Curative effects of hysteroscopic resection combined with progesterone on early-stage endometrial cancer and its prognosis.

PURPOSE

To explore the clinical efficacy of hysteroscopic resection combined with megestrol acetate in the treatment of patients with early-stage endometrial cancer (EC) and its prognosis.

METHODS

130 patients with early-stage EC were divided into two groups: MA group (hysteroscopic resection combined with megestrol acetate, n=65) and Control group (hysteroscopic resection alone, n=65). The clinical efficacy, serum carbohydrate antigen 125 (CA125) level and incidence of adverse reactions were compared between the two groups, and the patients' pregnancy status, pregnancy outcome, survival status and tumor recurrence were recorded through follow-up.

RESULTS

The curative effect was assessed in all patients after treatment. The overall response rate was 83.1% (54/65) and 65.2% (43/65), respectively, in MA group and Control group, which was significant better in MA group than that in Control group. After treatment, the serum CA125 levels markedly declined in both groups. The pregnancy rate in MA group was obviously higher than in Control group. The follow-up results revealed that the 5-year overall survival (OS) was 83.1% (54/65) and 81.5% (53/65) and the progression-free survival (PFS) was 76.9% (50/65) and 73.8% (48/65), respectively, in MA group and Control group.

CONCLUSION

Hysteroscopic resection combined with megestrol acetate has superior clinical efficacy to hysteroscopic resection alone in the treatment of patients with early-stage EC, which can greatly increase the success rate of pregnancy and reduce the serum CA125 level. However, thelong-term survival and PFS of patients had no significant differencesbetween the two treatment methods. Key words: hysteroscopic resection, megestrol acetate, endometrial cancer, early stage, curative effect.
