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%.
本文讨论了隐血试验（检测粪便中的潜血）在大规模筛查过程中诊断大肠肿瘤的可靠性。对1573名45岁及以上的健康受试者进行了检查。在参与检测的1190名受检者中，24人（2%）结果呈阳性，58人（4.9%）结果可疑。在23名（95.9%）检测呈阳性的受检者中发现了肿瘤：癌症——12.5%，息肉——54.2%，绒毛状肿瘤——29.2%。隐血试验在大规模筛查中证明是有用的。由于该试验的应用，无症状直肠癌的诊断率为0.2%，绒毛状肿瘤为0.6%，单个腺瘤性息肉为1.1%。
