Abstract

We describe a patient with acute myelogenous leukemia (AML) with t(16;21)(p11;q22) translocation, whose minimal residual disease (MRD) both in cerebrospinal fluid (CSF) and bone marrow (BM) was monitored by reverse transcriptase-polymerase chain reaction (RT-PCR). A TLS/ERG-FUS fusion transcript, which is known to be expressed by t(16;21)(p11;q22) translocation, was detectable by RT-PCR both in BM and CSF cells in the first complete remission, suggesting the existence of MRD. The disease relapsed 6 months after its onset and allogeneic peripheral blood stem cell transplantation (PBSCT) was undergone. A TLS/ERG-FUS fusion transcript became rapidly below the detection level after PBSCT. These findings suggest the usefulness of RT-PCR for the detection of MRD in CSF, which contains a limited number of cells, as well as BM.

Acute Myeloid Leukemia

Acute myeloid leukemia (AML) is a clinically and genetically heterogeneous disease with approximately 20,000 cases per year in the United States. AML also accounts for 15-20% of all childhood acute leukemias, while it is responsible for more than half of the leukemic deaths in these patients. Here is the latest research on this disease.

Blood And Marrow Transplantation

The use of hematopoietic stem cell transplantation or blood and marrow transplantation (bmt) is on the increase worldwide. BMT is used to replace damaged or destroyed bone marrow with healthy bone marrow stem cells. Here is the latest research on bone and marrow transplantation.
