RESUMO
ABSTRACT Purpose: To evaluate the importance of preoperative neutrophil lymphocyte ratio (NLR) predicting malignancy in patients who undergo partial nephrectomy due to renal mass. Materials and Methods: Seventy nine patients who underwent open partial nephrectomy for renal masses were included in this retrospective study. In preoperative routine blood tests, renal ultrasonography and contrast-enhanced computed tomography were performed for all patients. Preoperative neutrophil lymphocyte ratio were compared in patients with clear cell renal cell carcinoma (Group1, 65 patients) and benign lesions (Group 2, 14 patients). The predictive ability of NLR was analyzed by ROC curves and Youden Index method was used to identify the cut-off value for NLR. Results: The mean age of patients was 59.8±11.7 years in Group1 and 57.4±12.6 years in Group 2 (p=0.493). The mean tumor size was 3.8±1.2 cm in Group 1 and 3.3±1.0 cm in Group 2 (p=0.07). The median NLR was 2.48 (1.04) in Group 1 and 1.63 (0.96) in Group 2 (p<0.001). The area under a ROC curve was 0.799 (p<0.001). Conclusions: Preoperative neutrophil lymphocyte ratio may predict renal masses that can not be distinguished radiologically. Our results must be confirmed by large and properly designed prospective, randomized trials.

ABSTRACT Purpose: The aim of this study was to evaluate the relationship between tumor size and grade with visceral adipose index (VAI) levels in patients with renal cell carcinoma. Materials and methods: We retrospectively reviewed the records of 310 consecutive patients with RCC who underwent radical nephrectomy at our institution between January 2007 and May 2014. VAI was calculates for males and females seperately as this formula like previous study. The relationship between tumor size and nuclear grade with VAI levels were evaluated statisticaly. Analyses were completed using Chi-square tests and Logistic regression analysis. Results: Among the 310 total patients analyzed in our study, there were 176 males (56.8%) and 134 females (43.2%). VAI levels were statistically higher in men and women with high tumor size (p<0.001). VAI levels were statistically higher in men and women with high fuhrman grade (p<0.001). Conclusions: The components of VAI may have effect on tumor carcinogenesis in similar pathways. In our study patients with high VAI levels were found to have statistically significant higher nuclear grade and tumor size. VAI can be a useful index for the evaluation and calculation of renal cell cancer aggressiviness. Further studies with more patients are needed to confirm our study.

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.
