The Effect of Tamoxifen on the Endometrium | Cancer Network Since the initial report by Killackey et al [1] suggesting a possible link between tamoxifen use and the development of endometrial carcinoma in three patients, approximately 133 additional cases of tamoxifen-associated uterine cancer have been reported [2-13]. Uterine serous carcinoma and endometrial intraepithelial carcinoma Postmenopausal status, hypertension, obesity could all be considered as risk factors for carcinomatous transformation within endometrial polyps in women without a history of breast carcinoma and Tamoxifen treatment. Pathology of Gynecologic Cancer | Tamoxifen and Endometrial Cancer First, endometrial cancer will be reviewed, including endometrioid carcinoma, the most common subtype, as well as less com-mon entities such as serous and undifferentiated carcinoma and MMMT. Tamoxifen-associated endometrial cancer as well as Lynch syndrome Endometrial Carcinoma Can Develop in Patients on Tamoxifen Therapy Several recent reports of possible association between tamoxifen treatment and endometrial pathologies, such as endometrial hyperplasia, endometrial polyps, adenomyosis, endometrial carcinoma and endometrial sarcoma are of concern to the clinicians. In Vitro Growth Regulation of Endometrial Carcinoma Cells by The growth inhibitory effects of medroxyprogesterone acetate (MPA) and tamoxifen (TAM) were tested on three long-established endometrial carcinoma cell lines (HEC-1, KLE, and RL95-2) and on UM-EC-l, a new endometrial carcinoma cell line established in our laboratory. Tamoxifen and Uterine Cancer - ACOG In standard dosages, tamoxifen may be associated with endometrial proliferation, hyperplasia, polyp formation, invasive carcinoma, and uterine sarcoma. Most studies have found that the increased relative risk of developing endometrial cancer for women taking tamoxifen is two to three times The Endometrial Thickness changes in Tamoxifen-Treated Tamoxifen and endometrial neoplasia.

Type I endometrial carcinomas occur most commonly before and around the time of menopause.

Endometrial carcinomas are traditionally divided into two types: Type 1: includes endometrioid

and risk factors The main risk factor for endometrioid
endometrial carcinoma is an excess of endogenous or exogenous estrogen without adequate opposition by a progestin (eg, postmenopausal estrogen therapy without a progestin). Other risk factors include
