[The Correlation of Minimal Residual Disease with Prognosis in TCF3-PBX1+ Acute Lymphoblastic Leukemia in Children].

OBJECTIVE:To investigate the consistency between FCM and PCR on the detecting of MRD in TCF3-PBX1 +METHODS:55 cases of paediatric TCF3-PBX1 +RESULTS:Among the 55 children with TCF3-PBX1 ++--+--CONCLUSION:The detection result of MRD in TCF3-PBX1 detect by FCM and PCR shows better consistency. MRD positivity detected by FCM at the end of induction therapy (day 33) predicts a high risk of relapse in TCF3-PBX1 ALL patients.
