OBJECTIVE: Despite benefits of adjuvant hormonal therapy (AHT), many eligible breast cancer patients do not complete therapy as recommended. Patterns of AHT use have not been well studied among uninsured breast cancer patients who fall into coverage gaps or are ineligible for public insurance programs. METHODS: We identified 291 patients newly diagnosed with stages I-III hormone receptor-positive breast cancer from January 2008 to December 2012. All patients were treated at a safety-net healthcare system and enrolled in an income-based medical assistance program that fills AHT prescriptions at low cost...

PURPOSE: Many patients with breast cancer are treated for other conditions and experience polypharmacy with multiple concurrent medications. Our aim was to evaluate polypharmacy in relation to adherence to adjuvant endocrine therapy (AET) in breast cancer. METHODS: We conducted a retrospective cohort study of women with incident, invasive breast cancer initiating AET (tamoxifen, letrozole, anastrozole, exemestane) between 2009 and 2013 in the Truven Health MarketScan Database...

PURPOSE: Several lines of evidence support targeting the androgen signaling pathway in breast cancer. Enzalutamide is a potent inhibitor of androgen receptor signaling. Preclinical data in estrogen-expressing breast cancer models demonstrated activity of enzalutamide monotherapy and enhanced activity when combined with various endocrine therapies (ETs). Enzalutamide is a strong cytochrome P450 3A4 (CYP3A4) inducer, and ETs are commonly metabolized by CYP3A4. The pharmacokinetic (PK) interactions, safety, and tolerability of enzalutamide monotherapy and in combination with ETs were assessed in this phase I/Ib study...

PURPOSE: Cyclin-dependent kinase (CDK) 4/6 drives cell proliferation in estrogen receptor positive (ER+) breast cancer. This single-arm phase II neoadjuvant trial (NeoPalAna) assessed the anti-proliferative activity of the CDK4/6 inhibitor palbociclib in primary breast cancer as a prelude to adjuvant studies. EXPERIMENTAL DESIGN: Eligible patients with clinical stage II/III ER+/HER2- breast cancer received anastrozole 1mg daily for 4 weeks (cycle 0) (with goserelin if premenopausal), followed by adding palbociclib (125mg daily on days 1-21) on cycle 1 day 1 (C1D1) for four 28-day cycles unless C1D15 Ki67>10%, in which case patients went off study due to inadequately response...

Aromatase inhibitors (AIs) as effective candidates have been used in the treatment of hormone-dependent breast cancer. In this study, we have proposed 300 structures as potential AIs and filtered them by Lipinski's rule of five using DrugLito software. Subsequently, they were subjected to docking simulation studies to select the top 20 compounds based on their Gibbs free energy changes and also to perform more studies on the protein-ligand interaction fingerprint by AuposSOM software. In this stage, anastrozole and letrozole were used as positive control to compare their interaction fingerprint patterns with our proposed structures...

Adjuvant (hormonal) therapy is the main method of treatment after surgery in hormone (estrogen and/or progesterone) positive breast cancer patients. The goal of above mentioned treatment is to reduce or block the level of estrogen and progesterone. ultiple clinical trials have revealed that hormonal therapy in breast cancer patients affect bone mineral density (BMD). Authors have analyzed data obtained from several clinical trials conducted in several countries (including Georgia). The final conclusion is that selective estrogen receptor modulators (SERMs) have negative effect on BMD in pre-menopausal women and aromatase inhibitors (anastrozole, letrozole, exemestane) are associated with significant bone loss in post-menopausal women...

The optimal duration and treatment strategies involving adjuvant endocrine therapy in early breast cancer remained largely undetermined. As data emerge on the various modalities of treatment in both pre- and postmenopausal groups, debates, and discussions continue. Most studies to date focused on the 5-year duration of treatment consisting of mainly tamoxifen. The Arimidex, Tamoxifen, Alone or in Combination (ATAC) study demonstrated that anastrozole is superior to tamoxifen and has become the mainstream treatment in postmenopausal women with early breast cancer, although the duration was arbitrarily set for 5 years, analogous to tamoxifen treatment...

The immunologic potency of IgG is modulated by glycosylation, but mechanisms regulating this process are undefined. A role for sex hormones is suggested by differences in IgG glycans between women and men, most prominently with respect to galactose. We therefore assessed IgG galactosylation in 713 healthy adults from 2 cohorts as well as in 159 subjects from 4 randomized controlled studies of endocrine manipulation: postmenopausal women receiving conjugated estrogens, raloxifene, or placebo; premenopausal women deprived of gonadal hormones with leuprolide and treated with estradiol or placebo; men deprived of gonadal hormones with goserelin and given testosterone or placebo; and men deprived of gonadal hormones with goserelin and given testosterone or placebo together with anastrozole to block conversion of testosterone to estradiol...

Objective Obesity is associated with an increased risk for breast cancer. Recent studies have shown that aromatase inhibitors may be less effective in women with a high body mass index (BMI). The aim of this study was to establish the relationship between the BMI and plasma estrone and estradiol levels in postmenopausal women with hormone receptor-positive breast cancer using anastrozole. Methods In this cohort study, the patients were divided into three groups according to BMI (normal weight, overweight and obese) to compare and correlate plasma hormone levels before starting anastrozole hormone therapy and three months after treatment...

A 50-year old woman noticed left axillary lymph node swelling and presented at our hospital. CNB showed adenocarcinoma( pap-tub, ER+, PgR+, HER2 3+). CT revealed a right lung metastatic nodule and swollen lymph nodes above the left collarbone and left axilla. However, no breast tumor was found at that time. We diagnosed occult breast cancer, TxN3bM1 (lung), Stage IV . FEC(100), paclitaxel, letrozole, anastrozole, exemestane plus trastuzumab, tegafur/uracil plus trastuzumab, and lapatinib plus capecitabine were sequentially administered...

We report a case of recurrent breast cancer with involvement of the right adrenal grand, which was resected using laparoscopic surgery. The patient was a 41-year-old woman who underwent duct-lobular segmentectomy for ductal carcinoma in situ. Histopathology showed microinvasion, and tested positive for ER and PR, but negative for HER2, so we applied radiation to the remaining breast and administered tamoxifen. After 9 months, local recurrence was detected and quadrantectomy with axillary lymph node dissection was performed...

With an estimated prevalence of 1 in 100 000 births, 11β-hydroxylase deficiency is the second most common form of congenital adrenal hyperplasia (CAH) and is caused by mutations in CYP11B1 Clinical features include virilization, early gonadotropin-independent precocious puberty, hypertension, and reduced stature. The current mainstay of management is with glucocorticoids to replace deficient steroids and to minimize adrenal sex hormone overproduction, thus preventing virilization and optimizing growth. We report a patient with CAH who had been suboptimally treated and presented to us at 6 years of age with precocious puberty, hypertension, tall stature, advanced bone age, and a predicted final height of 150 cm...
