Currently there is no consensus which staging system is best in predicting the survival of patients with hepatocellular carcinoma (HCC). The aims of this stud y were to identify independent predictors of survival and to compare 7 available prognostic staging systems in patients with HCC. A total of 239 consecutive pat ients with cirrhosis and HCC seen between January 1, 2000, and December 31, 2003 , were included.Demographic, laboratory, and tumor characteristics and performan ce status were determined at diagnosis and before therapy.Predictors of survival were identified using the Kaplan-Meir test and the Cox model. Sixty-two perce nt of patients had hepatitis C, 56%had more than 1 tumor nodule, 24%had portal vein thrombosis, and 29%did not receive any cancer treatment. At the time of c ensorship, 153 (63%) patients had died. The 1-and 3-year survival of the enti re cohort was 58%and 29%, respectively. The independent predictors of surviv- al were performance status (P< .0001),MELD score greater than 10 (P = .001), p ortal vein thrombosis (P=.0001), and tumor diameter greater than 4 cm (P = .001) . Treatment of HCC was related to overall su- rvival. The Barcelona Clinic Liver Cancer(BCLC) staging system had the best in dependent predictive power for survival when compared with the other 6 prognosti c systems. In conclusion, performance status, tumor extent, liver fun- ction, and treatmentwere independent predictors of survival mostly in patients with cirrhosis and HCC. The BCLC staging system includes aspects of all of thes e elements and provided the best prognostic stratification for our cohort of pat ients with HCC.
