An Investigation of Kidney and Urothelial Tumor Metabolism in Patients Undergoing Surgical Resection and/or Biopsy (NCT04623502)
🩺 Plain-English Summary (8th-Grade Level)
The purpose of this study is to understand the metabolism of cancers involving the kidney, including renal cell carcinomas and urothelial cell carcinomas, and how kidney cancers use different types of fuel to support tumor growth. This study uses specially labeled nutrient tracers of compounds normally found circulating in the blood. The nutrients (glucose, fructose, glutamine, acetate, and lactate) are also found in common foods. A nutrient tracer will be given to the participants through an intravenous (IV) catheter during surgery or biopsy, and blood will be collected every 30 minutes during the infusion to monitor safety parameters and the nutrient tracers. The investigators will collect a tissue sample after the completion of surgery. Participants not having an infusion will have their tissue collected after surgery or biopsy. Participation in this study will not change patient care. All patients will receive standard of care treatment as determined by their doctors.
Who can join: To join this study, participants generally need to meet the listed inclusion criteria (5 items) and avoid the listed exclusions (4 items).
