Patients with cirrhosis by hepatitis C virus infection treated with β-blockers (BB) have been shown to have a reduced incidence of hepatocellular carcinoma (HCC). Also, an association between propranolol therapy and lower incidence of other tumors has been described.
To analyze the incidence of HCC according to BB treatment in cirrhosis of any cause.
PATIENTS AND METHODS:
Cirrhotic patients included in the program for early detection of HCC were followed. Patients' data were prospectively registered, including transplantation and death. Patients were classified as chronically taken or not BB and the proportions of patients who remained free of tumor from the diagnosis of cirrhosis until the end of follow-up were compared using Kaplan-Meier analysis and the Breslow test.
A total of 173 patients (73 treated and 100 untreated BB) were followed. The median duration of follow-up was 11 years. There were no differences between both groups in the overall survival, number of deaths, or liver transplant.Overall, 28 patients developed HCC during the follow-up, 20 patients who were untreated and eight patients treated with BB. The cumulative proportion of cases of HCC between untreated and treated with BB from the diagnosis of cirrhosis was statistically significant (6 vs. 3%, at 5 years; 19 vs. 6% at 10 years; 24 vs. 16% at 15 years; P=0.048). Multivariate analyses showed BB intake as the only significant variable associated with the development of HCC.
Cirrhotic patients treated with BB have a lower cumulative probability of developing HCC during the 10 years after the diagnosis of cirrhosis.
