In univariate analyses, age (≥10 years), white blood cell counts (>100 × 10(9)/l), t(9;22)(q34;q11), MLL rearrangements, near-haploidy and deletions of ATP10A, IKZF1, SPRED1 and the pseudoautosomal 1 regions on Xp/Yp were significantly associated with decreased 10-year event-free survival, with IKZF1 abnormalities being an independent risk factor in multivariate analysis irrespective of the risk group.
