[Results of screening for colorectal carcinoma in the Bruntál District using the Haemoccult Test 1985-1986].

In the Bruntál district in 1985-1986 in 11,046 working people aged 45-69 years an examination for occult haemorrhage into faeces was made, using the Haemoccult test. The return rate of the tests was 92.05%. Screening detected 241 patients (2.18%) with positive tests in faeces, who were subjected to further examinations. In 129 patients (1.17%) one or more adenomatous polyps or adenocarcinoma of the large intestine was proved. Adenocarcinoma was detected in 15 (0.13%), eight times in stage Dukes A, twice Dukes B, three times Dukes C and twice Dukes 2. Treatment involved endoscopic polypectomy or surgical operation. Tre elaborated screening programme of colorectal carcinoma for a low risk group of asymptomatic subjects above 45 years of age helps to detect less advanced stages of this oncological affection.
