Abstract

Objective: In this study, we aimed to evaluate the effects of pre-nephrectomy Neutrophil-Lymphocyte ratio (NLR) on development of distant metastasis and disease specific survival (DSS). Materials and Methods: The data of 780 patients who underwent radical or partial nephrectomy for localized renal cell carcinoma (RCC) between January 1995 and December 2014 was evaluated retrospectively. The demographics, pathologic stage, histological type of tumor, tumor grade were recorded. Furthermore, data of white blood cell, platelet, neutrophil, lymphocyte counts and NLR (level within 14 days before nephrectomy) were recorded. Primary endpoints of this study were distant metastasis development and DSS. Results: For all patients mean age was 58.4±12. During median 44 months follow-up period, distant metastasis developed in 210 (26.9%) patients and death occurred due to RCC in 132 (16.9%) patients. High NLR levels (NLR>=4) were related to higher Fuhrmann tumor grade, advanced tumor stage, distant metastasis development and disease specific mortality (for all comparisons p<0.001). On multivariate analysis, Fuhrmann tumor grade 3-4, pathological stage 3-4 and NLR>=4 were found as independent predictive factor to predict metastasis development. To predict DSS, pathological stage 3-4 and NLR>=4 were found as independent predictive factor. Conclusion: High NLR associated with high risk of metastasis development and DSS. However, multicenter and prospective trials are needed to support our results.

Özet

Amaç: Nefrektomi öncesi bakılan Nötrofil-Lenfosit Oranının (NLO) değerinin uzak metastaz ve hastalığa özgü sağ kalım (HÖS) üzerine olan etkisinin değerlendirilmesi amaçlanmıştır. Gereç ve Yöntem: Ocak 1995- Aralık 2014 tarihleri arasında lokalize Renal Hücreli Kanser (RHK) ön tanısı ile radikal veya parsiyel nefrektomi yapılan ve patolojisi RHK gelen 780 hastanın verileri retrospektif olarak değerlendirildi. Tüm hastalardan demografik, patolojik evre, histolojik tip, tümör derecesi gibi verilerinin yanında nefrektomiden 14 gün önce bakılan serum beyaz küre, platelet sayısı, nötrofil, lenfosit sayısı ve NLO oranları kaydedildi. Çalışmadaki birincil amaç NLO'nın uzak metastaz gelişimi ve HÖS ile ilişkisinin incelenmesi idi. Bulgular: Tüm hastalarda ortalama yaş 58.4±12 idi. Ortanca 44 aylık takip süresi boyunca 210 (%26,9) hastada uzak metastaz gelişirken 132 (%16.9) hastada hastalık nedeniyle ölüm gerçekleşmiştir. Yüksek NLO'nın (NLO>=4) yüksek fuhrmann tümör derecesi, ileri tümör evresinin metastaz gelişimi ve hastalığa bağlı ölüm ile ilişkili olduğu saptandı (Tüm karşılaştırmalar için p<0.001). Çok değişkenli analizde Fuhrmann tümör derecesinin 3-4 olması, patolojik evrenin 3-4 olması ve NLO'nın 4 ve üzeri olması metastaz gelişimini öngören bağımsız prediktif faktör olduğu saptandı. HÖS açısından ise patolojik evrenin 3-4 olması ve NLO'nın 4 ve üzeri olmasının bağımsız prediktif faktör olduğu saptandı. Sonuç: Yüksek NLO, metastaz gelişim riski ve HÖS ile ilişkili olduğu saptanmıştır. Ancak çalışmamızın sonuçlarını destekleyen çok merkezli ve prospektif çalışmalara ihtiyaç bulunmaktadır.
