Clinical Relevance of Preoperative Neutrophil to Lymphocyte and Platelet to Lymphocyte Ratio in Renal Cell Carcinoma
Journal Title: JOURNAL OF UROLOGICAL SURGERY - Year 2018, Vol 5, Issue 4
Abstract
Objective: The association of preoperative neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) with postoperative tumor stage and Fuhrman nuclear grade was investigated in patients with renal cell carcinoma (RCC). Materials and Methods: Data of 123 patients, who were operated due to RCC, in our clinic was analysed. NLR and PLR were evaluated in patients who were classified according to tumor stage (T1 and T2 low stage, T3 and T4 high stage) and Fuhrman nuclear grade (grade 1 and 2 low-grade, grade 3 and 4 high-grade). NLR and PLR were compared using Levene’s test between the groups. Results: Sixty four patients were female (52.1%) and 59 were male (47.9%). All haematological parameters were expressed as 103/μL. Mean age, blood neutrophil, lymphocyte and platelet counts, and NLR and PLR values of the patients were 62.49±12.43 years, 6.27±2.8, 2.05±0.83, 263.72±89.03, 4.01±3.93, and 149.73±82.1, respectively. The most common histologic subtype was recorded as clear cell RCC (76.4%). NLR and PLR were 3.83±3.22 and 142.79±66.66, respectively in the low-stage group and 4.43±5.29 and 165.85±109.41, respectively in the high stage group. As for the Fuhrman nuclear grading, NLR and PLR were 3.81±3.45 and 146.63±87.36, respectively in the low-grade group and 4.61±5.387 and 159.32±63.42 in the high-grade group. There was no statistically significant difference between the groups (p>0.05). Conclusion: Although not statistically significant, high tumor stage and nuclear grade were positively correlated with NLR and PLR. It is concluded that, further multi-center and prospective studies with larger samples are needed to derive meaningful results.
