AFP and metastatic malignant neoplasm in the lymph nodes: Serum AFP level (P = 0.02), tumor size (P<0.001), tumor number (P<0.001), portal vein invasion (P<0.001), hepatic vein invasion (P<0.001), tumor differentiation (P<0.001), and distant organ (P = 0.016) and lymph node metastasis (P<0.001) were identified as independent risk factors of survival after resection by multivariate analysis.
