Read our Kidney Cancer research guide →This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
Researchers want to understand how kidney cancer cells hijack the body's nutrients to fuel their growth. During your planned surgery or biopsy, some patients will receive a special nutrient infusion with a harmless, heavier form of carbon that researchers can track. By studying the tissue removed during your procedure, they can see exactly how cancer cells use these nutrients—knowledge that could lead to new treatments and better imaging techniques.
Doctors know that cancer cells use nutrients differently than normal cells, but they don't yet understand exactly which nutrients kidney cancers rely on in real patients. This study fills that gap so that future therapies can be designed to starve cancer cells or detect them more easily.
You likely qualify if…
You likely don't qualify if…
If you qualify, you will undergo your planned kidney cancer surgery or biopsy. Depending on which study group you're in, you may receive an infusion of a special nutrient during your procedure—this is completely safe and not radioactive. Researchers will collect and study the tumor tissue removed during your surgery or biopsy to understand how your cancer cells use different nutrients. There are no additional visits or ongoing treatments required beyond your standard surgical care.
