An observational study to investigate cachexia in participants with non-haematological cancer.

A single-centre, non-randomised, observational study. This study will investigate the systemic metabolic and immunological changes that occur in cachexia. The aim is to better understand the mechanism(s) underlying weight loss in people with non-haematological cancer. This will help to facilitate future research to generate treatments to reverse weight loss and improve outcomes.
