Tamoxifen, sold under the brand name Nolvadex among others, is a selective estrogen receptor modulator used to prevent breast cancer in women and men. [13] It is also being studied for other types of cancer. [13] It has been used for Albright syndrome. [14] Tamoxifen is typically taken daily by mouth for five years for breast cancer. [14]
As of 2014, approximately 320,000 women are diagnosed with endometrial cancer worldwide each year and 76,000 die, making it the sixth most common cancer in women. [3] It is more common in developed countries, where the lifetime risk of endometrial cancer in women is 1.6%, compared to 0.6% in developing countries. [16]
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. [1]
Toremifene has been shown to be compatible with tamoxifen, and in 1996 it was approved for use in the treatment of breast cancer in postmenopausal women. [ 36 ] Raloxifene originally failed as a breast cancer drug due to its poor performance in comparison to tamoxifen in the laboratory [ 19 ] but the estrogenic effects of raloxifene on bone led ...
But in the new study, which included data for about 1,500 Black patients, more than 11% of those with endometrial cancer (24 of 210 people) had endometrial thickness measurements that fell within ...
One of the largest breast cancer prevention studies ever, [2] it included 22,000 women in 400 medical centers in the United States and Canada. [3] [4] [5] The study concluded that raloxifene caused fewer side-effects and less endometrial cancer than tamoxifen.
Endometrial cancer is the most common cancer of the human female genital tract. Asherman's syndrome , also known as intrauterine adhesions , occurs when the basal layer of the endometrium is damaged by instrumentation (e.g., D&C ) or infection (e.g., endometrial tuberculosis ) resulting in endometrial sclerosis and adhesion formation partially ...
N-Desmethyltamoxifen (developmental code name ICI-55,548) is a major metabolite of tamoxifen, a selective estrogen receptor modulator (SERM). [1] [2] N-Desmethyltamoxifen is further metabolized into endoxifen (4-hydroxy-N-desmethyltamoxifen), which is thought to be the major active form of tamoxifen in the body.
