Abstract

Aim: To study the correlation of pre-operative neutrophil to lymphocyte ratio (NLR) with pathological stage, Fuhrman grade, sarcomatoid differentiation, tumor necrosis and lymph node positivity and its prognostic role in non-metastatic renal cell carcinoma (non-mRCC).

Materials and methods: This retro-prospective, observational study was done at a tertiary care center in Mumbai, India. All patients with non-mRCC from July 2015 to April 2018 were included. Patients with co-existing systemic infection, prior immunotherapy, and long-term steroids were excluded. NLR closest to surgery, but within one month prior to surgery was used. Patients were stratified as NLR ≥ 3.0 or < 3. NLR was correlated with known prognostic factors by Pearson's correlation.

Results: 113 patients, aged 18-81 years (83 males and 30 females) were included. 75% had clear cell RCC. 62% had stage 1 disease. 58% patients had Fuhrman Grade 2. 10 patients had lymph node metastasis, 6 had sarcomatoid differentiation, 40 had tumor necrosis. The NLR was < 3 in 72 patients. Statistically significant correlation between NLR and tumor stage (p = 0.0054) as well as NLR and tumor necrosis (p = 0.0128) was shown.

Conclusions: NLR correlates significantly with higher T stage and tumor necrosis. NLR may be integrated with well-established prognostic markers to improve the accuracy of prognostic scores.

中性粒细胞与淋巴细胞比率作为非转移性肾细胞癌的预后标志物-它是否增加了我们已经知道的?

目的:探讨非转移性肾细胞癌(non-metastatic renal cell carcinoma, non-mRCC)术前中性粒细胞/淋巴细胞比值(NLR)与病理分期、Fuhrman分级、肉瘤样分化、肿瘤坏死及淋巴结阳性的相关性及其对预后的影响。材料和方法:这项回顾性、前瞻性、观察性研究是在印度孟买的一家三级保健中心完成的。2015年7月至2018年4月期间所有非mrcc患者均纳入研究。同时存在全身性感染、既往免疫治疗和长期使用类固醇的患者被排除在外。NLR离手术最近，但在手术前一个月内使用。结果:纳入113例患者，年龄18-81岁(男性83例，女性30例)。75%为透明细胞RCC。62%的人患有1期疾病。58%的患者为Fuhrman 2级。淋巴结转移10例，肉瘤样分化6例，肿瘤坏死40例。结论:NLR与较高的T分期及肿瘤坏死有显著相关性。NLR可与已建立的预后标志物相结合，以提高预后评分的准确性。
