Abstract

Whether hepatic resection for multinodular hepatocellular carcinoma (HCC) is indicated remains to be demonstrated. We investigated the prognostic factors in a large series of patients treated with hepatic resection at a reference cancer center. All consecutive patients resected for multinodular HCC from January 2004 to April 2015 were reviewed. The study endpoints were the survival analysis and the definition of resection criteria. Among 380 patients resected for HCC, 116 (31%) were affected by multinodular HCC without macrovascular invasion. The median tumor number was 2 (range 2-30), while the median tumor size was 3.5cm (range 1.1-28). The 90-day mortality was 2.6%. Morbidity was 31%. After a median follow-up of 31months (range 3.1-149.7), the 1-, 3-, and 5-year overall survival rates were 85, 52, and 35%, respectively. At the multivariate analysis, tumor number more than 4 (HR=2.15; 95% CI 1.8-4.18; P=0.001), tumor size more than 6cm (HR=2.78; 95% CI 2.08-4.91; P=0.001), esophageal varices (HR=3.01; 95% CI 1.98-5.61; P=0.002), and major hepatectomy (HR=2.91; 95% CI 1.97-4.54; P=0.001) were independently significant for survival. Median survival shifted from 20 to 52months based on these factors. Hepatic resection for multinodular HCC may result in survival benefit for patients up to four tumors, none more than 6cm, without varices, and eventually treated by conservative surgery.
