ABSTRACT

O STI (imatinib, Glivec) é um inibidor da tirosina quinase BCR-ABL, responsável pela patogênese da leucemia mielóide crônica (LMC). Um total de 110 pacientes com LMC na fase crônica (FC) que falharam ou foram intolerantes ao tratamento com interferon, fase acelerada (FA) e crise blástica (CB) foram tratados com imatinibe entre dezembro de 2000 e setembro de 2003. Resposta hematológica completa e resposta citogenética maior foram observadas em 95,9 por cento e 69,4 por cento respectivamente em pacientes em FC e 93,2 por cento e 36,4 por cento em FA. Apenas 2 pacientes na CB estão vivos. O imatinib foi bem tolerado com altas taxas de resposta. /STI571 (Imatinib, Glevec) is an inhibitor of the Bcr-Abl tyrosine kinase that is central to the pathogenesis of chronic myelogenous leukemia (CML). A total of 110 patients with CML chronic phase (CP) who failed or were intolerant to interferon, accelerated phase (AP) and blastic crisis (BC) were treated with imatinib from December 2000 until September 2003. Complete hematologic response and major cytogenetic response were observed in 95,9 per cent and 69,4 per cent respectively of patients in CP and 93,2 per cent and 36,4 per cent in AP. Only 2 patients are alive in BC. Imatinib is well tolerated with high rates of response...
