Synopsis

Keywords: Liver, CancerTo assess the predictive value of preoperative gadoxetic acid (GA)-enhanced magnetic resonance imaging (MRI) features and postoperative histopathological grading for early recurrence of hepatocellular carcinoma (HCC) without microvascular invasion (MVI) after curative hepatectomy. The results of the present demonstrated that our predictive model incorporating postoperative Edmondson-Steiner grade and preoperative imaging features including peritumoral hypointensity on HBP and RIR on HBP (Model-2) represents a promising model to assess the risk of early recurrence after resection of MVI-negative HCC. This predictive model may help clinicians formulate more aggressive and personalised treatment plans way earlier to improve patient prognosis and reduce early recurrence.
