Summary
Brief summary (as posted)
The study aims to explore the clinical utility of circulating tumour DNA (ctDNA) in assessing for alterations of anti-epidermal growth factor receptor (EGFR) primary resistance in RAS and BRAF wild-type metastatic colorectal cancer (CRC) patients treated with anti-EGFR monoclonal antibodies (cetuximab / panitumumab) in combination with fluorouracil (FU)-doublet chemotherapy.

Inclusion Criteria: * Patients with newly diagnosed stage IV colon or rectal cancer who are RAS/BRAF wild-type by routine tumor profiling and who are beginning standard-of-care treatment with fluorouracil-based doublet chemotherapy in combination with anti-EGFR monoclonal antibodies. Prior treatment with adjuvant therapy is allowed if completed more than 6 months prior to relapse of disease. Exclusion Criteria: * Pregnant women will be excluded from the study. * Patient unable to give informed consent will be excluded from the study. * Patients who have previously received chemotherapy in the metastatic setting. * Patients who have previously received adjuvant chemotherapy less than 6 months prior to relapse of metastatic disease.
