Prognostic significance of pre-treatment neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios in non-surgically treated uterine cervical carcinoma.

The aim of the present study was to assess the prognostic significance of the pre-treatment neutrophil-to-lymphocyte ratio (NLR), the platelet-to-lymphocyte ratio (PLR) and other clinicopathological characteristics in patients with non-surgically treated uterine cervical carcinoma. The correlations of clinicopathological characteristics with overall and progression-free survival were determined in 98 Japanese patients who received non-surgical treatment for uterine cervical carcinoma between January 1997 and July 2013. Survival rates were calculated using the Kaplan-Meier method and potential prognostic indicators were assessed using a Cox proportional hazards model. A total of 68 patients (69.4%) had a high pre-treatment NLR (≥3.5) and 34 patients (34.7%) had a high pre-treatment PLR (≥212). Both NLR and PLR were found to be positively correlated with pre-treatment platelet counts. Multivariate analysis identified NLR and carcinoembryonic antigen level, but not PLR, as independent predictors of overall and progression-free survival. In conclusion, the present study identified two prognostic indicators for uterine cervical carcinoma, both of which can be easily and cost-effectively monitored via blood testing.
