    Tamoxifen postmenopausal


    Tamoxifen is a synthetic antiestrogen with both agonist and antagonist properties. It is believed to act primarily through binding to estrogen receptors in breast cancer cells, acting as a competitive inhibitor of estrogen. Tamoxifen has a wide range of systemic effects, possibly acting on every estrogen target tissue in the body. Tamoxifen therapy is associated with a significant reduction in the risk of recurrence and death in postmenopausal women with early stage breast cancer. In addition, it has been shown to effectively suppress preclinical breast cancer, as evidenced by the decrease in second primary breast cancers in adjuvant trials. Tamoxifen is also the most widely used endocrine therapy for women with metastatic breast cancer. Tamoxifen, acting predominantly as an estrogen agonist in the liver, has generally favourable effects on serum lipids in postmenopausal women. The cytochrome P450 (CYP) enzymes 2C19, 2D6, and 3A5 are responsible for converting the selective estrogen receptor modulator (SERM), tamoxifen to its active metabolites 4-hydroxy-tamoxifen (4OHtam) and 4-hydroxy--demethyltamoxifen (4OHNDtam, endoxifen). Inter-individual variations of the activity of these enzymes due to polymorphisms may be predictors of outcome of breast cancer patients during tamoxifen treatment. Since tamoxifen and estrogens are both partly metabolized by these enzymes we hypothesize that a correlation between serum tamoxifen and estrogen levels exists, which in turn may interact with tamoxifen on treatment outcome. Here we examined relationships between the serum levels of tamoxifen, estrogens, follicle-stimulating hormone (FSH), and also determined the genotypes of CYP2C19, 2D6, 3A5, and SULT1A1 in 90 postmenopausal breast cancer patients. Tamoxifen and its metabolites were measured by liquid chromatography-tandem mass spectrometry. Estrogen and FSH levels were determined using a sensitive radio- and chemiluminescent immunoassay, respectively. We have shown an association between tamoxifen and its metabolites and estrogen serum levels.

Tamoxifen is a hormone therapy drug used to treat ER+ breast cancer in pre- and post-menopausal women. Learn about how tamoxifen works and its side. Tamoxifen therapy is associated with a significant reduction in the risk of recurrence and death in postmenopausal women with early stage breast cancer. In addition, it has been shown to effectively.

    In 2006, the large STAR clinical study concluded that raloxifene is equally effective in reducing the incidence of breast cancer, but after an average 4-year follow-up, although the difference was not statistically significant, there were 36% fewer uterine cancers and 29% fewer blood clots in women taking raloxifene than in women taking tamoxifen. Tamoxifen improves fertility in males with infertility by disinhibiting the hypothalamic–pituitary–gonadal axis (HPG axis) via ER antagonism and thereby increasing the secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH) and increasing testicular testosterone production. It is taken as a preventative measure in small doses, or used at the onset of any symptoms such as nipple soreness or sensitivity. Other drugs are taken for similar purposes such as clomifene and the anti-aromatase drugs which are used in order to try to avoid the hormone-related adverse effects. Occasionally tamoxifen is used in treatment of the rare conditions of retroperitoneal fibrosis A report in September 2009 from Health and Human Services' Agency for Healthcare Research and Quality suggests that tamoxifen, raloxifene, and tibolone used to treat breast cancer significantly reduce invasive breast cancer in midlife and older women, but also increase the risk of adverse side effects. Some cases of lower-limb lymphedema have been associated with the use of tamoxifen, due to the blood clots and deep vein thrombosis (DVT) that can be caused by this medication. Resolution of the blood clots or DVT is needed before lymphedema treatment can be initiated. Given the similar efficacy of tamoxifen and anastrozole for women older than age 60 years, decisions about treatment should be informed by the risk for serious adverse health effects and the symptoms associated with each drug. the National Surgical Adjuvant Breast and Bowel Project (NSABP) B-35 trial, performed in women who had received lumpectomy plus whole-breast irradiation, anastrozole significantly improved the breast cancer–free interval, although the benefit was limited to patients aged the IBIS-II DCIS trial, performed in women who had undergone local excision with or without radiotherapy, anastrozole was noninferior to tamoxifen in preventing overall disease recurrence. Margolese, MD, of Jewish General Hospital, Mc Gill University, is the corresponding author of the NSABP B-35 article in . (For more coverage on these two trials from the 2015 San Antonio Breast Cancer Symposium, see pages 24 and 25.) NSABP B-35 Trial In this double-blind trial, 3,104 patients from 333 sites in the United States, Canada, and Mexico were randomized between January 2003 and June 2006 to receive daily anastrozole at 1 mg (n = 1,552) or tamoxifen at 20 mg (n = 1,552) for 5 years. Reduced Recurrence With Anastrozole Median follow-up was 9.0 years, with a total of 212 breast cancer–free interval events observed. Events occurred in 90 patients in the anastrozole group vs 122 in the tamoxifen group (hazard ratio [HR] = 0.73, = .78). Five-year breast cancer–free interval rates were 96.3% in both groups, and estimated 10-year rates were 93.1% vs 89.1%. Among all events, invasive disease occurred in 43 vs 69 patients (HR = 0.62, Adverse Events Second primary cancers occurred in 107 patients in the anastrozole group vs 102 in the tamoxifen group (risk ratio [RR] = 1.04, 95% confidence interval [CI] = 0.78–1.37), with a nonsignificantly greater incidence of uterine cancer in the tamoxifen group (8 vs 17 cases, RR = 0.47, 95% CI = 0.18–1.15). Fracture was nonsignificantly more common with anastrozole (69 vs 50 patients, RR = 1.38, 95% CI = 0.95–2.03).
