[The crypto-hem test in screening for colon cancer].
The paper discusses the reliability of crypto-hem test (detection of occult blood in feces) in diagnosing large bowel tumors in the course of a mass screening. 1573 healthy subjects aged 45 years and older were examined. The results were positive in 24 (2%) out of 1190 screenees who were involved in the test and in 58 (4.9%) subjects the results were suspicious. Tumors were detected in 23 (95.9%) test-positive screenees: cancer--12.5, polyps--54.2 and villous tumor--29.2%. Crypto-hem test proved instrumental in mass screening. Due to its application, symptom-free rectal cancer was diagnosed in 0.2, villous tumor--0.6, and single adenomatous polyps--1.1%.
