Cytogenetic profiles were determined by local laboratories using standard methods. NA, not applicable; UPN, unique patient number.
*
FISH positive for BCR/ABL gene rearrangement.
†
FISH positive for TCF3(E2A)-PBX1 gene fusion.
‡
This case had low hypodiploidy (30-39 chromosomes) at diagnosis. FISH analysis at relapse detected loss of the ABL1 and BCR signals consistent with the low hypodiploid clone seen at diagnosis.
