Effects of hysteroscopic surgery combined with progesterone therapy on fertility and prognosis in patients with early endometrial cancer and atypical endometrial hyperplasia or endometrial intraepithelial neoplasia: a meta-analysis.

ABSTRACT

OBJECTIVE: This meta-analysis aimed to evaluate the effects of hysteroscopic surgery combined with progesterone therapy on fertility and prognosis in patients with early endometrial cancer (EC), atypical endometrial hyperplasia (AEH), or endometrial intraepithelial neoplasia (EIN). METHODS: Studies on hysteroscopic surgery combined with progesterone therapy for patients with early-stage EC, AEH, or EIN were searched from Embase, Web of Science, PubMed, and Cochrane Library databases. The included studies contained one or more of the following outcome variables pregnancy rate, live birth rate, complete response (CR) rate, and recurrence rate after conservative treatment. The meta-analysis was performed using Stata. RESULTS: 13 pieces of literature containing 239 patients with EC and 199 patients with AEH/EIN were included. As per the results of meta-analysis, the pregnancy rates of EC patients and AEH/EIN patients were 49% (95% CI 33-65%) and 47% (95% CI 31-64%), respectively, and the live birth rates were 45% (95% CI 32-58%) and 44% (95% CI 34-54%), respectively. CR rates of EC patients and AEH/EIN patients were 90% (95% CI 85-94%) and 100% (95% CI 97-100%), respectively, and the disease recurrence rates were 17% (95% CI 8-28%) and 11% (95% CI 3-23%), respectively. CONCLUSION: Hysteroscopic surgery combined with progesterone was linked to an improved overall response rate, reduced disease recurrence rate, and increased pregnancy and live birth rates among patients with EC and AEH/EIN.
