This study was purposed to comparatively analyse the value of PCR and FCM for dynamic monitoring minimal residual disease (MRD) of acute promyelocytic leukemia. The patients with acute promyelocytic leukemia hospitalized in our hospital from January 2011 to December 2012 were observed and all achieved complete remission after remission induction therapy. Before the chemotherapy, the bone marrow cell morphology examination, polymerase-chain reaction (PCR) and multi-parameter flow cytometry (FCM) were performed for each patient. Then the detection results were statistically analyzed. The 477 specimens were achieved from 159 detections for 48 patients. The results showed that 3 specimens were found to be relapsed by bone marrow cell examination, and other specimens were complete remission;PCR detection confirmed 7 positive, and the FCM confirmed 19 positive. There wasn't significant difference between PCR and FCM by kappa test (P > 0.05). It is concluded that FCM is as sensitive as PCR in evaluating the treatment effect of acute promyelocytic leukemia.
