Rieder et al. reported for the first time in 995 that dic(9;2 0) (p1 1–13; q1 1) is a non-randomized chromosomal abnormality in acute lymphoblastic leukemia (ALL), of which only 17 have been reported so far. In this paper, 20 new cases were reported and it was confirmed that dic ( 9; 20) is a new cytogenetic type of ALL. Leukemia Research Foundation / Cancer Cell Genetics UK (LRF/UKCCG)
