Laparoscopic versus open hepatectomy for hepatocellular carcinoma with cirrhosis: a single-center propensity score matching analysis.

Background: Laparoscopic hepatectomy (LH) for hepatocellular carcinoma (HCC) remains controversial due to limited research. This study analyzed the oncology prognosis of patients who received LH treatment for HCC compared with conventional open hepatectomy (OH).

Methods: We conducted a retrospective analysis of patients with cirrhosis who underwent hepatectomy for HCC between 2012 and 2018. Patients were divided into LH and OH groups, and the oncology outcomes were compared before and after 1:1 propensity score matching (PSM).

Results: A total of 403 patients with HCC cirrhosis who received LH (n=112) and OH (n=291) were enrolled. After PSM, 106 pairs of patients were matched. Compared with OH before and after PSM, there was no significant difference in overall survival (OS) and relapse-free survival (RFS) between the two groups. Tumor stage, Child-Pugh classification, venous tumor thrombus, tumor size ≥5 cm, and microvascular invasion (MVI) were independent risk factors for postoperative OS in HCC patients with cirrhosis. Tumor size ≥5 cm and MVI were independent risk factors for RFS.

Conclusions: Patients with HCC who underwent LH had a similar OS and RFS compared with those who received traditional open surgery. Therefore, LH can be used as a safe and feasible treatment for patients with HCC.
