用ELISA和免疫扩散法分别检测经临床与病理确诊的86例大肠癌病人的CCA、CA19－9和IAP含量，以探讨其诊断价值。结果表明这三种标志物诊断大肠癌的敏感性分别为44％、55％、72％，特异性分别为92％、78％、67％。通过联合检测：以三项之一阳性为诊断依据时，敏感性、特异性分别为81％和88％，以三者同时阳性为依据时，敏感性、特异性分别为31％和100％。CCA特异性高，CA19－9和IAP敏感性较高，联合检测有助于大肠癌的诊断。
The levels of CCA, CA19-9, and IAP in 86 patients with colorectal cancer were determined by ELISA and immunodiffusion to determine the diagnostic value. The results showed that the sensitivity of the three markers in the diagnosis of colorectal cancer was 44%, 55%, and 72%, respectively, and the specificity was 92%, 78%, and 67%, respectively. Through joint detection: When one of the three positives was used as the diagnostic basis, the sensitivity and specificity were 81% and 88% respectively. When the three were positive, the sensitivity and specificity were 31% and 100%, respectively. The specificity of CCA is high, and the sensitivity of CA19-9 and IAP is high. Combined detection is helpful for the diagnosis of colorectal cancer.
