The frequent occurrence of KRAS, PIK3CA, and BRAF was confirmed, and mutations not detected before in colon cancer were found in MET and ABL1. Twenty-five assays from the OncoCarta were replexed to form a new panel, termed ColoCarta, which will be used to screen an additional 800 tumors from NSABP clinical trial C0-7 with the purpose of identifying prognostic or predictive markers for stage II and III colon cancer. Here, ABL1 is linked to malignant colon neoplasm.
