Abstract:

Objective To systematically evaluate the relationship between the expression of human epidermal growth factor receptor-2 (HER-2) and clinicopathologic featurests in hepatocellular carcinoma (HCC). Methods Case-control studies regarding the expression of HER-2 in HCC were searched from PubMed, CNKI, Wanfang database and VIP database from establishment of the database to May 2023. Literature screening, data extraction and risk-of-bias assessment were independently performed by two researchers. Meta-analysis was performed using Revman5.3 software. Results Thirty one case-control studies representing 2558 patients were included. Meta-analysis showed that the positive rate of HER-2 in HCC cases was significantly higher than that in control cases (54.3% vs 50.5%, O R=1.87, 95% C I: 1.13-3.10, P=0.01). The expression of HER-2 in HCC cases in age ( O R=0.48, 95% C I: 0.25-0.94, P=0.03), differentiation degree( O R=2.61, 95% C I: 1.84-3.69, P<0.01), tumor diameter ( O R=1.93, 95% C I: 1.25-2.98, P=0.003), blood metastases ( O R=5.42, 95% C I: 3.15-9.31, P<0.01), clinical stage ( O R=2.02, 95% C I: 1.39-2.94, P=0.0003), portal vein invasion ( O R=1.73, 95% C I: 1.11-2.72, P=0.02) and serum HBsAg ( O R=2.22, 95% C I:1.55-3.18, P<0.01) were statistically significant. Conclusion HER-2 is differentially expressed in HCC, and its expression level is related to clinicopathological features of HCC, suggesting a important role in the pathogenesis of HCC, and which can provide a higher level of evidence for the diagnosis and molecular targeted therapy of HCC in the future. However, the evidence for its quantity and quality remains limited, the results need to be verified by more high-quality studies.
