Materials and Methods: 184 patients with unresectable HCC were enrolled from 2009 to 2011. Data were acquired through patientsu0027 medical records and follow-up. Receiver operating curves (ROC) were used to determine the optimal cut-off levels of NLR and PLR. Kaplan-Meier univariate analysis and multivariate Cox regression analysis were used to evaluate the correlation of the NLR, PLR, and other potential prognostic factors with overall survival. Results: The optimal cutoff levels were 2.5 for NLR and 105 for PLR by ROC curve analysis. Patients with NLR ≥ 2.5 and PLR ≥ 105 groups had significantly worse OS. The median survival time for patients with low NLR and high NLR were 19 months (2–35 months) and 10 months (2–34 months) respectively. And median survival time were 13 months (2–35 months) and 21 months (2–35 months) in the high and low PLR group respectively. Multivariate analysis showed that NLR ≥ 2.5 (HR, 2.41; 95% CI, 1.26–4.13; P = 0.034, PLR ≥ 105 (HR, 1.79; 95% CI, 1.17–3.41; P = 0.028), tumor ≥ 10 cm (HR, 1.81; 95% CI, 1.04–2.62; P = 0.016), BCLC C stage (HR,3.12; 95% CI, 1.72–4.98; P = 0.021) and albumin 35 u003c g/L (HR, 0.56; 95% CI, 0.34–0.95; P = 0.03) were independent risk factors for OS. Conclusions: Elevated NLR and PLR were independent factors of a poor prognosis in unresectable patients undergoing 131 I-labeled-metuximab plus TACE.
