Detection of minimal residual disease with acute promyelocytic leukemia in complete remission by flow cytometry and the reverse transcription polymerase chain reaction
ObjectiveTo appraise the consistency and its clinical significance by using two methods of immunity and biology to detect minimal residual disease(MRD) of the same periods patients with acute promyelocytic leukemia(APL) in complete remission(CR). MethodsThe PML-RARα fusion gene of APL-CR patients was detected by using the reverse technology of polymerase chain reaction(RT-PCR). CD13/CD45 and CD33/CD45 were detected by using FCM. Results28 cases with APL-CR 1-5 year who were diagnosed definitely, were respec...
