This study evaluates the prognostic value of PIV in patients with metastatic renal cell carcinoma (mRCC) treated with nivolumab. Methods In this retrospective cohort study, patients with mRCC treated with nivolumab in the second line and beyond were selected from the Turkish Oncology Group Kidney Cancer Consortium (TKCC) database. PIV was calculated using the following formula: neutrophil -(10(3)/mm(3)) x monocyte -(10(3)/mm(3)) x platelet-(10(3)/mm(3))/lymphocyte -(103/mm(3)). Results A total of 152 patients with mRCC were included in this study. According to cut-off value for PIV, 77 (50.7%) and 75 (49.3%) patients fell into PIV-low (<= 372) and PIV-high (> 372) groups, respectively. In multivariate analysis, PIV-high (HR: 1.64, 95% CI 1.04-2.58, p = 0.033 for overall survival (OS); HR: 1.55, 95% CI 1.02-2.38, p = 0.042 for progression-free survival (PFS)) was independent risk factor for OS and PFS after adjusting for confounding variables, such as performance score, the International mRCC Database Consortium (IMDC) risk score, and liver metastasis. Conclusion This study established that pre-treatment PIV might be a prognostic biomarker in patients with mRCC treated with nivolumab in the second line and beyond.en10.1007/s00432-022-04055-5info:eu-repo/semantics/openAccessImmunotherapyRenal Cell CarcinomaBiomarkerTo-Lymphocyte RatioIndex SiiPrognostic-FactorsTherapiesMrccArticle1481235373546Q2WOS:0008004337000022-s2.0-8513070690635616728Q1
