Fertility-preserving treatment in young women with well-differentiated endometrial carcinoma and severe atypical hyperplasia of endometrium.

A retrospective study on 25 women (8 with endometrial carcinoma, 17 with severe endometrial atypical hyperplasia) under 35 years treated with progestin showed that six cases (75%) in the endometrial carcinoma (EC) group and 17 (100%) in the atypical hyperplasia (AH) group responded to the treatment, and among the 14 complete responders, 4 (40%) patients with AH had 7 pregnancies and 3 healthy deliveries. Given accurate pretreatment assessment, progestin therapy is a feasible management option to preserve fertility for young women with well-differentiated endometrial carcinoma or severe atypical hyperplasia of endometrium.
