Abstract
BACKGROUND: Laparoscopic treatment for hepatocellular carcinoma (HCC) has increased. We retrospectively compared the perioperative and long-term oncological outcomes of laparoscopic liver resection (LLR) with those of open liver resection (OLR) for hepatocellular carcinoma (HCC) in well-matched patient groups using propensity score matching (PSM). METHODS: We reviewed medical records of patients with HCC who underwent liver resection between July 2007 and April 2016 at our center. In total, 2335 patients were included in this study and divided into LLR (n = 264) and OLR (n = 2071) groups. For group comparisons, 1:2 PSM was used with covariates of baseline characteristics, including tumor characteristics and surgical liver resection procedures. RESULTS: After PSM, there were 217 and 434 patients in the LLR and OLR groups, respectively. The LLR group had shorter hospital stays (8.9 vs. 14.8 days; P < 0.001) and lower postoperative morbidity (6.5% vs. 12.0%; P = 0.022). The 1-, 3-, and 5-year overall survival rates were 98.1%, 87.0%, and 78.6%, respectively, for the LLR group, and 98.3%, 90.8%, and 84.3%, respectively, for the OLR group (P = 0.570). The 1-, 3-, and 5-year disease-free survival rates were 81.0%, 62.0%, and 49.1%, respectively, for the LLR group, and 85.3%, 64.7%, and 56.2%, respectively, for the OLR group (P = 0.563). CONCLUSIONS: Long-term oncological outcomes were comparable between LLR and OLR for selected patients. LLR was associated with multiple benefits, even for selected patients with cirrhosis who underwent major hepatectomy. LLR for HCC performed by an experienced surgeon could be considered a safe and feasible alternative to OLR for selected patients.
