Introduction: Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare and aggressive myeloid malignancy that contributes to <1% of all hematologic neoplasms. Before the introduction of various targeted agents, the therapeutic approach was based on regimens used for acute lymphoblastic or myeloid leukemia and non-Hodgkin's lymphoma (e.g. hyperCVAD (hyperfractionated cyclophosphamide, vincristine, doxorubicin and dexamethasone alternating with high dose methotrexate and cytarabine) and CHOP(cyclophosphamide, doxorubicin, vincristine, prednisone) -based regimens) followed by allogeneic stem cell transplantation for eligible patients. Given that this disease primarily affects older patients, there is a significant barrier to using these highly toxic regimens, even though these regimens are usually associated with the most durable responseAreas covered: In this review, we briefly discuss outcomes with the use of leukemia-based induction regimens as well as the use of stem cell transplant. We also review low-intensity chemotherapeutic regimens. Finally, we will describe both preclinical and early clinical data regarding novel targeted strategies for treating BPDCN without the use of cytotoxic chemotherapy, with a focus on the use of CD123 directed therapy.Expert opinion: While the current standard treatment for BPDCN is acute leukemia-based regimen followed by hematopoietic stem cell transplantation for transplant-eligible patients, there are very promising results for CD123 directed therapies. The future of BPDCN treatment may include targeted therapies without the need for cytotoxic chemotherapy.
