Summary
Brief summary (as posted)
Given the early literature available and its biological plausibility as an inhibitor of the mammalian target of rapamycin (mTOR) protein, it is hypothesized that women with endometrial cancer who take metformin for non-cancer related reasons have a lower cancer recurrence rate compared to women not taking metformin. The primary goal of this study is to determine whether metformin use is associated with a decrease in the rate of endometrial cancer recurrence. Secondary objectives are to assess whether women with endometrial cancer taking metformin have longer progression free survival and overall survival than those that do not take metformin.
