Best response of target lesions by patient, regardless of k-ras status (evaluable patients). CR – complete response, PR – partial response, SD – stable disease, m - k-ras mutant, * - k-ras wildtype Two patients (one patient with k-ras wt and one patient with k-ras mutant tumour) were not evaluable for response as they were excluded from the study after cycle one without response evaluation. One patient with stable disease had no change in tumor size.
