Image Guided Treatment Optimization With Cetuximab for Patients With Metastatic Colorectal Cancer

Summary

In this study the investigators will evaluate the uptake of 89Zirconium labeled cetuximab in extra-hepatic colorectal metastases. The investigators hypothesize that uptake of 89Zr-cetuximab is required for response to cetuximab. If no uptake is present the investigators will escalate the dose cetuximab and repeat the 89Zr-cetuximab PET. The investigators will evaluate the clinical benefit rate of cetuximab in the patients with and without uptake. The ultimate goal is to create a selection tool that can predict response of cetuximab.
