Clinicopathologic Features of Patients With Primary Hepatocellular Carcinoma Surviving Without Recurrence More Than 10 Years After Primary Hepatic Resection

Abstract

Objective:  The aim of this study was to clarify the predictive factors of recurrence-free time more than 10 years after primary hepatic resection for hepatocellular carcinoma (HCC). Summary of background data:  Surgical resection is a curative treatment for HCC patients with hepatic functional reserve; however, the high recurrence rate must be addressed. Methods:  The study included 595 patients who had undergone curative resection for HCC. Multivariate analysis was performed to identify factors associated with recurrence-free survival at more than 10 years. Results:  Multivariate analysis revealed that tumor size ≤2 cm (P = 0.004), albumin-bilirubin (ALBI) grade 1 (P = 0.03), Fibrosis-4 (FIB-4) index ≤3.3 (P = 0.002), and histologic inflammation grade ≤1 (P = 0.03) were independent predictive factors for recurrence-free survival for more than 10 years. Predictive points were scored as follows: 2 points, tumor size ≤2 cm or FIB-4 index ≤3.3; and 1 point, ALBI grade 1 or histologic inflammation grade ≤1. Patients were divided into 3 groups according to their total points: group 1, 0 to 2 points (n = 317); group 2, 3 to 4 points (n = 239); and group 3, 5 to 6 points (n = 39). Recurrence-free survival rates among the 3 groups were significantly different (P < 0.0001). Conclusions:  Tumor size, ALBI, FIB-4 index, and histologic inflammation grade were independent predictive factors for recurrence-free survival longer than 10 years after curative hepatic resection for HCC.
