The Role of Primary Tumour Location in the Selection of Biologics for the Treatment of Unresectable Metastatic Colorectal Cancer: An Endorsement of a Canadian Consensus Statement

This is a clinical practice guideline for adult patients with RAS wild-type unresectable metastatic colorectal cancer (mCRC) who are undergoing first-line or second-line chemotherapy. The guideline provides recommendations on the role of primary tumour location (PTL) in the selection of epidermal growth factor receptor (EGFR) monoclonal antibodies (mAbs) and vascular endothelial growth factor (VEGF) inhibitors, in addition to chemotherapy for the treatment of unresectable mCRC.
