Expression of three common serum enzymes in patients with hepatitis B related hepatocellular carcinoma

Objective To explore the clinical value of alanine aminotransferase(ALT), aspartate aminotransferase(AST) and gamma-glutamine transpeptidase(GGT) in the diagnosis of hepatitis B-related hepatocellular carcinoma, and to provide reference for clinical diagnosis. Methods From November 2015 to November 2017, 118 patients with hepatitis B-related primary liver cancer (hepatitis B-related primary liver cancer group) admitted to Tongji Huangzhou Hospital of Huazhong University of Science and Technology were selected.And 116 patients with cirrhosis (hepatocirrhosis group) and 114 healthy people were selected as control group.The levels of ALT, AST and GGT and the specificity and sensitivity of each index were compared among the three groups, and the ROC curve was analyzed. Results The levels of serum ALT, AST and GGT in the hepatitis B-related primary hepatocellular carcinoma group were higher than those in the cirrhosis group and the control group, and the above serum indicators in the cirrhosis group were higher than those in the control group[(267.1±131.5)U/L vs.(31.2±11.3)U/L vs.(17.4±4.6)U/L, (76.6±23.2)U/L vs.(45.2±13.1)U/L vs.(24.3±6.6)U/L, (125.3±42.6)U/L vs.(53.1±17.6)U/L vs.(22.4±4.4)U/L, all P<0.05]. ROC curve showed that the area under GGT curve was 0.85, under ALT curve was 0.78, and under AST curve was 0.73, the area under the combined diagnostic curve of the three indicators was 0.95.The sensitivity and specificity of three combined diagnosis were higher than those of ALT, AST and GGT. Conclusion The levels of serum ALT, AST and GGT in patients with hepatitis B-related primary liver cancer are elevated, and the combined diagnosis of the three indicators has high sensitivity and specificity, which is worthy of clinical reference.
