Below Safety Limits, Every Unit of Glomerular Filtration Rate Counts: Assessing the Relationship Between Renal Function and Cancer-specific Mortality in Renal Cell Carcinoma

The hypothesis that renal function could influence oncological outcomes is supported by anecdotal literature. To determine whether estimated glomerular filtration rate (eGFR) is related to cancer-specific mortality (CSM) in patients who had undergone surgery for renal cell carcinoma (RCC). A retrospective analysis of 3457 patients who underwent radical (39%) or partial nephrectomy (61%) for cT1–2 RCC between 1990 and 2015. The eGFR was...
