To identify Neutrophil/Lymphocyte ratio(NLR) as a prognostic predictor influencing long term survival for patient undergoing radical cystectomy with different urothelial carcinoma stages
Materials and Methods:
We obtained 163 patients who admitted for urothelial carcinoma and underwent radical cystectomy during 2005-2008 in Linkou Chang-Gung Memorial Hospital. The preoperative factors including gender, tumor pathology, tumor size, pathological characteristics and pre-OP lab data were analysed. The paired t-test was used to analyze associations between categorical variables. Multivariate analysis was performed. Significance level was set at p<0.05. All stastical analysis was done with SPSS for MAC.
This study included total 163 cases with mean patient age as 66.6 years old. The most common cell type as infiltrating urothelial carcinoma and 5-year overall survival rate was 43%. We obtained pre-OP lab data for calculating NLR and set different cut points for comparing significance in different groups. When NLR was set as 3, there was significance survival difference between two groups(NLR>3, Overall Survival=45.92M; NLR<3, OS=56.62M). However, when moving on into multivariate analysis, the NLR was not an independent prognostic factor for patient receiving radical cystectomies. (HR=1.06, 95% CI=0.45-2.50, p=0.90)
In patient undergoing radical cystectomies, NLR showed overall survival difference between group when cut point was set at 3. However, further multivariate analysis failed to showed independent prognostic power of NLR in current patient cohort.
