We hypothesize that a combination of C-Reactive Protein (CRP), Albumin, Neutrophil-Lymphocyte ratio (NLR), corrected calcium, and AST/ALT ratio into a RCC Inflammatory Score (RISK) could serve as a rigorous prognostic indicator. METHODS: Multicenter retrospective analysis of RCC patients undergoing nephrectomy for localized ccRCC. The optimal threshold for individual biomarkers was determined using grid search and receiver operating characteristic (ROC) analysis. Each patient was assigned to a RISK group based on sum of each marker score. Primary outcome was overall survival (OS) and secondary outcome was recurrence-free survival (RFS). Prognostic value of RISK was analyzed using the Kaplan-Meier (KM) method and multivariable Cox proportional regression models. Multivariable models adjusted for Age, sex, race, BMI, T and N-stage, tumor size, necrosis, grade, partial or radical surgery. RESULTS: 2,591 patients with localized ccRCC were identified with mean follow-up of 46 months. 812 (31%) patients were found to be in baseline risk group, while 1300 (50%) in low risk, 456 (18%) to intermediate, and 23 (0.9%) in high risk group. Higher RISK group were significantly associated with larger tumor size, necrosis, higher T- an N-stage, RCC grade. Multivariable models showed RISK to be an independent and significant predicter of both OS and RFS. In adjusted models for OS, compared to baseline risk, patients with Low [HR: 1.4, p=0.01], intermediate [HR:2.5, p=<.001], and High risk [HR: 5.4, p=<.001] had higher risk of death. In models for RFS, patients with intermediate [HR:1.6, p=0.02] had higher risk recurrence. CONCLUSIONS: RISK is an independent and significant predictor of overall survival in localized clear cell RCC while adjusting for established predictive histological factors. Notably, RISK is composed of standardized laboratory markers easily and cost-effectively obtained preoperatively and requires no surgical specimen, allowing crucial prognostic information to be integrated into medical decision making prior to surgery.
