Association between serum ligands and the skin toxicity of anti-epidermal growth factor receptor antibody in metastatic colorectal cancer.

ABSTRACT: Skin toxicity is a known clinical signature used to predict the prognosis of anti-epidermal growth factor receptor (EGFR) antibody treatment in metastatic colorectal cancer (mCRC). There are no biological markers to predict skin toxicity before anti-EGFR antibody treatment in mCRC patients. Between August 2008 and August 2011, pretreatment serum samples were obtained from KRAS wild-type (WT) patients who received anti-EGFR antibody treatment. Serum levels of ligands were measured by ELISA. A total of 103 KRAS WT patients were enrolled in the study. Progression-free survival and overall survival of patients with a high grade (grade 2-3) of skin toxicity were significantly longer than those with a low grade (grade 0-1) of skin toxicity (median progression-free survival, 6.4 months vs 2.4 mon
