About

To explore the treatment efficacy of megestrol acetate plus rosuvastatin in patients with early endometrial carcinoma (EEC) seeking for conservative treatment.

Full description

After diagnosed of EEC by hysteroscopy, patients meet the study criteria will be enrolled. Age, height, weight, waist circumstances, blood pressure, basic history of infertility and blood pressure will be collected. Blood tests, including fasting blood glucose (FBG), fasting insulin (FINS), OGTT 2h blood glucose and insulin, blood lipids, SHBG, sex hormone levels, anti-müllerian hormone(AMH), creatine kinase(CK) and renal/liver function tests will be performed before treatment to evacuate their basic conditions. Each subject will receive body fat testing by Inbody 520.

Patients will receive MA (megestrol acetate) 160 mg by mouth daily plus rosuvastatin 10mg by mouth daily for at least 6 months. Then hysteroscopy will be used to evaluate the endometrial condition every 3 months, and intra-operative findings will be recorded. Complete response (CR) is defined as the reversion of endometrial atypical hyperplasia to proliferative or secretory endometrium; partial response (PR) is defined as regression to hyperplasia with or without atypic; stable disease (SD) is defined as the persistence of the disease; and progressive disease (PD) is defined as the appearance of higher pathological progression, or myometrial invasion, or extra-uterine metastasis. Continuous therapies will be needed in PR or NR. Patients with PD will be recommended for hysterectomy.

Due to personal reasons, patients may not accept hysteroscopic evaluation every three months, then the longest duration will be 8 months. For patients remained SD after 6 to 8 months of treatment but refused hysterectomy, a multiple disciplinary discussion would be held for individual case, and alternative treatment would be given.

Two months of maintenance treatment will be recommended for patients with CR, and participants will be followed up for 2 years.
