Understanding New Cachexia Subtypes Through Observational Epidemiological Research

The UNCOVER study is a longitudinal observational cohort focused on patients at high risk for cancer cachexia. At Kaiser Permanente Northern California, up to 800 individuals with advanced or unresectable non-small cell lung cancer, pancreatic adenocarcinoma, or colorectal cancer will be enrolled, as these malignancies carry a substantial risk of cancer cachexia, which is characterized by progressive loss of weight, muscle, and adipose tissue, accompanied by functional decline and reduced quality of life. Data collected includes demographic, physiologic, and clinical data, including tumor characteristics and biomarkers of inflammation, hormonal and metabolic status, body composition, physical function, and patient reported outcomes. Investigators will identify patient phenotypes (i.e., subgroups) that may reflect distinct biological or clinical pathways underlying cancer cachexia. By characterizing heterogeneity in cancer cachexia, this study aims to inform the development of improved diagnostic criteria and more targeted therapeutic strategies, ultimately enhancing clinical trial design and supportive care for patients with advanced colorectal, lung, or pancreatic cancer.
