Hereditary nonpolyposis colon cancer

I am concerned that the recommendation statement from the Canadian Task Force on Preventive Health Care on colorectal cancer screening1 did not mention the need to screen people with hereditary nonpolyposis colon cancer for other types of cancer. In some kindreds with hereditary nonpolyposis colon cancer, extracolonic malignancies including endometrial, bladder, stomach and other cancers have been reported.2 It is important to mention that other surveillance measures in addition to colonoscopy should be considered for people at risk of developing hereditary nonpolyposis colon cancer;2 the article leaves the false impression that a colonoscopy is the only screening modality required in such kindreds.
