Description
Tumor sequencing in pre- and post-therapy specimens from ten individuals with mCRC who experienced disease progression after a prior response to cetuximab with chemotherapy was performed. The S492R mutation was identified in two persons. One of them had already died, the other received treatment with panitumumab and had a partial response (50% tumor reduction in all liver lesions) for 5 months.
