title: Subdural hematoma during therapy of gastro-intestinal stromal tumor (GIST) with Imatinib mesylate.
abstract: Imatinib mesylate is a widely used tyrosine-kinase inhibitor (TKI) in chronic myeloid leukemia (CML) treatment. Imatinib has contributed to complete and prolong cytogenetic responses so that it is now the standard treatment of CML. Recently, Imatinib mesylate has shown a significantly prolonged progression-free survival and overall survival in metastatic and locally advanced c-Kit positive gastro-intestinal stromal tumors (GISTs) and more recently a prolonged disease-free survival in operated high risk GIST. Imatinib is a welltolerated treatment with few side effects mainly gastro-intestinal symptoms (nausea, vomiting and diarrhea), headaches, rash and periorbital edema. Hemorrhage incidents are rare in patients treated with Imatinib. They are more frequently seen in CML patients. Hemorrhage incidents in CML include in many cases upper gastro-intestinal (GI) tract bleeding and central nervous system bleeding in rare ones. In GIST patients treated with Imatinib, hemorrhage incidents are exclusively made of upper GI tract bleeding consecutive to tumor perforation or necrosis. In our observation, we present the case of a subdural hematoma occurring in a patient treated with adjuvant Imatinib for a high risk localized gastric GIST. No other case of subdural hematoma in GIST treated with Imatinib has been reported in literature.
