Urine and blood may hold key to kidney cancer treatment response
NCT ID NCT07436416
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study explored whether small particles called exosomes, found in blood and urine, can help predict how well treatment works in people with advanced kidney cancer. Researchers followed 91 patients for 16 weeks, collecting samples and comparing them to imaging results. The goal was to find patterns that could lead to a simple, non-invasive test to guide treatment decisions.
