PBX3 and acute myeloid leukemia: No such correlation was found, on the other hand there was no PBX3-overexpressing patient among AML patients within the prognostically favourable subgroup (0/6 cases from prognostically favourable versus 26/46 cases from prognostically intermediate or adverse subgroup overexpress PBX3, 0% versus 57% respectively, P = 0.02).
