All of the patients were treated with combined oral MPA (500 mg/d)/LNG-IUS, and follow-up dilatation and curettage were performed every 3 months.Results A total of 5 patients were included in the study. The mean age was 30.4 ± 5.3 years (range, 25–39 years). After a mean treatment duration of 11.0 ± 6.2 months (range, 6–18 months), complete response (CR) was shown in 3 of the 5 patients, with partial response (PR) in the other 2 patients. One case of recurrence was reported 14 months after achieving CR. This patient was treated again with combined oral MPA/LNG-IUS and achieved CR by 6 months. The average follow-up period was 44.4 ± 26.2 months (range, 12–71 months). There were no cases of progressive disease. No treatment-related complications arose.Conclusions Combined oral MPA/LNG-IUS treatment is considered to be a reasonably effective fertility-sparing treatment of grade 2 stage IA endometrial cancer. Although our results are encouraging, it is preliminary and should be considered with experienced oncologists in well-defined protocol and with close follow-up. %U https://ijgc.bmj.com/content/ijgc/27/4/738.full.pdf
