Serum IgG autoantibodies against p53, CTAG1A, and TIF1 gamma, as well as IgA autoantibody against TIF1 gamma, present diagnostic value for early HCC, with anti-p53-IgG being a preferable biomarker. The panel comprised of four autoantibodies might contribute to early HCC diagnosis.
Background: Autoantibodes against tumor-associated antigens (TAAs) have been recommended for the early diagnosis of malignancies. In this study, we intend to comprehensively evaluate the performances of four autoantibodies including anti-p53, CTAG1A, TIF1 gamma-IgG and anti-TIF1 gamma-IgA for the early diagnosis of hepatocellular carcinoma (HCC), and then determine an optimal panel of autoantibodies for early HCC diagnosis. Methods: The performances of four autoantibodies were evaluated by enzyme-linked immunosorbent assay (ELISA) for the early diagnosis of HCC with 380 retrospective serum samples. A training set comprised of 92 patients with early HCC, 72 patients with hepatic benign lesions (HBL), and 86 healthy controls (HC) was used to develop the predictive model for early HCC. And then, data obtained from an independent validation set was applied to evaluate and validate the predictive model to distinguish the early HCC from the controls (HBL + HC). Results: The results of the training set showed the levels and positive rates of four autoantibodies in early HCC group were significantly higher than that in HBL group/HC group (P < 0.01), of which anti-p53-IgG exhibited the highest AUC of 0.679, with 33.7% sensitivity at 93.7% specificity; the panel comprised of four autoantibodies showed the highest AUC for the patients with early HCC, up to 0.814 (95%CI 0.760-0.860), with 72.8% sensitivity at 84.2% specificity among all possible combinations of four autoantibodies. Additionally, this fourautoantibody panel showed the AUC of 0.824, 70.8% sensitivity at 84.2% specificity in the validation set. Conclusions: Serum IgG autoantibodies against p53, CTAG1A and TIF1 gamma, and IgA autoantibody against TIF1 gamma present the diagnostic value for early HCC, of which anti-p53-IgG is a preferable biomarker. The panel comprised of four autoantibodies might contribute to early HCC diagnosis.
