Treatment with chemotherapy and bevacizumab, an anticancer drug, is associated with a greater risk of blood clots in patients’ arteries compared with treatment with chemotherapy only, according to a study published online August 7 in the Journal of the National Cancer Institute.The combination of chemotherapy and bevacizumab has been shown to increase survival in patients with metastatic colorectal and non–small-cell lung cancer, but some previous studies suggest these patients are at an increased risk for blood clots in their arteries.
