Popis: Detection of minimal residual disease (MRD) by analysis of the PML-RAR alpha fusion transcript using the RT-PCR method is routinely carried out on peripheral blood and bone marrow of patients with APL (AML, FAB:M3). Therapy aims to achieve repeated negative results in these patients thus confirming clinical complete remission. We report a case of APL in second complete remission in which no leukemic cells had been detected in BM and PB for 20 months, and in which PBPC-pheresis was carried out for future transplantation. In two of five pheresis PML-RAR alpha fusion transcripts were detected. This shows that the residual leukemic population may only reach detection level after enrichment by PBPC-pheresis.
