Abstract

Background: Eastern data highlight the oncological benefits of the anterior approach (AA) during right hepatectomy (RH) for hepatocellular carcinoma (HCC). However, to our knowledge, previous western data on this topic are scarce. In this study, the oncological outcomes of AA and classical approach (CA) during RH for HCC were compared.

Methods: A retrospective inverse propensity score-weighted fashion (IPTW) case-control study was performed in two French hepatobiliary surgery departments. Overall survival (OS), disease-free survival (DFS), and early recurrence rate (within 2 years after surgery) were analyzed.

Results: Survival analysis was performed for 114 patients (CA group,60 patients; AA group, 54 patients). Before IPTW adjustment, the 3-year DFS rates were 29.4% (AA group) and 44% (CA group), respectively. No significant differences were found in DFS (HR = 1.1, 95%CI:0.62-1.9, p = 0.77) and OS (HR = 1.2, 95%CI:0.54-2.6, p = 0.66). After IPTW, DFS and OS analyses showed no differences between the two groups (p = 0.77 and p = 0.46, respectively). Early recurrence rates were similar before and after IPTW. Satellite nodules were the only significant independent risk factor for recurrence.

Conclusion: AA and CA did not result in significant differences in DFS, OS, or early recurrence after right hepatectomy for HCC before and after IPTW.
