As summarized in Supplementary Table 2, high NET1 expression was found to be associated with large tumor size (P = 0.011), high alpha-fetoprotein (AFP) level (P = 0.015), micro metastasis (P = 0.004), portal vein tumor thrombus (PVTT, P = 0.025) and histologic evidence of microvascular invasion (P = 0.025). This evidence concerns the gene NET1 and neoplasm.
