Abstract

Currently there is no consensus as to which staging system is best in predicting the survival of patients with hepatocellular carcinoma (HCC). The aims of this study were to identify independent predictors of survival and to compare 7 available prognostic staging systems in patients with HCC. A total of 239 consecutive patients with cirrhosis and HCC seen between January 1, 2000, and December 31, 2003, were included. Demographic, laboratory, and tumor characteristics and performance status were determined at diagnosis and before therapy. Predictors of survival were identified using the Kaplan-Meir test and the Cox model. Sixty-two percent 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 censorship, 153 (63%) patients had died. The 1- and 3-year survival of the entire cohort was 58% and 29%, respectively. The independent predictors of survival were performance status (P < .0001), MELD score greater than 10 (P = .001), portal vein thrombosis (P = .0001), and tumor diameter greater than 4 cm (P = .001). Treatment of HCC was related to overall survival. The Barcelona Clinic Liver Cancer (BCLC) staging system had the best independent predictive power for survival when compared with the other 6 prognostic systems. In conclusion, performance status, tumor extent, liver function, and treatment were independent predictors of survival mostly in patients with cirrhosis and HCC. The BCLC staging system includes aspects of all of these elements and provided the best prognostic stratification for our cohort of patients with HCC.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
