Abstract
To summarize the pregnant rate of patients with early endometrial carcinoma and severe atypical hyperplasia after fertility-preserving treatment and analyze their pregnancy-relating factors. Endometrial curettage was used to evaluate the therapy response of endometrium after every 3 months of administration of high-dose progestin as fertility-sparing treatment for 51 patients with stage I endometrial carcinoma or severe endometrial atypical hyperplasia from Jun. 1996 to Jan. 2010. Individualized maintained treatment was given to patients after achieving complete remission of the endometrium. Pregnant results and pregnancy-relating factors were analyzed retrospectively. The median age of all the 51 patients was 29 years old. Forty-five (88%, 45/51) achieved complete response. Of the 34 cases who desired to conceive after complete response, 16 of them had 22 pregnancies, the pregnant rate was 47% (16/34); and 12 women obtained healthy live birth baby, the fertility rate was 35% (12/34). The pregnant rate of patients at age >35 or ≤ 35 was 0/2 and 50% (16/32) respectively (P > 0.05). The pregnant rate of patients with or without infertility was 40% (8/20) and 8/14, with endometrial cancer or severe atypical hyperplasia was 40% (10/25) and 6/9, respectively (all P > 0.05). The pregnant rate of patients who received in vitro fertilization-embryo transfer, ovulation promotion, or no treatment was 7/7, 6/16 and 3/11 respectively (P < 0.01). Fertility-preserving treatment for early endometrial cancer and severe atypical hyperplasia with high-dose progestin could achieve higher response rate. Assisted reproductive technologies could significantly increase the chance of conception.
