Aspirin has selective benefit in colorectal cancer
Patients with gene mutation appear to gain advantage from drug

The mystery of why aspirin helps some colorectal cancer patients but not others may be partially solved. A new study finds that the drug seems to extend survival in patients whose tumors harbor a specific genetic mutation, while patients lacking the mutation get no survival advantage from regularly taking the pills.
The study, in the Oct. 25 New England Journal of Medicine, may lead to standardized testing of colorectal cancer patients for the mutation, in a gene called PIK3CA, to see who w...
