BACKGROUND/AIMS: Evaluation of the short- and long-term outcome of liver resections for HCC in cirrhotic patients.
METHODOLOGY: A retrospective analysis was performed on 106 consecutive cirrhotic patients with HCC resected between June 1974 and September 2002. Univariate and multivariate analyses were performed on several clinicopathological variables to analyze factors affecting the long-term outcome and intrahepatic recurrence.
RESULTS: 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), tumor 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%. Univariate analysis showed that viral etiology of cirrhosis (p=0.03), presence of multiple nodules (p=0.02) and vascular invasion (p=0.05) are related to a worse long-term survival. Multivariate analysis showed that only the viral etiology of cirrhosis and the presence of multiple nodules were significant independent prognostic factors.
CONCLUSIONS: Results after hepatic resection for HCC in cirrhotic patients can be improved by using a limited surgical approach. The viral etiology of cirrhosis, the presence of multiple nodules and vascular invasion negatively affected recurrence rate and long-term survival.
