Long-Term Outcomes of Laparoscopic Anatomical versus Non-Anatomical Liver Resection for Hepatocellular Carcinoma.
Objective: The objective of this study was to investigate the long-term outcomes between laparoscopic anatomical liver resection (LAR) and laparoscopic non-anatomical liver resection (LNAR) in patients with hepatocellular carcinoma (HCC).
Methods: In this single-center retrospective cohort study, 1773 patients, from January 2009 to December 2017, were assessed for inclusion. After exclusions, 661 patients were included: 304 patients received LAR and 357 patients received LNAR. Propensity score matching (PSM) with 1:1 ratio was used to eliminate the selection bias between LAR and LNAR groups. The Kaplan-Meier and Cox models were used for survival analysis.
Results: After PSM, 250 patients were in LAR or LNAR group, respectively. The overall survival (OS) had no significant difference between LAR and LNAR by Kaplan-Meier analysis. While, LAR had better disease-free survival (DFS) compared with LNAR (Log-rank P=0.035). The cumulative 5-year DFS rates were 48% for LAR, and 38% for LNAR. By Cox analysis, LAR was an independent risk factor of DFS (HR=1.308, P=0.030). In subgroup analysis for tumor size ≤ 5 cm, 207 patients were in LAR or LNAR subgroup after PSM. LAR had better DFS compared with LNAR (Log-rank P=0.033). LAR was an independent risk factor of DFS (HR=1.333, P=0.036). The cumulative 5-year DFS rates were 50% for LAR, and 39% for LNAR. In another subgroup analysis for tumor size > 5 cm, 43 patients were in LAR or LNAR subgroup after PSM. The DFS had no significant difference between LAR and LNAR (Log-rank P=0.912).
Conclusion: LAR is preferred for HCC patients with tumor size ≤5cm compared with LNAR because of the better DFS. For patients with tumor size >5cm, LAR and LNAR might be alternative procedures with comparable long-term outcomes.
