Chan et al. [45] constructed a preoperative model (early recurrence after surgery for liver tumor [ERASL]-pre) and a postoperative model (ERASL-post) based on gender, AFP level, MVI, tumor size, and tumor number, with AUCs ranging from 0.614 to 0.736 for the ERASL-pre and 0.653 to 0.763 for the ERASL-post in the derivation cohorts from different countries or districts. The gene discussed is AFP; the disease is neoplasm.
