Value of Combined Detection of Serum CEA, CA72-4, CA19-9 and TSGF in the Diagnosis of Gastric Cancer %K Gastric cancer %K Tumor marker %K carbohydrate antigen 72-4 %K carcino-embryonic antigen %R %X Background: To explore whether combined detection of serum tumor markers (CEA, CA72-4, CA19-9 andTSGF) improve the sensitivity and accuracy in the diagnosis of gastric cancer (GC). Materials and Methods: Anautomatic chemiluminescence immune analyzer with matched kits were used to determine the levels of serumCEA, CA72-4, CA19-9 and TSGF in 45 patients with gastric cancer (GC group), 40 patients with gastric benigndiseases (GBD group) hospitalized in the same period and 30 healthy people undergoing a physical examination.The values of those 4 tumor markers in the diagnosis of gastric cancer was analyzed. Results: The levels ofserum CEA, CA72-4, CA19-9 and TSGF of the GC group were higher than those of the GBD group and healthyexamined people and the differences were significant (P<0.001). The area under receiver operating characteristic(ROC) curves for single detection of CEA, CA72-4, CA19-9 and TSGF in the diagnosis of GC was 0.833, 0.805,0.810 and 0.839, respectively. The optimal cutoff values for these 4 indices were 2.36 ng/mL, 3.06 U/mL, 5.72 U/mL and 60.7 U/mL, respectively. With combined detection of tumor markers, the diagnostic power of those 4indices was best, with an area under the ROC curve of 0.913 (95%CI 0.866~0.985), a sensitivity of 88.9% anda diagnostic accuracy of 90.4%. Conclusions: Combined detection of serum CEA, CA72-4, CA19-9 and TSGFincreases the sensitivity and accuracy in diagnosis of GC, so it can be regarded as the important means for earlydiagnosis. %U https://journal.waocp.org/article_30752_a38465f64e4a5c3f11bdea16421b2294.pdf
