Prediction of microvascular invasion based on pre-transplant alpha-fetoprotein concentration, number of tumors, and size of the largest tumor was associated with AUROCs of 0.603 (SE = 0.046), 0.661 (SE = 0.042), and 0.622 (SE = 0.045), respectively (Fig. 1a,b, and c). This evidence concerns the gene AFP and neoplasm.
