Peripheral blood flow cytometry for the diagnosis of pediatric acute leukemia: Highly reliable with rare exceptions
Abstract
Recent data have demonstrated the high sensitivity and specificity of peripheral blood flow cytometry (PBFC) for the diagnosis of pediatric leukemia; however, diagnostically significant immunophenotypic discrepancies between PBFC and bone marrow (BM) evaluation, which result in different lineage assignment and treatment protocols, can rarely occur. Here, we sought to further characterize the performance of PBFC for pediatric leukemia and highlight the exceptions when PBFC can result in misdiagnosis.
