Keywords: Liver, Cancer, Carcinoma, hepatocellular; Barcelona Clinic Liver Cancer; Overall survival; Tumor burdenIn the present study of 297 patients, we evaluated the role of three-dimensional (3D) quantitative tumor burden analysis using fully automatic segmentation at magnetic resonance imaging in the subcategorization of the Barcelona Clinic Liver Cancer (BCLC) stage A hepatocellular carcinoma (HCC) after curative resection. Our results demonstrated that 3D quantitative total tumor burden (TTB) and serum a-fetoprotein were independent predictors of overall survival and could be used to subcategorize the BCLC stage A HCC. Additionally, the higher TTB (>18.5%) was correlated to more aggressive tumor behaviors (i.e., microvascular invasion and poor tumor differentiation).
