OBJECTIVE: The occurrence of cryptic Philadelphia (Ph) chromosome translocation is rare in BCR-ABL1-positive acute lymphoblastic leukemia (BCR-ABL1+ ALL) and is of unknown significance in the tyrosine kinase inhibitor (TKI) era. METHODS: We retrospectively studied a series of adult patients receiving TK...
ABSTRACT Introduction and objective: In this study, we evaluated the influence of the transcript type on hematological and clinical parameters, as well as the event-free survival of 50 patients in the Chronic myeloid leukemia chronic phase. Methods: We reviewed the medical records of 55 patients with C...
Abstract Background Imatinib mesylate has revolutionized the treatment of chronic myeloid leukemia leading to significant reductions of BCR-ABL1 transcript levels in peripheral blood. Objective To evaluate the response to imatinib mesylate treatment (400 mg/day) in Brazilian patients in the chronic pha...
Actualmente las guías clínicas para el manejo de pacientes con leucemia mieloide crónica incluyen el monitoreo molecular de BCR-ABL1 por PCR cuantitativa en tiempo real; esta metodología permite definir la respuesta molecular. A pesar de la probada importancia pronóstica de la respuesta molecular, e...
CONTEXT: Identification of Philadelphia chromosome or BCR/ABL gene rearrangement in chronic myeloid leukemia is important at diagnosis as well as after treatment. OBJECTIVE: To compare the results of karyotyping using fluorescent in-situ hybridization (FISH) upon diagnosis and 1 year after bone marrow tr...
The focus of the study of minimal residual disease (MRD) is to redefine the concept of remission by using more sensitive molecular techniques to detect level of disease burden below that of conventional pathology. The detection of the chimeric bcr-abl mRNA transcript in chronic myeloid leukemia (CML) is ...
