概要	BACKGROUND:The role of systemic inflammatory markers, including C-reactive protein (CRP), the neutrophil/lymphocyte ratio (NLR), and the platelet/lymphocyte ratio (PLR), in predicting survival for patients with metastatic renal cell carcinoma receiving second-line molecular-targeted therapy (mTT) after first-line tyrosine kinase inhibitor failure remains unclear. Thus, we investigated the relationship between systemic inflammation and survival in such patients.PATIENTS AND METHODS:Sixty-three patients were evaluated. Progression-free survival (PFS) and overall survival (OS) after second-line mTT initiation were evaluated according to the inflammatory marker levels. In addition, the prognostic factors for survival were examined.RESULTS:The receiver operating characteristic curves for CRP, NLR, and PLR had areas under the curve of 0.779, 0.619, and 0.655, respectively; no significant differences were noted. The corresponding cutoff values were 0.48, 2.53, and 183. Patients with higher CRP (n = 40), NLR (n = 32), and PLR (n = 22) levels had significantly lower PFS and OS than those with lower CRP, NLR, and PLR levels. Multivariate analyses showed that CRP was the sole independent predictor for PFS and OS.CONCLUSION:Systemic inflammation is associated with survival after second-line mTT. In particular, CRP was a strong independent predictive biomarker of prognosis.
