[Experience with screening for colorectal carcinoma using the Haemoccult Test]

The authors submit their experience with the screening of colorectal cancer in 1985-1987 in the Bruntál district. Within the programme 9772 workers from industry and agriculture aged 45 years and more, regardless of sex, were examined. The return rate of tests was 93% and a total of 189 patients with a positive test of occult haemorrhage (1.93%) was detected. Adenomatous polyps or colorectal carcinoma were diagnosed in 91 patients (0.93%). The authors discuss demands which must be respected to make the screening successful. Attention is focused not only on the activity of health workers in this preventive programme but also to help leading workers in enterprises and the lay public. Only by coordination of the activities of all these bodies a favourable effects can be achieved.
