Statin use has been associated with a reduced incidence of colorectal cancer, and might also affect survival of patients diagnosed with colon cancer. Statins are believed to inhibit Ras signaling, and also activate the bone morphogenetic protein (BMP) signaling pathway in colorectal cancer cells. We investigated the effects of statins on overall survival of patients with a diagnosis of colon cancer, and whether their effects were associated with changes in KRAS or the BMP signaling pathways.
