Hepatic resections for hepatocellular carcinoma (HCC): short and long-term results on 106 cirrhotic patients

Abstract

To evaluate the short and long term outcome of liver resections for hepatocellular carcinoma in cirrhotic patients. A retrospective analysis was performed on 106 consecutive cirrhotic patients with hepatocellular carcinoma resected between June 1974 and September 2002 at the Department of Surgery "Pietro Valdoni" - University of Rome "La Sapienza" and at the Liver and Multivisceral Transplant Unit of the University of Modena. Univariate and multivariate analyses were performed on several clinicopathological variables to analyze factors affecting the long-term outcome and intrahepatic recurrence. Overall mortality and morbidity were 10.7% and 26% respectively. These rates significantly decreased in the last years: from 1997 to 2002 no hospital mortality has been recorded. After a median follow-up of 19 months (interquartile range: 10-36), tumour recurrence appeared in 25 patients (23,5%). The 1-, 3-, and 5-year overall survival rates were 86,6%, 70,3%, and 60,6%, respectively. The 1-, 3-, and 5-year disease-free survival rates were 86,3%, 58,1%, and 40,7%. On univariate analysis, viral ethiology of cirrhosis (p=0.03), presence of multiple nodules (p=0.02) and vascular invasion (p=0.05) were found to be related to a worse long-term survival. At the multivariate analysis only the viral ethiology of cirrhosis and the presence of multiple nodules were confirmed as indipendent prognostic factors. Early results after hepatic resection for HCC can be improved by using a limited surgical approach. The viral ethiology of cirrhosis, the presence of multiple nodules and vascular invasion negatively affected recurrence rate and long-term survival.
