Attenuation of binuclear hepatocytes in the paracancerous liver tissue is associated with short‐term recurrence of hepatocellular carcinoma post‐radical surgery

Abstract

AbstractShort‐term recurrence of hepatocellular carcinoma (HCC) after radical resection leads to dismal outcomes. To screen high‐recurrence risk patients to provide adjuvant treatment is necessary. Herein, based on our previous research, we further focused on the changes in the abundance of binuclear hepatocytes (ABH) in the paracancerous liver tissue to discuss the relationship between the attenuation of binuclear hepatocytes and postoperative short‐term recurrence, by combining with the assessment of the value of a reported independent early recurrence risk factor in HCC, protein induced by vitamin K absence or antagonist‐II (PIVKA‐II). A cohort of 142 paracancerous liver tissues from HCC patients who received radical resection was collected. Binuclear hepatocytes were reduced in the paracancerous liver tissues, compared with the liver tissues from normal donors. ABH was negatively correlated with clinical features such as tumor size, TNM stages, tumor microsatellite formation, venous invasion, and Alpha‐fetoprotein (AFP) level, as well as the expression of E2F7 and Anillin, which are two critical regulators concerning the hepatocyte polyploidization. According to the short‐term recurrence information, ABH value was laminated, and univariate and multivariate logistic regression was performed to analyze the relationship between paracancerous ABH and short‐term tumor relapse. Simultaneously, the predictive effectiveness of the ABH value was compared with the preoperative PIVKA‐II value. As observed, the paracancerous ABH value below 1.5% was found to be an independent risk factor for recurrence. In conclusion, the paracancerous ABH is a credible indicator of short‐term recurrence of HCC patients after radical resection, and regular assessment of ABH might help to prevent short‐term HCC recurrence.
