Impact of Epigenomic Hypermethylation at TP53 on Allogeneic Hematopoietic Cell Transplantation Outcomes for Myelodysplastic Syndromes.

ABSTRACT: Myelodysplastic syndromes (MDS) are a heterogeneous group of hematopoietic stem cell disorders for which allogeneic hematopoietic cell transplantation (HCT) is currently the sole curative treatment. Epigenetic lesions are considered a major pathogenetic determinant in many cancers, and in MDS, epigenetic-based interventions have emerged as life-prolonging therapies. However, the impact of epigenomic aberrations on HCT outcomes among patients with MDS are not well understood. We hypothesized that epigenomic signatures in MDS patients before undergoing HCT serve as a novel prognostic indicator of the risk of post-HCT MDS relapse. To evaluate these epigenomic signatures in MDS patients, we analyzed reduced representation bisulfite sequencing profiles in a matched case-control population of 94
