10% 12 months: 99%: 95%: 84%: 56%: 38%: 19% Notes: Prevention of breast symptoms—specifically gynecomastia and breast pain—induced by 150 mg/day bicalutamide monotherapy with tamoxifen in 282 men with prostate cancer. Bicalutamide and tamoxifen were initiated at the same time (0 months).
Tamoxifen is a pure antiestrogenic trans-isomer and has differential actions at estrogen target tissues throughout the body. Tamoxifen is selectively antiestrogenic in the breast but estrogen-like in bones and endometrial cancer. [24] Tamoxifen undergo phase I metabolism in the liver by microsomal cytochrome P450 (CYP) enzymes.
Tamoxifen is currently first-line treatment for nearly all pre-menopausal women with hormone receptor-positive breast cancer. [1] Raloxifene is another partial agonist SERM which does not seem to promote endometrial cancer , and is used primarily for chemoprevention of breast cancer in high-risk individuals, as well as to prevent osteoporosis ...
In a double-blind crossover study, patients were given either a placebo or tamoxifen (10 mg orally twice daily) for one month, in random order. Seven out of ten patients saw a reduction in gynecomastia size with tamoxifen (P < 0.005), and the overall reduction for the group was statistically significant (P < 0.01). [ 39 ]
Oral exemestane 25 mg/day for 2–3 years of adjuvant therapy was generally more effective than 5 years of continuous adjuvant tamoxifen in the treatment of postmenopausal women with early-stage estrogen receptor-positive/unknown receptor status breast in a large well-designed [citation needed] trial. Preliminary data from the open-label TEAM ...
[4] [27] (One study reported a 46-fold increased rate of MBC in trans women, i.e. gender reassignment from male to female.) A large study found that diabetes is associated with an increased risk of developing breast cancer with men having a slightly higher but significant risk than women (20.1% of all men vs. 16.5% of all women). [28]
Similarly, in the trials of 150 mg/day bicalutamide monotherapy for advanced prostate cancer, fewer than 10% of men reported decreased sex drive or reduced erectile function as a side effect. [9] About two-thirds of men in these trials, who had advanced prostate cancer and were of almost invariably advanced age, [ 10 ] maintained sexual ...
Endoxifen is an active metabolite of tamoxifen and has been found to be effective in patients that have failed previous hormonal therapies (tamoxifen, aromatase inhibitors, and fulvestrant). [3] [4] [5] The prodrug tamoxifen is metabolized by the CYP2D6 enzyme to produce endoxifen and afimoxifene (4-hydroxytamoxifen). [6]
