Gastrointestinal Cancer

The focus of gastrointestinal pathology is the molecular diagnostics of inherited colorectal cancer and gastrointestinal tumors and, including KRAS, BRAF, NRAS and PIK3CA mutational testing in colorectal cancer for determination of therapeutic response to EGFR inhibitors. An algorithm for Lynch syndrome (hereditary non-polyposis colorectal cancer or HNPCC) testing is available, which includes the rationale for microsatellite instability testing (by PCR and/or IHC), BRAF mutational testing, and detection of MLH1 methylation. Germline analysis of MLH1, MSH2, MSH6, and PMS2 mutations are also offered as a part of the Lynch syndrome. Tests are also available for APC sequencing and MYH mutational tests. ARUP also offers the first blood-based screening test for colorectal cancer, based on the Septin 9 biomarker. ARUP’s test has a reported 90% sensitivity at 90% specificity for detecting colorectal cancer. ARUP is one of only two labs in the US to offer this test. HER2 testing is available for gastric cancers, and c-Kit mutation testing is offered for gastrointestinal stromal tumors. Circulating tumor cell counting (Cell Search™) is available for thereapeutic monitoring of colorectal cancer patients.
