Hematopoietic Cell Transplant for Blastic Plasmacytoid Dendritic Cell Neoplasm

Abstract

Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare aggressive hematologic malignancy derived from precursors of plasmacytoid dendritic cells. Historically, BPDCN has had few available treatment options and a poor prognosis. The emergence of novel targeted therapies, namely tagraxofusp, has changed the treatment landscape of BPDCN, but data are lacking regarding the long-term durability of responses. Despite absence of randomized data, allogeneic hematopoietic cell transplant has become the de facto option for patients with BPDCN who achieve a first complete remission. As new therapies continue to emerge, it will be important to evaluate the role of postallograft maintenance/consolidation.
