[Costs and benefits of screening for colorectal tumors using the Hemoccult test in asymptomatic individuals 45-60 years of age].

Screening of colorectal tumours by the Haemoccult test (HT) in asymptomatic subjects aged 45-60 years makes it possible to assess the diagnosis of colorectal carcinoma (CR-CA) in two-thirds of the affected subjects in Dukes stage A and B, as compared with one third of symptomatic patients of the same age group. The mean diagnostic and therapeutic costs related to the relative incidence of individual stages of Dukes staging of CR-CA in screened asymptomatic individuals and symptomatic patients are approximately equal. The analysis is not concerned with costs of care after surgical and supplementary treatment which are considerable in subjects with the advanced form of the disease.
