PET scans may reveal which cancers trigger wasting syndrome
NCT ID NCT03568019
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study reviews medical records of 10,000 people with lung or gastrointestinal cancers to see if PET scans can identify tumors that cause cachexia—a condition of severe weight loss and weakness. Researchers will compare PET scan results with patients' weight and performance status. The goal is to better understand which tumors are linked to cachexia, not to test a new treatment.
