Abstract

Acute promyelocytic leukemia (APL) is a subtype of acute myelogenous leukemia (AML) that is characterized by the presence of a PML/RAR alpha fusion gene resulting from t(15;17). Peripheral stem cell transplantation (PSCT) has been used to treat patients with AML. To assess the presence of minimal residual disease (MRD) and the contamination of leukemic cells in peripheral stem cells (PSCs), we examined six patients with APL who were undergoing PSCT, using reverse transcriptase polymerase chain reaction analysis to detect the mRNA of the PML/RAR alpha fusion gene. The fusion gene was expressed in the bone marrow cells during the early phase of a complete remission and in some of the PSCs. Detection of the fusion gene can be useful in monitoring for leukemic cell contamination of PSCs and for predicting a relapse of APL.

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.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.
