A case of 8p11 myeloproliferative syndrome with BCR-FGFR1 gene fusion presenting with trilineage acute leukemia/lymphoma, successfully treated by cord blood transplantation.
This study further supports the evidence that MLL breakpoints in therapy-related acute leukemia with MLL-AFF1 are clustered in the telomeric half of the breakpoint cluster region that contains topo II recognition sites.
The introduction of the tyrosine kinase inhibitors (TKI) into the treatment of patients with Ph or BCR-ABL1-positive acute lymphoblastic leukemia has revolutionized the treatment of this poor prognosis acute leukemia.
The breakpoint cluster region of the MLL gene (MLLbcr) is frequently rearranged in therapy-related and infant acute leukaemia, but the destabilizing mechanism is poorly understood.
