| Popis: | We retrospectively assessed whether normalized bone marrow WT1 levels could be used for risk stratification in a consecutive series of 584 acute myeloid leukemia (AML) patients. A cutoff value of 5065 copies at diagnosis identified two prognostic groups (overall survival (OS): 44 +/- 3 vs 36 +/- 3%, P = 0.023; leukemia-free survival (LFS): 47 +/- 3 vs 36 +/- 4%, P = 0.038; and cumulative incidence of relapse (CIR): 37 +/- 3 vs 47 +/- 4%, P = 0.043). Three groups were identified on the basis of WT1 levels post-induction: Group 0 (WT1 between 0 and 17.5 copies, 134 patients, OS: 59 +/- 4%, LFS: 59 +/- 4% and CIR: 26 +/- 4%); Group 1 (WT1 between 17.6 and 170.5 copies, 160 patients, OS: 48 +/- 5%, LFS: 41 +/- 4% and CIR: 45 +/- 4%); and Group 2 (WT1 > 170.5 copies, 71 patients, OS: 23 +/- 6%, LFS: 19 +/- 7% and CIR: 68 +/- 8%) (P 100 copies (47 patients, 16%); an intermediate group of patients with WT1 between 10 and 100 copies (148 patients, 52%); and a third group with WT1 o10 copies (92 patients, 32%). Outcomes differed significantly in terms of OS (30 +/- 7%, 59 +/- 4%, 72 +/- 5%), LFS (24 +/- 7%, 46 +/- 4%, 65 +/- 5%) and relapse probability (CIR 72 +/- 7%, 45 +/- 4%, 25 +/- 5%), all P |
