大肠癌占西方国家常见肿瘤的第二位,英格兰和威尔士每年有16500人死于此病.在过去20年中生存率没什么变化,1959年时5年生存率为24%,1975年为30%。目前人群中筛选结肠癌的方法是用粪便潜血试验。即用一种浸渗愈创木酚的滤纸进行试验(潜血试验),现已广泛在美国和西德采用。本文介绍了被随机分成试验组和对照组的20525名45～75岁病人的粪便潜血试验结果。已知有肠道疾患或癌症史及医生认为不合适的病人被排除本试验.
Colorectal cancer accounts for the second most common tumor in Western countries. There are 16,500 deaths in England and Wales every year. There has been no change in survival rates in the past 20 years. The 5-year survival rate was 24% in 1959 and 30% in 1975. . The current method of screening for colon cancer in the human population is the fecal occult blood test. That is, a test (occult blood test) using a filter paper impregnated with guaiacol has been widely adopted in the United States and West Germany. This article describes the fecal occult blood test results of 20,525 patients 45 to 75 years old who were randomly assigned to a test group and a control group. Patients who are known to have a history of bowel disease or cancer and which the doctor considers inappropriate are excluded from the trial.
