ABSTRACT
ABSTRACT Introduction: We investigated the prognostic significance of the neutrophil-to-lymphocyte ratio on tumor stage and Fuhrman nuclear grade in renal cell carcinoma. Methods: The records of 432 patients with RCC who underwent radical or partial nephrectomy between 2005 and 2014 were retrospectively reviewed. Patients were classified as group lower tumor stage(T1 + T2) and higher(T3 + T4). As like tumor stage, Fuhrman nuclear grade were classified lower (G1+G2) and higher(G3+G4) too. The best NLR cut off value was 3.01. Two sample t-test or Mann–Whitney U-test used for the continuous variables and a chi-square test or Fisher's exact test used for the categorical variables. Results: Among the 432 total patients analyzed in our study, there were 275 males (63.7%) and 157 females (36.3%). Mean laboratory values were CRP 2.73 ± 1.93 mg/dL (normal less than 0.3), neutrophil count 4,23 ± 1.46/μL, lymphocyte count 1,61 ± 0,61/μL and NLR 2.64 ± 1.24. According to our data, statistically pretreatment NLR significantly correlated with CRP (p<0.0001). And tumor patologic stage (p=0.08), tumor histologic grade (p<0.001) was significantly associated with NLR. Discussion: We compared the relationship of preoperative NLR and NC parameters with RCC tumor stage and grade. And NLR were found to have statistically significant higher T stage and grade at RCC. Further studies with more patients are needed to confirm our study.
