Description
Summary:Acute lymphoblastic leukemia represents a heterogeneous group of hematological malignancies, defined by clonal proliferation of lymphoid cells. Immunophenotyping by flow cytometry and molecular analysis for the detection of genetic anomalies are clinical standard procedures for diagnosis, sub-classification and post-therapeutic evaluation. Samples from 105 patients diagnosed with acute lymphoblastic leukemia were immunophenotyped at diagnosis and were investigated by molecular analysis in order to identify the occurrence of four fusion genes: MLL-AF4, TEL-AML-1, BCR-ABL-p190, E2A-PBX-1. There were no associations found between the immunophenotype and the presence of any fusion genes evaluated. Both methods in combination remain a prerequisite for an improved subclassification of hematological malignancies, therapeutic decision, and evaluation of treatment response.
