To the Editor.
—The review article by Moore and LaMont1 on colorectal cancer was well done, but I should like to comment on several points.First, the statement that salicylates should not be taken during stool blood testing should be modified. Aspirin, 1,300 mg/day is advised for many older patients who have transient ischemic attacks.2 These patients probably need not interrupt aspirin therapy to perform stool blood testing, as this dose of aspirin has not been found to cause positive fecal blood tests.3Second, Winawer's name was misspelled. This error deserves correction, as he has contributed immensely to the early detection of colorectal cancer.Finally, I was interested in the authors' estimate of the cost of evaluating a positive stool blood test. Roberts and I4 have precisely determined these expenses. In 1978 to 1980, we screened 1,986 patients, using the stool blood test at a cost
