This paper reports clinical and cytogenetic data from 125 cases with t(9;11)(p21-22;q32) which were accepted for a European Union Concerted Action Workshop on 11q23. This chromosome abnormality is known to occur predominantly in acute myeloid leukemia (AML) FAB type M5a and less often in AML M4; in this series it was also found to occur, uncommonly, in other AML FAB types, in childhood acute lymphoblastic leukemia (ALL) (nine cases), in relatively young patients with myelodysplastic syndrome (MDS) (five cases), acute biphenotypic leukemia (two cases), and acute undifferentiated leukemia (one case). All age groups were represented but 50% of the patients were aged less than 15 years. The t(9;11) was the sole abnormality in 57 cases with AML; trisomy 8 was the most common additional abnormality (23 cases, including seven with further abnormalities), and 28 cases had other additional abnormalities. Among the t(9;11)+ve patients with AML, the white cell count (WBC) and age group were significant predictors of event-free survival; central nervous system (CNS) involvement or karyotype class (sole, with trisomy 8, or with other), also contributed to prognosis although our data could not show these to be independent factors. The best outcome was for patients aged 1-9 years, with low WBC, and with absence of CNS disease or presence of trisomy 8. For patients aged less than 15 years, the event-free survival for ALL patients was not significantly worse than that of AML patients.
