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.
