Scientists track Cancer's diet in real time during surgery
NCT ID NCT04623502
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study looks at how kidney and bladder cancers use nutrients like sugar and fat to grow. Participants receive a harmless nutrient tracer during surgery or biopsy, and researchers collect blood and tissue samples to analyze cancer metabolism. The study does not change standard treatment and aims to better understand these cancers.
