Lineage switch in acute leukemia

Lineage 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 ...

Molecular 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...

Lineage switch from acute lymphoblastic leukemia to myeloid leukemia

Lineage Switch in Childhood Leukemia: A Case Report and Review of Literature

Acute leukemia which is the most common cancer in children is a heterogeneous group of clonal malignancies. The conversion of the leukemic cell lineage during the course of the disease or later is termed lineage switch. It has been rarely reported in the literature. In leukemia lineage switch, conversions from lymphoblastic leukemia to myeloid leukemia or vice versa are reported. Herein, we rep...

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...
