Summary

This trial is testing megestrol acetate, with or without pterostilbene, to see if it can treat endometrial cancer.

Who is the study for?
This trial is for women with endometrial cancer or complex atypical hyperplasia who are fit enough for surgery (ECOG 0-2) and have normal liver and kidney function. They must be able to swallow pills, not pregnant, without serious heart conditions, infections needing IV treatment, HIV, hepatitis B/C, recent thromboembolism/stroke/MI or taking certain supplements.
What is being tested?
The study is testing the effectiveness of megestrol acetate (a chemotherapy drug) with or without pterostilbene (an antioxidant found in blueberries/grapes) in patients undergoing hysterectomy for endometrial cancer. It aims to determine if adding pterostilbene improves outcomes.
What are the potential side effects?
Megestrol acetate can cause weight gain, increased blood sugar levels, and possible risk of blood clots. Pterostilbene's side effects aren't well-known but may include mild digestive issues based on its antioxidant properties.
