Significance of Cross Lineage Antigen Expression in Acute Lymphoblastic Leukemia
Background: Aberrant expression of cross-lineage antigens gives valuable insight into the diagnosis and prognosis of acute leukemia. In countries like India, cytogenetic tests are widely accessible. Exploring the prognostic value of an accessible test is of great importance. Therefore, establishing a population-specific immunophenotype database will enable to design an antibody panel equipped t...
متن کاملLineage infidelity in acute leukemia.
Blast cells from 20 patients with acute leukemia (13 diagnosed myeloblastic and 7 as lymphoblastic, using the FAB classification) were studied using antibodies to lineage-specific differentiation markers. The phenotypic findings were usually consistent with the clinical diagnosis. However, examples were encountered where individual blast cells had a cytoplasmic marker of one lineage and a surfa...
متن کاملLineage switch in acute leukemia.
Conversions of leukemic cell lineage (lymphoid or myeloid) have been reported only rarely. Our review of the cytochemical and immunophenotypic features of 89 cases of childhood leukemia in marrow relapse indicated lineage switch (lymphoid to myeloid or the reverse) in six patients (6.7%). Five patients with acute lymphoblastic leukemia (ALL) at diagnosis had converted to acute nonlymphoblastic ...
متن کاملTranscriptional and Microenvironmental Regulation of Lineage Ambiguity in Leukemia
Leukemia is characterized by the uncontrolled production of leukemic cells and impaired normal hematopoiesis. Although the combination of chemotherapies and hematopoietic stem cell transplantation has significantly improved the outcome of leukemia patients, a proportion of patients still suffer from relapse after treatment. Upon relapse, a phenomenon termed "lineage switch" is observed in a sub...
متن کاملMolecular heterogeneity in acute leukemia lineage switch.
Six cases of acute leukemia that underwent lineage switch from acute lymphocytic leukemia to acute myelogenous leukemia are reported. The mean age of the patients was 24 years, time to conversion was 36 months, and survival after conversion was only 3 months. Of the three cases which showed abnormal metaphases at both diagnosis and conversion, two (cases 2, 5) showed related cytogenetic abnorma...
