Methods: Reverse transcription Polymerase chain reaction (RT/PCR) was used to detect MRD of patients with APL. Results: MRD positive rate in patients with APL was 92.8% (39/42) before treatment and 56.7 (21/37) immediately after the ATRA or chemotherapy-induced CR. Furthermore, MRD positive rate was related to the relapse in APL patients and could be considered as a marker to predict the relapse of patients with APL after CR. The MRD detection could also be applied to direct the consolidation therapy to prevent relapses. Conclusion: RT-PCR is valuable to monitor MRD and can be used as a marker to predict relapses.展开更多
