AFP and metastatic malignant neoplasm in the lymph nodes: AFP level (HR = 1.514, 95%CI = 0.995 − 2.304), lymph node metastasis (HR = 2.004, 95%CI = 1.083 − 3.708), treatment option (HR = 0.649, 95%CI = 0.423–0.0.996), and ECOG 2/0 (HR = 9.397, 95%CI = 2.750 − 32.107) were potential risk factors for PFS (Table 3).
