Özet
Aims: To investigate the effect of uric acid level on prognosis in patients with metastatic renal cell carcinoma (mRCC) treated with nivolumab. Materials and methods: This retrospective study utilized data from the Turkish Oncology Group Kidney Cancer Consortium (TKCC), which is a multicenter registry encompassing 13 cancer centers across Türkiye. Results and conclusions: A total of 189 patients were included in the study. The median age was 61 years in all cohort. Univariable analyses revealed longer TTF (17.87 vs. 6.57 months, p = 0.014) and OS (52.01 vs. 25.36, p = 0.032) in the uric acid-high (UAH) group than in the uric acid-low (UAL) group. In multivariable analyses, low uric acid level emerged as an independent risk factor for OS (hazard ratio (HR): 1.82, 95% confidence interval (CI): 1.09–3.05; p = 0.022), whereas no significant association was observed with TTF (HR: 1.24, 95% CI: 0.72–2.13; p = 0.431). While uric acid levels were a significant independent prognostic factor for OS, no association was found with TTF. Our findings underscore the prognostic importance of uric acid in mRCC, suggesting its potential role as a biomarker for risk stratification.
