional study. Setting: General community. Patients or Other Participants: Women of the OsteoLaus cohort (50-80 years old) who underwent dual-energy X-ray absorptiometry (DXA) with body composition assessment...

BACKGROUND: It is estimated that 1-2.5 million U.S. women use compounded bioidentical menopausal hormone therapy (MHT). However, the proportion of American physicians prescribing compounded bioidentical hormones remains unknown. This study aims to evaluate obstetrician-gynecologists' (OB/GYNs) and family medicine physicians' decisions reflected in prescribing practices of MHT in Kansas, and level of agreement with the American College of Obstetricians and Gynecologists (ACOG) recommendations...

It is well established that unopposed estrogen for hormone therapy in postmenopausal women (MHT) induces a dose-related stimulation of the endometrium associated with an increased risk of hyperplasia and endometrial cancer. Progesterone acts physiologically to counteract the proliferative effects of estradiol during the menstrual cycle. In MHT, progestogens protect the endometrium against the proliferative effects of estrogens in women with a uterus. Recent data suggest that, whereas micronized progesterone is apparently safer for the breast, it could be less efficient than synthetic progestin on the endometrium...

Currently, the growing population of the elderly is one of biggest problems in terms of increase in geriatric diseases. Lack of data from large prospective studies on geriatric breast cancer patients often makes it difficult for clinicians to make treatments decisions for them. Because both benefit and risk of treatment should be taken into account, treatment is usually determined considering life expectancy or comorbidities in elderly patients. Treatment of breast cancer is differentiated according to histologic classifications, and hormone therapy is even adopted for patients with metastatic breast cancer if tumor tissue expresses hormone receptors...

The Women's Health Initiative studies reported that the menopausal hormone therapy (MHT) regimen containing conjugated equine estrogen (CEE) and medroxyprogesterone acetate increased, whereas CEE alone reduced breast cancer incidence. These observations suggest the possibility that CEE might exert unique actions on breast and also suggest the need to eliminate the progestogen from MHT regimens. A MHT regimen called a tissue selective estrogen complex (TSEC), containing CEE plus bazedoxifene (BZA), to avoid the need for a progestogen, was developed and FDA approved...

Preservation of bone health remains a long-term clinical challenge in patients with breast and prostate cancer. Osteoporosis, defined by a loss of bone mass and microarchitecture, often results in fragility fractures that are typically associated with a high socioeconomic burden. Endocrine therapy, a mainstay treatment in the management of patients with hormone-sensitive breast and prostate cancer in the adjuvant setting, commonly exerts adverse effects on the musculoskeletal system and is associated with an increased risk of osteoporosis and fractures...

Postmenopausal hormone therapy (HT) is a modifiable risk factor for venous thromboembolism (VTE). While the route of estrogen administration is now well recognized as an important determinant of VTE risk, there is also increasing evidence that progestogens may modulate the estrogen-related VTE risk. This review updates previous meta-analyses of VTE risk in HT users, focusing on the route of estrogen administration, hormonal regimen and progestogen type. Among women using estrogen-only preparations, oral but not transdermal preparations increased VTE risk (relative risk (RR) 1...

Body size is an important modifiable risk factor for postmenopausal breast cancer. However, it remains unclear whether direct measures of fat mass are better indicators of risk than anthropometric measures, or whether central adiposity may contribute to risk beyond overall adiposity. We analyzed data from 162,691 postmenopausal women in UK Biobank followed from 2006-2014. Body size was measured by trained technicians. Multivariable-adjusted Cox regression was used to estimate relative risks. Analyses were stratified by age at recruitment, region, and socioeconomic status, and adjusted for family history of breast cancer, age at menarche, age at first birth, parity, age at menopause, previous hormone replacement therapy use, smoking, alcohol intake, height, physical activity, and ethnicity...

Objective Referral audit - are local recommendations required to translate guideline to practice? Study design In total, 50 consecutive, anonymised referral letters reviewed during the initial consultation in a specialist menopause clinic; the reasons for referral along with the patient's age and the source of referral were analysed. Results Several common reasons for referral were identified. Sexual dysfunction, including loss of libido and dyspareunia, resulted in 11 (22%) referrals. Ten (20%) women were troubled by persistent symptoms or side effects from HRT; 9 (18%) women were referred before hormone replacement therapy was discussed or commenced; 7 (14%) women seeking advice for their menopausal symptoms had a family or personal history of cancer; 5(10%) were migraineurs; 2(4%) women had premature ovarian insufficiency; 2(4%) were denied hormone replacement therapy because of concern about venous thromboembolism risk; and 4 (8%) had miscellaneous medical disorders...

Aim: Gonadal hormones are essential for reproductive function, but can act on neural and other organ systems, and are probably the cause of the large majority of known sex differences in function and disease. The aim of this review is to provide evidence for this hypothesis in relation to eye disorders and to retinopathies in particular. Methods: Epidemiological studies and research articles were reviewed. Results: Analysis of the biological basis for a relationship between eye diseases and hormones showed that estrogen, androgen, and progesterone receptors are present throughout the eye and that these steroids are locally produced in ocular tissues...
