The Relationship Between a Urinary Cachectic Factor and Weight Loss in Advanced Cancer Patients

A 24K glycoprotein, the proteolysis-inducing factor (PIF), has been identified in mice and humans with cancer cachexia. Clinical cross-sectional studies found an association between the presence of PIF in urine and tumors of patients and weight loss. For the first time, we report results from a longitudinal study establishing the relationship between a urinary PIF pattern and persistent weight loss. Over time, cancer patients positive for the PIF pattern experienced weight loss, whereas those with a negative test gained weight.
