Is the Cancer of the Liver Italian Program system an adequate weighting for survival of hepatocellular carcinoma? Evaluation of intrascore prognostic value among 36 subgroups

Abstract

Different prognostic weighting of four predictive factors caused intrascore heterogeneity. Lower CLIP scores were associated with increased differences in intrascore. In conclusion, the CLIP staging scoring system is a reasonable ordinal scale, but the clinician must be aware of the heterogeneity of mortality risk within a given score.
