These include the small-molecule epidermal growth factor receptor inhibitors erlotinib (Tarceva®) and gefitinib (Iressa®), which are used to treat NSCLC patients, and monoclonal antibody therapies such as cetuximab (Erbitux®) and panitumumab (Vectibix®), which are primarily used in the treatment of metastatic colorectal cancers (mCRC)[5-7]. Here, EGFR is linked to non-small cell lung carcinoma.
