- Abstract
- There is increasing evidence that systemic inflammation markers like neutrophil (NLR) and platelet-to-lymphocyte ratios (PLR) may play a role in the outcome of hepatocellular cancer (HCC). Between January 1994 and March 2012, 181 patients with HCC were registered on the transplant waiting list: 35 (19.3%) patients dropped out during the waiting period and 146 (80.7%) patients underwent liver transplantation (LT). The median follow-up of this patient cohort was 4.2 years (IQR: 1.8-8.3). On c-statistics, the last NLR (AUROC = 67.4; P = 0.05) was the best predictor of dropout. The last PLR had an intermediate statistical ability (AUROC = 66.1; P = 0.07) to predict post-LT tumor recurrence. Patients with a NLR value >5.4 had poor 5-year intention-to-treat (ITT) survival rates (48.2 vs. 64.5%; P = 0.02). Conversely, PLR better stratified patients in relation to tumor-free survival (TFS) (80.7 vs. 91.6%; P = 0.02). NLR is a good predictor for the risk of dropout, while PLR is a good predictor for the risk of post-LT recurrence. Use of these markers, which are all available before LT, may represent an additional tool to refine the selection criteria of HCC liver recipients.
