The Prognostic Value of Systemic Inflammatory Markers in Advanced Renal Cell Carcinoma Patients Treated With Molecular Targeted Therapies

BACKGROUND/AIM: The present study examined the impact of systemic inflammatory markers including C-reactive protein (CRP)/Albumin (Alb) and neutrophil lymphocyte ratio (NLR)/Alb on the prognosis of patients treated with first line molecular targeted therapy for advanced RCC. PATIENTS AND METHODS: A total of 131 patients with advanced RCC treated with molecular targeted therapy as first line treatment from May 2008 to April 2019 were retrospectively analyzed. RESULTS: High CRP, high NLR, low Alb and high CRP/Alb showed significantly worse progression-free survival (PFS) and overall survival (OS) than low CRP, low NLR, high Alb, low CRP/Alb and low NLR/Alb, respectively. In multivariate analyses, prior nephrectomy (p=0.0321) and NLR/Alb ratio (p=0.0327) were independent prognostic factors for PFS. Furthermore, prior nephrectomy (p=0.0013) and CRP/Alb ratio (p=0.0020) were independent prognostic factors for OS. CONCLUSION: CRP/Alb and NLR/Alb ratios are useful and independent prognostic biomarkers in patients with advanced RCC treated with molecular targeted therapy.
