Minimal  Residual  Disease  Monitoring  In  t(8;21)  Acute  Myeloid  Leukemia     Based  On  RUNX1-­‐RUNX1T1  Fusion  QuanBficaBon  On  Genomic  DNA   Nicolas  Duployez,  Aline  Renneville,  Olivier  Nibourel,  Alice  Marceau-­‐Renaut,  Nathalie  Helevaut,  Aurélie  Caillault,     Celine  Villenet,  Karine  Celli-­‐Lebras,  Nicolas  Boissel,  Eric  Jourdan,  Herve  Dombret,  MarFn  Figeac  and  Claude  Preudhomme  

Background   Although   acute   myeloid   leukemia   (AML)   with   t(8;21)   belongs   to   the   favorable   risk   AML   subset,   relapse   incidence   may   reach   30-­‐40%  in  those  paFents.   Minimal   residual   disease   monitoring   (MRD)   based   on   the   quanFficaFon   of   RUNX1-­‐ RUNX1T1   fusion   transcript   by   real-­‐Fme   quanFtaFve   PCR   (RQ-­‐PCR)   has   been   o  bbe   e  an   independent   prognosFc   factor  for  the  risk  of  relapse.     reported  tto   an   independent   prognosFc   factor  for  the  risk  of  relapse.     In  this  study,  we  invesFgated  the  feasibility  and  performances  of  RUNX1-­‐   RUNX1T1  DNA  as  MRD  marker  in  AML  with  t(8;21).
