The phosphatidylinositol 3-kinase signaling pathway plays an important role in carcinogenesis.12 Mutations in PIK3CA can be found in approximately 15 to 20 percent of colorectal cancers.13-19 Up-regulation of PI3K enhances PTGS2 prostaglandin and activity E2 synthesis, resulting in inhibition of apoptosis in colon-cancer cells.20 Aspirin might suppress cancer-cell growth and induce apoptosis by blocking the PI3K pathway.21 We therefore hypothesized that the result of aspirin on survival among individuals with mutated-PIK3CA colorectal cancers might differ from the impact among those with wild-type PIK3CA tumors. To test this hypothesis, we used two U.S.Don’t pick at outdated scarring.
