Avastin is an up-an-coming cancer drug that has been applauded for increasing the survival rate among patients with different types of cancer. But researchers at Stony Brook University pooled together data from about 8,000 different patients taking the drug in 15-clinical trials and discovered an increase in blood clots.
They found patients taking Avastin had a 30-percent increased risk for developing blood clots than those not taking the drug. The highest risk was seen in patients with colorectal cancer.
Avastin may still be the right drug for some patients, but the study suggests doctors and patients need to consider these findings in determining the best course of treatment.
