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

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.
