目的 探讨大肠癌术前血清ＣＥＡ、ＣＲＰ联合检测的临床价值。方法 对２９７例大肠癌患者测定其ＣＥＡ、ＣＲＰ，从病理分期、癌肿部位和手术方式方面进行研讨。结果 联合检测的总阳性率为９０．５７％，明显高于单项检测者；两项阳性者与手术方式有密切关系；右半结肠癌与左半结肠癌、直肠癌的ＣＲＰ阳性率和均值相比，差异明显。结论 术前血清ＣＥＡ、ＣＲＰ联合检测具有显著的互补性和临床实用价值。
Objective To explore the clinical value of combined detection of preoperative serum CEA and CRP in colorectal cancer. Methods 297 patients with colorectal cancer were evaluated for CEA and CRP. The pathological stage, location of cancer and surgical methods were studied. Results The total positive rate of the combined detection was 90.57%, which was significantly higher than that of the individual testers. The two positive cases were closely related to the surgical approach; the CRP positive rate and mean value of the right colon and left colon and rectal cancer were positive. The difference is obvious. Conclusion The combined detection of preoperative serum CEA and CRP has significant complementarity and clinical practical value.
