- Description
- A 16-year-old boy with B-cell acute lymphoblastic leukemia refractory to conventional chemotherapy and harboring an IKZF1 deletion (delta 2-7) and a 5q33 microdeletion resulting in an EBF1-PDGFRB fusion responded to continuous imatinib (400 mg/d) during consolidation. Following consolidation therapy that included dexamethasone, vincristine, etoposide, cytarabine, and high-dose methotrexate, MRD declined to 10^-5 and the patient underwent bone marrow transplant. MRD performed at 105 days post-BMT found no detectable blasts with a sensitivity of 10^-5.
