Genetic Testing in Screening Patients With Metastatic or Unresectable Colon or Rectal Cancer for a COLOMATE Trial

This trial screens patients with colon or rectal cancer that has spread to other places in the body (metastatic) or cannot be removed by surgery (unresectable) for genetic mutations for recommendation to a molecularly assigned therapy. Identifying gene mutations may help patients enroll onto target companion trials that target these mutations.
