Evaluation of a Non–race-based Equation in Predicting Glomerular Filtration Rates Postnephrectomy in a Racially Diverse Cohort

Editorial Comment

“…Nicaise, Schmeusser, and colleagues provide an insightful follow-up study 1 of an analysis published by our group. 2 The authors examined the application of non–race-based glomerular filtration rate (GFR) formulas in predicting postoperative renal function following radical and partial nephrectomy for localized renal malignancy.…”

“…We demonstrated how this transition reveals an accelerated decline in GFR among Black patients following nephrectomy, which supports the consideration of early nephrology referral to maximize renal function and prevent chronic kidney disease upstaging. 2 Although not discussed, it is important to mention the potential oncologic implications of nonerace-based GFR equations in Black patients during this surveillance period. Given the risk of recurrence or secondary malignancy, which may require additional medical or surgical treatment, GFR is an important factor in determining eligibility for certain therapies and clinical trials.…”
