Surgical and Obstetric Outcomes in Endometrial Adenocarcinoma and Atypical Endometrial Hyperplasia With Conservative Treatment

This is a monocentric cohort study conducted at the CLASS Hysteroscopy Center of Fondazione Policlinico Universitario A. Gemelli IRCCS in Rome. It includes women diagnosed with endometrial adenocarcinoma (EAC) or atypical endometrial hyperplasia (AEH) who underwent conservative treatment using standardized hysteroscopic techniques performed by a single surgeon. The intervention consists of hysteroscopic lesion resection, insertion of a 52 mg levonorgestrel-releasing IUD, and in selected cases oral progestin therapy with Megestrol Acetate. The study includes both women desiring fertility preservation and patients medically unfit for radical surgery. Follow-up includes hysteroscopic biopsies at 3, 6, and 12 months. The primary objective is to assess obstetric outcomes, with secondary endpoints including oncologic outcomes.
