Introduction: The aim of our present study was to investigate the impact of the pretreatment neutrophil-to-lymphocyte ratio (NLR) on the antitumour effects of targeted agents in patients with metastatic renal cell carcinoma (mRCC).Methods: The NLRs in 283 cases of molecular targeted therapy for mRCC were measured before starting the prescription of the molecular targeted agent. The significance of pretreatment NLR on the site of metastatic organs and on progression-free survival (PFS)in each case was analyzed.Results: Metastases other than lung, which is defined as “extrapulmonary metastasis,” were observed in 190 cases (67.1%). The median of pretreated NLR was 2.39 (0.49‒68.7). In 97 of the 283 cases,pretreated NLR was 3.0 or higher. These cases were categorized as the high NLR group and the rest as the low NLR group. When the cases with extrapulmonary metastasis were investigated and classifiedbased on their pretreated NLR, 50% PFS in the high NLR and low NLR groups was 6.7 months and 12 months (p=0.0001), respectively. Multivariate analysis revealed that high NLR (>3.0) was an independent predictive factor for PFS in the cases with extrapulmonary metastasis (hazard ratio 2.762; p<0.0001), while there was no significant difference between PFS in the high and low NLR groups in cases with no extrapulmonary metastasis (p=0.3457).Conclusions: Our data indicate that the predictive significance of the NLR in mRCC cases involving targeted therapy depends on the metastatic organs. NLR is an independent predictive factor of PFS in cases of mRCC with extrapulmonary metastasis treated with targeted therapy.

404 Background: The neutrophil to lymphocyte ratio (NLR) is a marker of inflammation. We evaluated whether NLR is independently prognostic when adjusted for the International mRCC Database Consortium (IMDC) model and evaluated change in NLR ("NLR conversion") as a predictive marker of response to targeted therapy. Methods: A total of 5,227 metastatic renal cell carcinoma (mRCC) patients treated with targeted therapy were included; 1,199 patients in the training cohort from the IMDC and 4028 patients as the validation cohort from pooled prospective randomized controlled trials involving targeted therapy. NLR was examined at initiation of first-line targeted therapy and at 6 weeks after. The prognostic role of NLR and NLR conversion on overall survival (OS) and progression free survival (PFS) was assessed using Cox regression models adjusting for IMDC prognostic score. Results: Median baseline NLR was 3.4 and 2.9 in the training and validation cohorts, respectively. NLR >3.0 at baseline was independently associated with OS and PFS in both the training and validation cohorts (Table). A decrease in NLR by week 6 was associated with longer OS (21.1 vs. 9.7 months; HR 0.57, p<0.001), PFS (8.8 vs. 4.6 months; HR 0.54, p<0.001), and higher objective response rates (35% vs. 13%, p<0.001) compared to patients without a decrease. A rise in NLR showed opposite effects for all three endpoints. These findings were also confirmed in the validation set. Conclusions: NLR is an independent prognostic factor after controlling for IMDC criteria. NLR conversion can be an early biomarker of benefit to targeted therapy. [Table: see text]

490 Background: Two randomized trials demonstrated survival benefits associated with cytoreductive nephrectomy (CN) for metastatic renal cell carcinoma (mRCC) in the interferon era. However, the role of CN in the era of targeted therapies is yet to be defined. In recent years, neutrophil-to-lymphocyte ratio (NLR) has emerged as a clinically useful prognostic marker in several cancers including mRCC. In this multi-center retrospective study, we aim to assess the impact of CN in mRCC and the value of NLR in risk stratification and patient selection. Methods: Patients with de novo mRCC diagnosed between 2006 and 2012 from three large Australian hospitals were identified using an electronic database. Data regarding clinicopathological features, MSKCC risk group, NLR at the time of metastatic diagnosis, treatments received and survival were collected. NLR ≥5 was used as the cutoff for statistical analyses. Survival analyses were performed using the Kaplan-Meier method and compared using the log-rank test. Multivariate analyses used the Cox proportional hazards method. Results: Our study identified 91 de novo mRCC patients. CN was performed in 46 (51%) patients. Patients who underwent CN were more likely to be younger (median age 59.0 vs. 64.6, p=0.019), and to have received systemic therapy post CN (91% vs. 76%, p=0.043). Median overall survival (mOS) was significantly improved in patients who underwent CN (23.0 mo vs. 10.9 mo, p=0.039). Patients with NLR <5 also had superior mOS (16.7 mo vs. 6.2 mo; HR 0.53; 95% CI; 0.24-0.84; p=0.013). While CN was associated with substantially improved survival in patients with both NLR <5 (mOS 31.1 mo vs. 7.0 mo; HR 0.41; 95% CI, 0.18-0.64; p=0.0009) and NLR ≥5 (mOS 10.9 mo vs. 2.3 mo; HR 0.33; 95% CI, 0.11-0.69; p=0.009), the absolute survival difference was greater in patients with baseline NLR <5. Significant survival benefits associated with CN were maintained in multivariate analyses (HR 0.31; 95% CI, 0.18-0.55; p<0.0001). Conclusions: CN is associated with significantly improved OS in de novo mRCC. The incremental survival benefit associated with CN was seen irrespective of NLR.
