Recurrence Patterns After Hepatectomy With Very Narrow Resection Margins for Hepatocellular Carcinoma.

ABSTRACT:

Background

The extent of hepatic resection In HCC depends on the remnant liver reserve or the proximity of the tumor to major vessels. In this study, we evaluated the effects of very close resection margins on postoperative recurrence.

Methods

Consecutive LR for HCC between 2003 and 2009 were studied. Patients were divided into groups with very narrow (≤1 mm) or wider (>1 mm) resection margins. Propensity score matching (PSM) was used to balance demographic, surgical, and pathological factors.

Results

983 patients were included in the study. After PSM, 173 patients were analyzed in each group. 5-year tumor recurrence and survival rates were comparable. Most recurrences were multiple intrahepatic. Section margin recurrences were similar in both groups. By multivariate
