Öğe The relationship between pan-immune-inflammation value and survival outcomes in patients with metastatic renal cell carcinoma treated with nivolumab in the second line and beyond: A Turkish oncology group kidney cancer consortium (TKCC) study(Springer, 2022) Tural, Deniz; Yekedüz, Emre; Ertürk, İsmail; Karakaya, Serdar; Erol, Cihan; Ercelep, Özlem; Arslan, Çağatay; Sever, Özlem Nuray; Şentürk Öztaş, Nihan; Küçükarda, Ahmet; Can, Orçun; Öksüzoğlu, Berna; Şendur, Mehmet Ali; Karadurmuş, Nuri; Urun, Yüksel; Kılıçkap, SaadettinBackground Pan-immune-infammation value (PIV) is an easily accessible immune marker based on peripheral blood to estimate prognosis in patients with cancer. 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 (103 /mm3 ) x monocyte (103 /mm3 ) x platelet (103 /mm3 )/lymphocyte (103 /mm3 ). Results A total of 152 patients with mRCC were included in this study. According to cut-of 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.Öğe The relationship between systemic immune inflammation index and survival in patients with metastatic renal cell carcinomatreated withtyrosine kinase inhibitors(Nature Research, 2022) Yücel, Kadriye Bir; Yekedüz, Emre; Karakaya, Serdar; Tural, Deniz; Ertürk, İsmail; Erol, Cihan; Ercelep, Özlem; Öztaş Şentürk, Nihan; Arslan, Çağatay; Uçar, Gökhan; Küçükarda, Ahmet; Sever, Özlem Nuray; Kılıçkap, Saadettin; Can, Orçun; Yazgan, Satı Çoskun; Öksüzoğlu, Berna; Karadurmuş, Nuri; Şendur, Mehmet Ali; Ürün, YükselThis study aims to investigate the prognostic value of the systemic immune-inflammation index (SII)and its impact on survival in patients with metastatic renal cell carcinoma (mRCC). A total of 706patients with mRCC treated with tyrosine kinase inhibitors (TKIs)between January 2007 and June 2020 (i.e., sunitinib, pazopanib) were included in this study. SII was calculated in 621 patients with the following formula:[neutrophil (cellsx109/L) x platelet (cellsx109/L)] / lymphocyte (cellsx109/L).All patients were classified into SII-high and SII-low groups based on the cut-off value of SII at 756, which was the median SII level of our study group. The minimal follow-up duration was 10 months in all cohorts. The median age of patients was 60 (interquartile range (IQR):53–67) years. Three out of four patients were male. The majority of patients (85.7%) had clear cell histology, and sarcomatoid differentiation was observed in 16.9% of all patients. There were 311 and 310 patients in the SII-low and SII-high groups, respectively. In general, baseline characteristics were similar in each group. However, the rate of patients treated with sunitinib (63.3% vs. 49.0%, p < 0.001) and those who underwent nephrectomy (83.6% vs. 64.2%, p < 0.001) was higher in the SII-low group than in the SII-high group. On the other hand, patients with the IMDC poorrisk (31.6% vs. 8.0%, p < 0.001), those with bone (51.8% vs. 32.2%, p < 0.001) or central nervous system (12.9% vs. 5.8%, p = 0.026) metastasis, and those with Eastern Cooperative Oncology Group(ECOG) 2–4 performance score (28.1% vs.17.7%, p = 0.002) were more common in the SII-high group than in the SII-low group. The median overall survival (OS) was longer in the SII-low group than in the SII-high group (34.6 months vs. 14.5 months, p < 0.001). Similarly, the median progression-free survival (PFS) was longer in the SII-low group than in the SII-high group (18.0 months vs. 7.7 months, p < 0.001).In multivariableanalysis, SII was an independent prognostic factor for OS (hazard ratio (HR):1.39, 95% confidence interval (CI):1.05–1.85, p = 0.01) and PFS (HR:1.60, 95% CI:1.24–2.05, p < 0.001).Pre-treatment level of high SII might be considered a predictor of poor prognosisin patients with mRCC treated with TKIs.
