 Imatinib mesylate is allowed to be applied to KIT-positive GISTs in Japan, but it should not be indiscriminately used for surgically treatable GISTs. Since the effect of Imatinib depends on the types of mutations of c-kit gene or PDGFR αgene, an analysis of the mutation of these genes is essential to predict the patient's response to the drug. Use of Imatinib as adjuvant therapy is now being studied, so the results will give information whether its use as adjuvant therapy is required or not. In patients with regrowth of GISTs after Imatinib administration, the drug could be continuously applied if the resistant clone has been successfully removed.
