Expression of Epiregulin and Amphiregulin and <i>K-ras</i> Mutation Status Predict Disease Control in Metastatic Colorectal Cancer Patients Treated With Cetuximab

Abstract

Patients with tumors that have high gene expression levels of epiregulin and amphiregulin and patients with wild-type K-ras are more likely to have disease control on cetuximab treatment. The identified markers could be developed further to select patients for cetuximab therapy.
