Study Summary

This phase II trial studies how well megestrol acetate with or without pterostilbene works in treating patients with endometrial cancer undergoing hysterectomy. Drugs used in chemotherapy, such as megestrol acetate, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Pterostilbene is an antioxidant found in blueberries or grapes, and it has been shown to be effective in killing tumor cells and reducing cancer burden. It is not yet known whether giving megestrol acetate with or without pterostilbene may work better in treating patients with endometrial cancer.

Primary Outcome

Ki-67 represents a specific nuclear marker for cell proliferation that is measured by staining with specific antibodies by immunohistochemical (IHC) staining. The Ki-67 proliferation index is defined as percent tumor cells staining positive, and measured on a continuous scale of 0-100%, with higher values indicating higher proliferation. Ki-67 hotspot values were assessed at two time-points during this study, prior to treatment with megace +/- pterostilbene (pre-treatment), and following complet
