Blueberry compound may boost cancer treatment in small trial
NCT ID NCT03671811
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This phase II trial tests whether adding pterostilbene, an antioxidant found in blueberries, to the hormone drug megestrol acetate can better slow endometrial cancer growth before hysterectomy. About 44 patients will receive either megestrol acetate alone or with pterostilbene for a short time before surgery. The main goal is to see if the combination reduces tumor cell growth more effectively.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
megestrol acetate and pterostilbene
What this could lead to
If it works, this could point toward a way to shrink endometrial tumors before surgery, possibly improving outcomes.
What could go wrong
This is a small, early-phase trial with only 44 participants, so results may not apply widely. The added benefit of pterostilbene is uncertain.
