Acetylsalicylic acid was recently shown to inhibit the development of colorectal adenomas in subjects with a moderately increased risk for colorectal cancer. The mechanisms by which acetylsalicylic acid and other NSAIDs, including COX-2 inhibitors, exert this effect include: inhibition of COX-2, induction of apoptosis and induction of the P21 protein that controls the development of crypt cells. For the majority of the population, a healthy lifestyle and healthy eating habits are the best means of preventing colorectal cancer. In addition, population-wide screening should be encouraged. For people with an increased risk of colorectal cancer, acetylsalicylic acid only has a partial effect and therefore endoscopic surveillance is still indicated. Sulindac or celecoxib may be useful for patients with familial adenomatous polyposis and in particular for inhibiting the development of rectal adenomas after subtotal colectomy with ileorectal anastomosis. However, in these cases endoscopic surveillance is also still necessary.
