Abstract:
Objective To evaluate clinical significance of the CEA, CA19-9, CA242, AFP, CA724,SCC, TPA, TPS combined detection for the clinical diagnosis of gastrointestial cancer. Methods 373 cases of upper digestive tract malignant tumor patient and 50 cases of healthy serum sample were detected for eight markers, evaluating the relationship between the level of markers and illness. Results 8 marker diagnostic positive rates were: CEA 26.80 %, CA19-9 27.34 %, CA242 34.14 %, AFP 2.84 %, SCC 19.72 %, CA724 12.13 %, TPA 34.15 %, TPS 30.89 %. The total positive rate of joint detection of 8 markers was 89.05 %.Preoperative CEA, CA242, SCC-positive patients had a shorter survival time. CA242 and CA19-9 levels with upper gastrointestinal malignancies were positively correlated. Conclusion The combined detection of a number of markers in different pathological type and clinical staging is statistically significant, and the positive rate is much higher than any single marker test results. CA19-9 and CA242 may be the best combination of monitoring the disease. CA724, CA242 and SCC can be as adverse prognostic indicators for cardia, stomach,esophageal malignant tumors, respectively.
