Abstract

AIM: To present the results of hepatectomies performed for hepatocellular carcinoma in a specialist unit and to compare the results of an initial period (1987-1993) with those obtained in a second period (1995-2000) in which the indications were limited to Child class A patients without portal hypertension. During the second period technical improvements such as intermittent selective hilar clamping and greater hiliar restrictions on transfusions were introduced. PATIENTS AND METHODS: One hundred and ten hepatectomies were performed in 105 patients with hepatocellular carcinoma in our unit over a 12-year period. Eighty percent of the tumors occurred in cirrhotic livers, mainly caused by hepatitis C virus. In the second period, upper gastrointestinal endoscopy was systematically performed to study the presence of varices. Hemodynamics studies were optionally performed to rule out portal hypertension. RESULTS: In the second period larger tumors were resected, a greater number of major hepatectomies were performed due to the increased frequency of hepatocellular carcinoma in non-cirrhotic liver, and fewer patients underwent transfusion. Early mortality was reduced from 21% to 1.8% and mean survival significantly increased from 37 to 52 months. Actuarial survival increased from 64% to 91% at 1 year and from 23% to 52% at 5 years in the first and second periods, respectively. Disease-free survival also increased significantly from 53% and 84% at 1 year and 27% and 40% at 5 years in the first and second periods, respectively. Analysis of the results in cirrhotic patients also showed a statistically significant improvement in early mortality and survival. Multivariate analysis of prognostic factors for survival demonstrated that the absence of blood transfusion, patients who underwent resection in the second period and the presence of pseudocapsules were independent factors for increased survival. CONCLUSIONS: The results of liver resection for hepatocellular carcinoma improved significantly due to the reduction in early mortality produced by more rigorous patient selection and the introduction of technical improvements.
