Expression and Significance of Anti EZH2 Autoantibodies IgG in Hepatocellular Carcinoma Patient's Serum Samples / 现代检验医学杂志

ABSTRACT

Objective To detect the anti EZH2 autoantibodies IgG expression in hepatocellular carcinoma patient's serum samples and investigate the relationship of anti EZH2 autoantibodies IgG expression with clinicopathological parameters.Methods ELISA method was used to detect the anti EZH2 autoantibodies in serum of 120 cases of HCC patients and compared with 115 healthy controls.Results Serum anti EZH2 antibodies in patients with hepatocellular carcinoma group the content of IgG was 2.015±0.568 μg/ml group,anti EZH2 antibodies IgG content control health was 1.185±0.289 μg/ml.There was significant difference between two groups (t=12.48,P＜0.001).Anti EZH2 antibodies of IgG in serum of pa ticnts with hepatocellular carcinoma was up-regulated and the degree of tumor size,tumor the degree of differentiation,TNM grading and intrahepatic metastasis (t=8.485 ～ 57.93,P＜0.001).And age,sex,drinking,whether HBV infection had no significant difference (t=1.22～5.20,P＞0.05).Conclusion The expression of anti EZH2 autoantibodies in serum was related to the occurrence and development of hepatocellular carcinoma,and the detection of serum anti EZH2 autoantibodies in serum of liver cancer may be helpful to judge the malignant behavior and prognosis of hepatocellular carcinoma (HCC).which may be used as a refcrcnce for the evaluation of the prognosis of HCC patients with IgG antibody against IgG.
