Objective This study aims to explore the feasibility of a hysteroscopic procedure combined with progestin therapy in young patients with stage Ia endometrioid carcinoma (EC) to avoid sterilization.

Materials and Methods Eleven young women with stage Ia EC (International Federation of Gynecology and Obstetrics grade 1) who were treated with a hysteroscopic approach combined with progestin from July 2004 to June 2016 were retrospectively analyzed and followed up to monitor their general recovery and pregnancy outcome.

Results The patients' median age was 27.3 years (range, 25–39 years). Comorbidities consisted of primary infertility in 8 patients, polycystic ovary syndrome in 4, uterine fibroids in 2, and diabetes in 1. The results of immunohistochemical analysis were positive for all estrogen and progestin receptors. After treatment, 9 patients attained complete remission, and 2 patients achieved partial remission. The results of peritoneal cytology in 4 patients were negative. As of this writing, 6 of the 11 patients have given birth to 7 infants, and 1 patient had an ectopic pregnancy. Two patients ultimately underwent radical resection. The average follow-up time was 82.3 months (range, 15 to 152 months), and all patients remain disease-free.

Conclusions Hysteroscopic surgery combined with progestin treatment for stage Ia EC in young patients to avoid sterilization was practical and may represent a new option for patients with stage Ia EC who wish to preserve their fertility.
