Clinical features, immune profile and induction chemotherapy options for blastic plasmacytoid dendritic cell neoplasm: a systematic review and meta-analysis

Abstract

Aim: Blastic plasmacytoid dendritic cell neoplasm is a rarely occurring hematologic malignancy with a dismal prognosis. Methods: We conducted a meta-analysis for a total of 1312 patients from 24 retrospective studies. Results: The complete remission (CR) rate of acute lymphoblastic leukemia-like induction chemotherapy was 82%, and the overall survival (OS) was 15.75 months; the CR rate of acute myeloid leukemia-like chemotherapy was 51%, and the OS was 7.18 months; and the CR rate of cyclophosphamide, doxorubicin, vincristine and prednisone-like chemotherapy was 50%, and the OS was 12.06 months. Conclusion: Acute lymphoblastic leukemia-like induction chemotherapy has the best CR rate and OS.
