Observational Study to Identify Subtypes of Cancer Cachexia in Adults with Advanced or Unresectable Colorectal, Lung, or Pancreatic Cancer

What this Trial Is About

This research aims to better understand cancer cachexia CC, a condition involving weight, muscle, and fat loss that affects patients with advanced colorectal, lung, or pancreatic cancer that cannot be removed by surgery or is at stage IV. CC is linked to reduced physical function, lower quality of life, and poorer survival. The study seeks to identify different subtypes of CC based on patient characteristics to improve diagnosis and tailor treatments more effectively than a one-size-fits-all approach. It also aims to validate these subtypes and explore tumor factors that may contribute to CC. Participants will complete surveys and physical function tests lasting about 30 minutes each, provide blood samples and archived tumor tissue, and wear an actigraph device for 7 days to monitor sleep and activity. These assessments occur at the start of the study and again after three months. Standard imaging scans such as CT or PETCT are performed as part of usual care throughout the study. Medical records are reviewed at baseline, 3 months, and 1 year to collect comprehensive clinical data. During the study, researchers will evaluate physical function, symptoms, body composition, blood biomarkers, and activity levels to identify distinct CC diagnostic subtypes and their association with survival. Surveys and functional tests help measure symptoms and physical ability. The actigraph tracks daily activity and sleep patterns. The study follows participants for up to one year to monitor changes and outcomes, aiming to build a detailed database to support future research and clinical trials for cancer-related weight and muscle loss.
