Abstract
- Background: Fertility preserving therapy using medroxyprogesterone acetate (MPA) is an important option for young patients with endometrial cancer or atypical endometrial hyperplasia (AEH). However, the effectiveness and feasibility of repeated MPA therapy for patients with intrauterine recurrence following initial MPA therapy is controversial. Only a few single-institution retrospective studies have been conducted on repeated MPA therapy, therefore, multicenter prospective studies for repeated MPA therapy are highly needed. The aim of this study is to assess whether repeated MPA therapy is effective and feasible for patients with intrauterine recurrence following initial MPA therapy.<br />Methods: This is a prospective, single-arm, a multicenter phase II trial on repeated MPA therapy for intrauterine recurrence following fertility-preserving therapy for AEH or stage IA (the International Federation of Gynecology and Obstetrics [FIGO] 2008) non-myoinvasive endometrioid carcinoma grade 1. Patients are treated with oral MPA (500-600 mg/day). Pathologically assessment via dilation and curettage will be performed every 2 months until complete response. The major inclusion criteria are 1) intrauterine recurrence of AEH or stage IA (FIGO 2008) endometrioid carcinoma grade 1 without myometrial invasion or extrauterine spread confirmed by imaging tests after complete remission with the previous MPA therapy. 2) The number of recurrences should be up to twice. 3) histologically diagnosed as AEH or endometrioid carcinoma grade 1, 4) 20-42 years of age, and 5) strong desire and consent for fertility-sparing treatment. The primary endpoint is 2-year recurrence-free survival rate. A total of 115 patients will be enrolled from multiple institutions in Japan and Korea within 4 years and followed up for 2 years.<br />Trial Registration: Japan Registry of Clinical Trials Identifier: jRCTs031200256.<br />Competing Interests: No potential conflict of interest relevant to this article was reported.<br /> (© 2024.
