Abstract

Background/Aim: Hepatocellular carcinoma (HCC) is the most common primary liver tumor and the second leading cause of cancer-related deaths worldwide. The current study aimed to investigate the clinical relevance of the epidermal growth factor-like domain multiple 6 (EGFL6) expression in HCC and to evaluate whether the expression of EGFL6 in HCC has diagnostic and prognostic significance. Patients and Methods: This study aimed to investigate EGFL6 protein expression levels in 260 HCC tissue specimens using immunohistochemical analyses. The immunohistochemical study demonstrated strong EGFL6 expression in the cytoplasm of non-tumor or normal hepatocytes. Results: The findings revealed that 98 patients exhibited low EGFL6 expression, while 162 patients displayed high EGFL6 expression. We explored the associations between cytoplasmic EGFL6 expression and the clinicopathological features of HCC. Decreased cytoplasmic EGFL6 expression exhibited significant correlations with worse cellular differentiation, higher T classification, vascular invasion, higher stage, and tumor recurrence. Survival analyses, using Kaplan–Meier survival curves for HCC patients, revealed that those with reduced cytoplasmic EGFL6 expression experienced significantly worse disease-free survival (DFS) and disease-specific survival (DSS). Univariate and multivariate analyses identified EGFL6 as an independent predictor for decreased expression, differentiation grade, vascular invasion, stage, or recurrence in cases of DFS or DSS in HCC. Conclusion: This study represents, to the best of our knowledge, the first investigation into the expression of EGFL6 protein in HCC. Taken together, our findings strongly suggest that EGFL6 likely plays a crucial role in the pathogenesis of HCC and indicates that targeting EGFL6 could be a promising therapeutic strategy.
