Performance of Creatinine and Cystatin-Based Equations on Estimating Measured Glomerular Filtration Rate in People with Hematological and Solid Cancers.

Background: Glomerular filtration rate (GFR) assessment is important in clinical practice, with implications for diagnosis, prognostication, and drug dosing. People with cancer are at risk of imprecision in GFR estimation. This cross-sectional study evaluated the performance of various creatinine and cystatin C-based equations in comparison to measured GFR (mGFR) in people with cancer.
