Adjuvant endocrine treatment with medroxyprogesterone acetate or tamoxifen in stage I and II endometrial cancer--a multicentre, open, controlled, prospectively randomised trial.
Endometrial cancer is a hormone-dependent disease and therefore an adjuvant hormonal therapy might improve the outcome in the early stages of the disease. Between 1983 and 1989, we conducted a randomised trial of 388 patients who received either medroxyprogesterone acetate (MPA) (n=133) or tamoxifen (n=121) orally for 2 years, or were observed only (n=134) after surgical therapy. The aim was to evaluate whether an adjuvant treatment can improve disease-free and overall survival rates. After a median follow-up period of 56 months (range 3-199 months), we observed no differences in the disease-free and overall survival rates for the tamoxifen group compared with the control or the MPA group. Side-effects were more frequent and severe in the MPA-group than in the tamoxifen group. In patients with early endometrial cancer, adjuvant endocrine treatment did not significantly improve the outcome. However, tamoxifen did have some beneficial effects on coexisting morbidity.
