Prognostic nomogram for predicting recurrence-free survival in patients with hepatitis B virus-related hepatocellular carcinoma with high preoperative serum GGT levels. The nomogram contains 10 rows. The variables, including AFP, HBV-DNA, satellite nodules, microvascular invasion, and tumor pathological grade, are presented on rows 2 to 6, and each variable is given a score identified by the scale on row 1. The total points of an individual patient are calculated by adding the score of all five variables and is located on the total point axis (row 7). The estimated 2-, 3-, or 5-year probabilities of RFS of the individual patient will be acquired from the nomogram (row 8 to 10) according to their total points. RFS, recurrence-free survival; HCC, hepatocellular carcinoma; AFP, α-fetoprotein; GGT, γ-glutamyl transpeptidase.
