Avastin and Blood Clotting

Chemotherapy patients taking the popular cancer drug Avastin more likely to develop blood clots in the veins according to a Journal of the American Medical Association study released this week. Researchers found that patients combining Avastin with chemotherapy treatment raise their risks for clots by about a third.

The study of 8000 patients demonstrates “a significant increased risk with Avastin for patients while they are taking chemotherapy,” said Dr. Shenhong Wu of Stony Brook University Cancer Center in New York
Avastin’s package insert contains warnings about the potential for arterial clotting.
