Özet
Background/Objectives: Nivolumab has been shown to be an effective treatment for metastatic renal cell carcinoma (mRCC); however, patient responses vary considerably. The objective of this study is to evaluate the prognostic value of the C-PLAN index in predicting survival outcomes for patients with mRCC treated with nivolumab. Methods: This retrospective cohort study included 81 mRCC patients previously treated with tyrosine kinase inhibitors who subsequently received nivolumab. The C-PLAN index, which includes C-reactive protein, performance status, lactate dehydrogenase, albumin, and derived neutrophil-to-lymphocyte ratio, was used to classify patients into “good” and “poor” prognostic groups. Results: The median overall survival (OS) was 22 months, and the median progression-free survival (PFS) was 6.7 months. Patients in the “poor” C-PLAN group exhibited significantly shorter OS and PFS than those in the “good” group (median OS: 13 vs. 31 months, p = 0.003; median PFS: 3 vs. 10 months, p = 0.007). The C-PLAN index was identified as an independent predictor of both OS (HR = 1.19, 95% CI: 1.11–3.43, p = 0.020) and PFS (HR = 1.71, 95% CI: 1.04–2.78, p = 0.032) in multivariate analysis. Conclusions: These findings suggest that the C-PLAN index may serve as a valuable prognostic tool, offering insights into survival outcomes for patients undergoing nivolumab therapy. Further prospective and multicenter studies are warranted to validate its clinical utility.
