Definitions of PFS-EFS in CML Kantarjian et al. Blood 2010:116; Abst #672.
Outcome According to Different Definitions of EFS/PFS - Because EFS and PFS are important in determining whether new TKIs are better than imatinib in front-line therapy, precise and common definitions of these endpoints are needed. Kantarjian et al. Blood 2010:116;Abst #672.
