title: [Imatinib--a breakthrough in the treatment of gastrointestinal stromal tumors (GIST)].
abstract: Gastrointestinal stromal tumours (GISTs) are rare gastro-intestinal, mesenchymal tumours characterized by the expression of a receptor with tyrosine kinase activity called c-kit. A new drug, Imatinib, is a potent inhibitor of a subgroup of the tyrosine kinase family comprising BCR-ABL, platelet-derived growth factor, and c-kit. Imatinib represents the first systemic treatment with a clinical effect on patients with metastatic or unresectable GISTs, which are known to be resistant to chemo and radiotherapy. In the first phase I and II studies confirmed partial responses were seen in 53% and 59% of the patients respectively.
