Abstract：
BACKGROUND:The aim of this study was to clarify whether the types of portal vein (PV) occlusion during hepatectomy affect the long-term outcome in patients with hepatocellular carcinoma (HCC). METHODS:Eighty-six patients who had undergone curative hepatic resection for HCC were divided on the basis of the type of PV occlusion into 2 groups: total PV occlusion (TPVO, n = 56) and selective PV occlusion (SPVO, n = 30) groups. The recurrence-free survival was compared between the groups, and factors affecting recurrence-free survival were examined by univariate analyses followed by multivariate analyses. Moreover, the patients with a single nodular HCC less than 5 cm in diameter were abstracted from both groups, and the recurrence-free survival rate was compared. RESULTS:The patients and tumor-related factors were similar in the TPVO and SPVO groups. The recurrence-free survival was better in the SPVO group than in the TPVO group (median recurrence-free survival time, 1520 vs 561 days, P = .017). The type of PV occlusion was a significant factor for recurrence-free survival by univariate analysis but did not reach significance ( P = .052) by multivariate analysis. In the selected patients who had a single nodular HCC less than 5 cm in diameter, the recurrence-free survival was also significantly better in the SPVO group than in the TPVO group (median recurrence-free survival time, 2613 vs 1003 days, P = .018). CONCLUSIONS:Hepatectomy under selective PV occlusion seems to improve the recurrence-free survival in patients with HCC.
