Liver resection versus radiofrequency ablation in octogenarian patients for hepatocellular carcinoma: a propensity score multicenter analysis.

ABSTRACT

BACKGROUND: Liver resection (LR) and radiofrequency ablation (RFA) are considered curative options for hepatocellular carcinoma (HCC). The aim of this study was to compare outcomes after LR and RFA in octogenarian patients with HCC. MATERIALS AND METHODS: This multicenter retrospective study included 102 elderly patients (> 80 years old) treated between January 2009 and January 2019, who underwent LR or RFA for HCC (65 and 37 with, respectively). RESULTS: After Propensity Score Matching, the postoperative course of LR was burdened by a higher rate of complications than RFA group (64% vs 14%, respectively, p 0.001). The LR group had also significantly longer operative time (207 ± 85 min vs 33 ± 49 min, p < 0.001) and postoperative hospital stays than the RFA group (7 d vs 2 d, p = 0.019). Overall survival at 1-, 2-, and 3-year were 86%, 86%, and 70% for the LR group and 82%, 64%, and 52% for the RFA group (p = 0.380). Disease-free survival at 1-, 2-, and 3-year were 89%, 74%, and 56% for the LR group, and 51%, 40%, and 40% for the RFA group (p = 0.037). CONCLUSION: Despite a higher rate of Dindo-Clavien I-II post-operative complications, a longer operative time and length of hospital stay, LR in octogenarian patients can provide comparable 90d mortality than RFA and better long-term outcomes.
