Popis: 12064 Background: We previously showed that estimated glomerular filtration rate (eGFR) based on serum creatinine (Scr)(eGFRcr) using the 2009 CKD-EPI equation performed better than Cockroft-Gault equation (CG) in solid tumor patients in Brazil (Onco-GFR Study). In that study, eGFR based on Scr and cystatin C (Scys)(eGFRcr-cys) using the 2012 CKD-EPI was the most accurate equation and suitable for use as a confirmatory test. The CKD-EPI 2009 eGFRcr and 2012 eGFRcr-cys equations include a term for race (Black vs. non-Black). The 2021 CKD-EPI eGFRcr and eGFRcr-cys equations do not include race and are now recommended in the US, but have not been assessed in a multi-racial population or in cancer patients. The aim of this study is to evaluate the performance of the 2021 CKD-EPI equations in the Onco-GFR Study. Methods: Measured GFR (mGFR) was determined using the plasma clearance of 51Cr-EDTA. Scr and Scys assays were traceable to international standards. Results: A group of 1,200 patients recruited between April 2015 and September 2017 were included for analysis. Patients were 58.8±13.2 years, 50.8% male. Race distribution was Black participants 12.8% and non-Black participants 81.2%. Mean (SD) mGFR was 78.5±21.7 ml/min/1.73 m2. For eGFRcr, the overestimation of mGFR was larger for the 2021 vs. 2009 equation -10.0 vs. 8.1 ml/min/1.73m2, resulting in lesser accuracy 1-P30 of 22.3 vs. 19.1, but still more accurate than CG equation (1-P30 of 24.9, P = 0.05). For eGFRcr-cys, the overestimation of mGFR was larger for the 2021 vs. 2012 equation (-4.1 vs. -2.0 ml/min/1.73m2). eGFRcr-cys using the 2021 equation was more accurate than eGFRcr using the 2021 equation and eGFRcys using the 2012 equation (1-P30 9.8 vs. 22.3 and 12.3, p-values < 0.001 and 0.01, respectively) (Table). Conclusions: 2021 CKD-EPI eGFRcr equation race performed better than CG. 2021 CKD-EPI eGFRcr-cys performed better than 2021 eGFRcr and 2012 eGFRcys equations. Removing race from eGFR equations represents an advance and should be incorporated in cancer care. [Table: see text]
