New study tracks muscle loss in cancer patients to uncover hidden clues

This study follows 200 people with cancers of the esophagus, stomach, pancreas, colon, or rectum who are scheduled for surgery, along with some healthy controls. Researchers will track weight, muscle mass, physical activity, quality of life, and immune markers over a year to better understand cachexia—a condition causing muscle wasting and fatigue. The goal is to get a complete picture of how cachexia develops and changes over time, which could help improve care.
