ABSTRACT
The discovery of the Philadelphia chromosome in 1960, and of the BCR-ABL oncogene in 1984, enabled the development in subsequent years of a targeted therapy that revolutionized the treatment of chronic myeloid leukemia, thus changing its natural history. The use of imatinib resulted in a significant improvement of the prognosis and outcome of patients with chronic myeloid leukemia. However, the occurrence of mechanisms of resistance or intolerance precludes the eradication of the disease in some of the patients. Second-generation tyrosinekinase inhibitors are efficient in most of these patients, except for those with T315I mutation. We present an overall review of chronic myeloid leukemia, with emphasis on the progress in its treatment.
RESUMO
As descobertas do cromossomo Filadélfia, em 1960, e do oncogene BCR-ABL, em 1984, permitiram o desenvolvimento, nos anos subsequentes, de uma terapia-alvo que revolucionou o tratamento da leucemia mieloide crônica, mudando sua história natural. O uso do imatinibe resultou numa melhora expressiva do prognóstico e da evolução dos pacientes com leucemia mieloide crônica. Entretanto, surgiram mecanismos de resistência ou intolerância, que impedem a erradicação da doença numa parcela dos pacientes. Os inibidores de tirosina quinase de segunda geração mostram eficácia namaioria desses pacientes , exceto naqueles com mutação T315I. Aqui, foi realizada uma revisão global da leucemia mieloide crônica, destacando-se a evolução de seu tratamento.
