Popis: Background: WBC levels vary widely in AML pts at diagnosis. Together with various cytogenetic and molecular abnormalities, WBC is a main prognostic factor for AML pts. Treatment decisions like need for intrathecal chemotherapy, trial enrollment eligibility, and stem cell transplant (SCT) considerations are often influenced by degree of WBC elevation. Despite such high clinical relevance, there are no standardized WBC-associated groups that improve prognostication and treatment guidance for AML pts. Aims: (1) define clinically relevant WBC level groups associated with outcome, (2) determine if WBC level has an independent prognostic impact in addition to established prognostic features [i.e., 2017 European LeukemiaNet (ELN) genetic-risk classification] and (3) characterize WBC level-associated gene-expression profiles to provide biologic insights into factors influencing WBC levels. Methods: We analyzed clinical and molecular features of 1,121 younger de novo AML pts similarly treated on frontline Cancer and Leukemia Group B/Alliance for Clinical Trials in Oncology protocols. No pt received an allogeneic SCT in 1 st complete remission (CR). Targeted next generation sequencing of 81 cancer- and leukemia-associated genes was done using MiSeq platform. We defined 3 WBC groups: low ( Results: Pts in the high WBC group had higher extramedullary disease burden at diagnosis than pts in the intermediate and low groups (38% vs 29% and 12%, respectively; P Conclusion: The 3 WBC groups we propose offer additional prognostic information for younger AML pts. An intermediate WBC group was associated with better outcome among all pts and in pts included in the ELN Favorable group, especially those with non-CBF-AML. We also showed differences in the metabolic pathways among WBC groups. Our results suggest that the paradigm that all pts who present with a high WBC have a poor prognosis should be re-evaluated, and can help guide therapy decisions for younger AML pts.
