RESUMO
BACKGROUND: Laparoscopic liver resection (LLR) and radiofrequency ablation (RFA) represented potential treatments for patients with a single hepatocellular carcinoma (HCC) smaller than 3 cm. As the aging population soared, our study aimed to examine the advantage/drawback balance for these treatments, which should be reassessed in elderly patients. METHODS: A multicentric retrospective study compared 184 elderly patients (aged >70 years) (86 patients underwent LLR and 98 had RFA) with single ≤3 cm HCC, observed from January 2009 to January 2019. RESULTS: After propensity score matching (PSM), the estimated 1- and 3-year overall survival rates were 96.5 and 87.9% for the LLR group, and 94.6 and 68.1% for the RFA group (p = 0.001) respectively. The estimated 1- and 3-year disease-free survival rates were 92.5 and 67.4% for the LLR group, and 68.5 and 36.9% for the RFA group (p = 0.001). Patients with HCC of anterolateral segments were more often treated with laparoscopic resection (47 vs. 36, p = 0.04). The median operative time in the resection group was 205 min and 25 min in the RFA group (p = 0.01). Length of hospital stay was 5 days in the resection group and 3 days in the RFA group (p = 0.03). CONCLUSION: Despite a longer length of hospital stay and operative time, LLR guarantees a comparable postoperative course and a better overall and disease-free survival in elderly patients with single HCC (≤3 cm), located in anterolateral segments.

BACKGROUND: Optimal treatment of hepatocellular carcinoma (HCC) beyond the Milan criteria (MC) is debated. The aim of the study was to assess overall-survival (OS) and disease-free-survival (DFS) for HCC beyond MC when treated by trans-arterial-chemoembolization (TACE) or surgical resection (SR). METHOD: between 2005 and 2015, all patients with a first diagnosis of HCC beyond MC(1 nodule>5 cm, or 3 nodules>3 cm without macrovascular invasion) were evaluated. Analyses were carried out through Kaplan-Meier, Cox models and the inverse probability weighting (IPW) method to reduce allocation bias. Sub-analyses have been performed for multinodular and single large tumors compared with a MC-IN cohort. RESULTS: 226 consecutive patients were evaluated: 118 in SR group and 108 in TACE group. After IPW, the two pseudo-populations were comparable for tumor burden and liver function. In the SR group, 1-5 years OS rates were 72.3% and 35% respectively and 92.7% and 39.3% for TACE (p = 0.500). The median DFS was 8 months (95%CI:8-9) for TACE, and 11 months (95%CI:9-12) for SR (p < 0.001). TACE was an independent predictor for recurrence (HR 1.5; 95%CI: 1.1-2.1; p = 0.015). Solitary tumors > 5 cm and multinodular disease had comparable OS and DFS as Milan-IN group (p > 0.05). CONCLUSION: Surgery allowed a better control than TACE in patient bearing HCC beyond MC. This translated into a significant benefit in terms of DFS but not OS.
