The following significant predictors of microvascular invasion were identified in univariable analyses: number of tumors (p < 0.001), size of the largest tumor (p = 0.004), total tumor volume (p = 0.005), pre-transplant alpha-fetoprotein concentration (p = 0.013), and poor tumor differentiation (p = 0.050, Table 2). Here, AFP is linked to neoplasm.
