All patients were followed-up to determine whether and where cancer recurrence developed. Excluding 4 patients who died of postoperative complications, our liver perfusion chemotherapy was performed on 27 patients. The other 67 patients did not receive this treatment. Since then, further positive and supportive results have been obtained in an additional investigation. TI - Colorectal cancer screening.
Colorectal cancer occurs throughout the world.
Little is known about the etiology of this disease, however, adequate data exist to recommend secondary prevention with mass screening of average risk asymptomatic people age 50 or over. Three randomized controlled trials of a guaiac test for fecal occult blood involving over 250,000 participants found significant reductions in colorectal cancer mortality from both annual and biennial screening. Results from observational studies are consistent with the results from the randomized trials. Therefore, a screening recommendation for a fecal occult blood testing can be justified based on the overwhelming scientific evidence. A compelling argument can be made to use an immunochemical rather than guaiac test, since data suggests that immunochemical tests may be more sensitive and more specific than guaiac tests.
