- Development of an MRI-based risk scoring system (MERIS) to predict early recurrence after resection of solitary hepatocellular carcinoma (HCC) ≤5 cm.
- MERIS incorporates four MRI features: elevated aspartate aminotransferase, tumor size, nonsmooth tumor margin, and peritumoral hepatobiliary phase hypointensity.
- The system demonstrated high predictive performance with a c-index of 0.75 in both training and external test sets.
- MERIS outperformed pathologic analysis-based models and existing prognostic systems in predicting 2-year recurrence-free probabilities.
- The study suggests MERIS as a superior tool for individualized risk assessment in patients with small solitary HCC undergoing resection.
