What testing do I need to have in order to get gleevec (imatinib)?

C-kit analysis. Whether patients with gist are candidates for Gleevec (imatinib) depends on the status of a particular gene called c-kit, or cd117. This is a test that must be run on the tumor biopsy tissue and is generally coordinated with the help of the pathology laboratory. In select cases, some patients are candidates for Gleevec (imatinib) regardless of their c-kit results, but this is highly individualized.
