Most kras mutants make it so the patient cannot benefit from the chemotherapy drug, cetuximab; We previously showed that kras mutations were associated with resistance to cetuximab in 30 crc patients. The introduction of new cytotoxic agents and new targeted therapies has significantly broadened the therapeutic options for and the outcomes of patients with metastatic colorectal cancer (crc). These results were published in the british journal of cancer. Outcome was reassessed in subgroups defined by extended ras mutation testing. Eleven of the 30 patients (37%) responded to cetuximab.
