Abstract

We report a 10-year-old male with relapsing Ph-like acute lymphoblastic leukemia (ALL) bearing ATF7IP/PDGFRB translocation. He was refractory to conventional therapy, and was finally treated with single-agent second-generation TKI dasatinib. The therapeutic response was prompt, with the disappearance of minimum residual disease (MRD) based on genomic PCR analysis within 3 months, and he has maintained complete molecular remission for 12 months. This case report describes an early-phase response to TKI monotherapy on Ph-like ALL, and technical tips for MRD monitoring on long-term follow-up.
