Risk Model for Predicting Aggressive Recurrence of Hepatocellular Carcinoma after Microwave Ablation Using MRI and Clinical Parameters.

ABSTRACT: Purpose To develop and validate a risk score model for predicting aggressive recurrence (AR) of hepatocellular carcinoma (HCC) after microwave ablation (MWA). Materials and Methods This retrospective study included consecutive patients with solitary HCC (≤3 cm) who underwent preoperative contrast-enhanced MRI and MWA from June 2014 to October 2019. In the training set, multivariable Cox regression analysis identified clinical, laboratory, and MWA parameters and MRI features associated with AR. The resulting predictive model, named Aggressive Recurrence after Microwave Ablation (ARMA), was evaluated in the test set using the concordance index (C-index) and compared with the Barcelona Clinic Liver Cancer staging system and known risk factors. Kaplan-Meier survival curves were compared using
