Fertility-preserving treatment of stage IA, well-differentiated endometrial carcinoma in young women with hysteroscopic resection and high-dose progesterone therapy

Objective: The standard treatment for endometrial cancer is surgery with hysterectomy. However, this procedure will cause infertility in young women who desire to preserve pregnant ability. Conservative management with hormone therapy has been shown to be satisfactory in both tumor control and fertility preservation. Recently, hysteroscopic tumor resection followed by progestin therapy has been reported to be an alternative strategy. In this study we present our experience with this approach. Materials and methods: Six young patients (30-36 years old) diagnosed with grade 1 stage IA endometrial cancer who wished to preserve fertility were enrolled for this treatment procedure. The patients underwent hysteroscopic tumor resection followed by oral progestin therapy with either megestrol acetate or medroxyprogesterone acetate for at least 6 months. Interval hysteroscopy with biopsy was performed during the treatment course to evaluate disease response. Results: All of the six patients had complete tumor remission after hysteroscopic resection and progestin therapy (five in 6 months, one in 9 months). In a median follow-up of 32 months (range 4-49months), one patient became pregnant spontaneously and delivered a full-term healthy baby via cesarean section. She received a definite surgery 3 months later, and the pathology confirmed no tumor existence. The other five patients were also free of disease at the last follow-up. Conclusion: Hysteroscopic tumor resection followed by progestin therapy for early-stage and well-differentiated endometrial cancer is a safe conservative treatment strategy. It could be an option for young patients who wish to preserve fertility. (C) 2018 Taiwan Association of Obstetrics & Gynecology. Publishing services by Elsevier B.V.
