Is this trial a fit for you?

Likely a good fit

Ideal candidates include women with early endometrial carcinoma or atypical endometrial hyperplasia who wish to preserve their reproductive function.

Probably not a fit

Patients with acute liver disease, renal dysfunction, or those who are pregnant or have a confirmed diagnosis of any reproductive system cancer may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study aims to develop a prediction model for progesterone sensitivity in patients diagnosed with early endometrial carcinoma or atypical endometrial hyperplasia. After diagnosis via hysteroscopy, eligible patients will receive daily doses of Medroxyprogesterone acetate or Megestrol acetate, with regular evaluations through hysteroscopy every three months. The study will analyze patient-derived tumor-like cell clusters to assess lipid content and construct a predictive model based on the collected data from 148 cases. The model will then be validated to determine its effectiveness in predicting treatment responses.

Why it matters

Potential benefit: If successful, this study could help tailor progesterone treatments for patients with early endometrial cancer, potentially improving fertility preservation outcomes.

How similar studies have gone: While similar predictive models have been explored, this specific approach using patient-derived tumor-like cell clusters is relatively novel.
