Abstract

Background: Centrally located large hepatocellular carcinoma (HCC) is a difficult issue in surgery. These HCCs can be treated by hemi-/extended or central hepatectomies. The aim of this study was to analyze the results of hemi-/extended and central hepatectomies.

Methods: One hundred and four patients with centrally-located large tumors were retrospectively reviewed. Patients were divided into group 1 (n = 41) with hemi-/extended hepatectomies, and group 2 (n = 63) with central hepatectomies. Characteristics were analyzed between groups and survival rates were calculated.

Results: Parenchyma resection was limited in group 2. The resection margin in 92.6% of group 2 patients was < 1 cm, compared with 78.9% of group 1 patients (p = 0.056). The 1- and 5-year disease-free survival rates were 50% and 38.9% for group 1, and 50% and 15% for group 2 (p = 0.279). The 1-, 5-year overall survival rates were 89.5% and 66.2% for group 1 and 87.5% and 53.1% for group 2 (p = 0.786). Cirrhosis, the preoperative aspartate aminotransferase (AST) level and lower resected liver weight were independent factors impairing survival.

Conclusion: Hemi-/extended and central hepatectomies have comparable complication rates and long-term survival rates for patients with centrally located large HCC. Cirrhosis, the AST level and resected liver weight were independent factors determining long-term survival.
