Non-colorectal GI tumors
Gastrointestinal stromal tumors (GIST)
This test is a single assay that uses formalin-fixed paraffin-embedded (FFPE) tissue to assess for common mutations in the KIT and PDGFRA genes, which are present in 85% to 90% of GIST tumors. The simplified results of this test can be useful for assessing prognosis and guiding treatment. Because of the prevalence of these mutations, this assay not only confirms the diagnosis of GIST but guides important decisions on therapy selection.
A Test in Focus
Rondell Graham, M.B.B.S., gives an overview of the gastrointestinal stromal tumor panel. He discusses when this testing should be ordered, how this testing improves upon previous testing approaches, and what clinical action can be taken due to the results of this testing.
