It may also help doctors select the best treatment for patients and predict their response to treatment. PURPOSE: This randomized phase II/III trial is studying how well tumor tissue testing works in selecting treatment for patients with metastatic or locally advanced colorectal cancer.2009-07-152077926NCT009758972008-008323-15ISRCTN83171665
