Objective: The objective of the study was to evaluate the regression, relapse, and live birth rates of early-stage endometrial cancer (EC) and atypical complex hyperplasia (ACH) with fertility-sparing treatment.
Study design: This was a metaanalysis of the proportions from observational studies with a random-effects model and a meta-regression to explore for heterogeneity.
Results: Thirty-four observational studies, evaluating the regression, relapse, and live birth rates of early-stage EC (408 women) and ACH (151 women) with fertility-sparing treatment. Fertility-sparing treatment for EC achieved a pooled regression rate of 76.2%, a relapse rate of 40.6%, and a live birth rate of 28%. For ACH the pooled regression rate was 85.6%, a relapse rate of 26%, and a live birth rate of 26.3%. Twenty women were diagnosed with ovarian cancer (concurrent or metastatic) during follow-up (3.6%) and 10 progressed to higher than stage I EC (1.9%) from which 2 women died.
Conclusion: Fertility-sparing treatment of EC and ACH is feasible and selected women can satisfy their reproductive wishes.
