Neutrophil‐to‐Lymphocyte Ratio Predicts High‐Risk Explant Features and Waitlist Survival But Is Not Independently Associated With Recurrence or Survival Following Liver Transplantation for Hepatocellular Carcinoma

We assessed the prognostic significance and the clinical stability of the neutrophil‐to‐lymphocyte ratio (NLR) before liver transplantation (LT) in a large cohort of patients with hepatocellular carcinoma (HCC) from a region with a long waitlist time. A high preoperative NLR ≥5 has been reported to predict poor outcomes following LT for HCC, and the NLR has been incorporated into several prognostic models. We evaluated 758 patients with HCC with Model for End‐Stage Liver Disease exceptions and listed for LT from 2002 to 2015 at a single LT center, of which 505 underwent LT and 253 dropped out before LT. The NLR was collected in all patients at LT and, if available, between 15 and 90 days before LT (NLR2) or at dropout. An NLR ≥5 was associated with microvascular invasion (MVI), poorer tumor differentiation, and more advanced pathology on explant. Patients with an NLR ≥5 exhibited no differences in alpha‐fetoprotein, tumor burden at listing, or number of locoregional therapies compared with patients with an NLR
