摘要
Objective This study aimed to review the available literature on fertility-preserving treatment and pregnancy outcomes in patients with early-stage endometrial carcinoma who desired to preserve their fertility. Data sources The PubMed database （1992-2012） was searched for the words ＂conservative ＂OR＂ fertility sparing ＂OR＂ fertility preserving＂ AND ＂endometrial neoplasms＂ （MESH）. All relevant articles in English and the relevant references were collected. Study selection Data from published articles about fertility-preserving treatment of endometrial cancer, including the response and recurrence rate of conservative treatment, strategies of infertility treatment, pregnancy, and obstetric outcomes, were selected. Data were mainly extracted from 41 studies, which are listed in the reference section of this review. Results Hormone therapy was the most common method used for early-stage endometrial carcinoma in patients who wished to preserve fertility. Sixty percent of the patients became pregnant after remission of the carcinoma. The percentage of patients who conceived in the assisted reproductive technology group was higher than that of the natural pregnancy group （80.0% vs. 43.2%, P〈0.01）. A higher rate of preterm labor and multiple pregnancies was observed in the assisted reproductive technology group than that in the natural pregnancy group. The majority of pregnancies （71.4%） in the assisted reproductive technology group were achieved by in vitro fertilization-embryo transfer. The clinical pregnancy rate of transfer cycles in patients with endometrial carcinoma was 34.1%. Conclusions Assisted reproductive technology is a good option in well-selected patients with early-stage endometrial carcinoma who have completed conservative treatment. In vitro fertilization-embryo transfer offers an opportunity to achieve an immediate pregnancy.
