大便隐血试验如能检出息肉间变和息肉癌变,则可供大肠癌普查的初筛工具。1978年我们曾报导用邻联甲苯胺试纸在海宁红旗公社1030名社员中查出直肠息肉患者大便隐血阳性的占61％,其中伴有腺上皮间变Ⅰ—Ⅲ级患者大便隐血试验均为阳性。为了进一步探讨大便隐血检查对发现早期大肠癌及癌前病变的价值,我们于1980年1月在海宁庆云公社永安共和二大队结合大肠癌普查对30岁以上的男女社员用纸片法又进行了一次大便隐血试验,在受检者
If the fecal occult blood test can detect polyposis and polyposis, it can be used as a screening tool for colon cancer screening. In 1978, we reported that 61% of patients with rectal polyposis were found to be positive for occult blood in patients with rectal polyps in the Hongqi Commune of Haining County with o-tolidine test strips. Among them, patients with grade I-III of glandular epithelial metastases were positive for fecal occult blood tests. . In order to further explore the value of the fecal occult blood test in the detection of early colorectal cancer and precancerous lesions, we conducted a paper screening of men and women aged over 30 on the Colon Cancer General Survey of the Yongan Republican Second Brigade of Haining Qingyun Commune in January 1980. A fecal occult blood test was performed on the subject.
