Similarly, decrease miR-20a expression (HR = 4.281, P = 0.013; Table 3), tumor size (HR = 1.253, P = 0.014; Table 3), pre-LT serum AFP level (HR = 2.235, P = 0.028; Table 3) and micro-vascular invasion (HR = 3.643, P = 0.012; Table 3) significantly affected RFS of HCC patients following LT. The gene discussed is AFP; the disease is hepatocellular carcinoma.
