Background: Neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), and prognostic nutritional index (PNI), are immunonutritional indices, have been shown as an independent factor to predict postoperative recurrence and/or overall survival in patients with hepatocellular carcinoma (HCC). Aim: to validate neutrophils-to-lymphocytes ratio (NLR) as a predictor of post radiofrequency ablation recurrence of hepatocellular carcinoma (HCC). Patients and methods: This cross sectional prospective study was conducted on 50 Egyptian patients had radiofrequency ablation for HCC within Barcelona clinical liver cancer (BCLC) stage A. Pre-treatment laboratory tests and imaging were used to measure NLR, PLR, PNI, Child-Pugh (CTP score, tumor number and tumor size. HCC recurrences were followed after three month. Results: According to NLR cut-off value, the patients with NLR >1.73 had larger tumour size, and higher rates of tumor multiplicity .After 3 month follow up 30/50 (60%) patients had tumour recurrence. Regarding recurrence after RFA showed that CTP class B (P 11.74), NLR-PNI 1 group (NLR > 1.73 or PNI ≤ 11.74) and NLR-PNI 2 group (NLR > 1.73 and PNI ≤ 11.74). The patients with NLR-PNI 2 group had increase in number of portahepatis lymph node, number and size of tumor, decrease serum albumin and change in PNLR. Multivariate analyses suggested increased NLR (hazard ratio [HR] =2.09; 95% confidence interval [CI] =1.88–2.55; PConclusion: High blood NLR after RFA is a predictor for worse survival and also can predict recurrence of HCC. Higher NLR-PNI score predict a worse prognosis in patients who underwent RFA.
