Evaluation of the prognostic value of Okuda, Cancer of the Liver Italian Program, and Japan Integrated Staging systems for hepatocellular carcinoma patients undergoing radiotherapy

Conclusions: Among the systems studied, the TNM staging approach appeared to be the best predictor of prognosis. Staging systems that reflect liver disease status (Okuda stage, CLIP, and JIS score) showed limitations in stratifying patients undergoing radiotherapy into different prognostic groups.
