Hepatectomy for hepatocellular carcinoma with major portal or hepatic vein invasion: Results of a multicenter study

Background. The role of hepatic resection in patients with hepatocellular carcinoma (HCC) and invasion of a main portal or hepatic vein branch is controversial. We evaluated the efficacy of hepatic resection and the factors affecting survival after resection in such patients. Methods. The records of 102 patients who underwent resection for HCC with major vascular invasion between 1984 and 1999 were reviewed. Prognostic factors were evaluated by univariate and multivariate analysis. Results. The study included 87 men and 15 women. The median age was 59 years. The perioperative mortality rate was 5.9%. Median survival was 11 months (median follow-up, 93 months). The 1-, 3-, and 5-year survival rates were 45%, 17%, and 10%; the longest-living survivor was still alive at 14.8 years. Absence of moderate to severe fibrosis and absence of high nuclear grade were associated with a better 5-year survival rate (23% vs 5%; P =. 001 and 21% vs 9%; P =. 04, respectively). On multivariate analysis, moderate to severe fibrosis remained a significant predictor of both short-term (≤ 6 months) and long-term (>6 months) survival (P
