RESUMO

The molecular analysis of chromosomal abnormalities associated with hematological malignancies allowed the identification of genes involved in theses rearrangements as well as of some recurrent mechanisms. Polymerase chain reaction [PCR] tools are now available to detect these rearrangements, allowing a better follow-up of these diseases. Chronic myeloid leukemia is a myeloproliferative disorder characterized by a reciprocal translocation t[9;22][q34;q11] which results in a bcr-abl fusion gene. Retro-transcription polymerase chain reaction [RT-PCR] is used to detect bcr-abl to establish diagnosis and to monitor patients. We report here the results of 30 patients samples tested in the hematology laboratory at Pasteur Institute, diagnosed as chronic myeloid leukemia and monitored with RT-PCR. Our results highlight the interest of molecular tools to diagnose and monitor patients mainly when cytogenetic techniques are irrelevant such as cases with complex chromosomal rearrangements or when patients achieve Philadelphia negativity after treatment
