During 0 to 1 year after resection, the importance score of tumor thrombus (defined as the tumor extending into a vessel, typically portal vein) was 103.01, substantially higher than scores of other factors, such as tumor diameter (33.94), gamma-glutamyl transpeptidase (GGT) (20.25), and tumor capsule (19.22). Here, GGTLC1 is linked to neoplasm.
