Key Genetic Alterations and Biomarker for Blastic Plasmacytoid Dendritic Cell Neoplasm

BUFFALO, NY - July 7, 2025 – A new #research paper was #published in Volume 16 of Oncotarget on June 17, 2025, titled “Genetic characteristics of blastic plasmacytoid dendritic cell neoplasm: A single institution experience.” In this study, a research team led by first author Fei Fei and corresponding author Michelle Afkhami from the City of Hope Comprehensive Cancer Center investigated a rare and aggressive type of blood cancer called blastic plasmacytoid dendritic cell neoplasm (BPDCN). Their research uncovered frequent mutations in key genes and identified CCDC50 as a potential biomarker for diagnosis and disease monitoring. These findings could help improve how this cancer is detected and treated in the future. BPDCN most often affects older adults and is known for its rapid progression and poor survival rates. The researchers performed genetic sequencing on 21 patients to better understand the disease. They found that two genes, TET2 and ASXL1, were frequently mutated in these patients and were linked to worse survival, especially in those over 65 years old. “Our study revealed that TET2 (57%) and ASXL1 (33%) were the most frequently mutated genes, followed by NRAS (29%), SRSF2 (14%), ZRSR2 (14%), and KMT2D (14%).” The study also discovered that a gene called CCDC50 was expressed at much higher levels in BPDCN samples compared to other blood cancers, such as acute myeloid leukemia and chronic monomyelocytic leukemia. This suggests that CCDC50 may help clinicians distinguish BPDCN from other similar diseases. Importantly, CCDC50 levels dropped significantly in patients whose disease went into remission, highlighting its potential as a tool for tracking disease activity over time. Researchers further observed that patients who received stem cell transplants lived longer than those who did not, reinforcing the importance of this treatment approach. However, BPDCN remains a challenging disease with an overall poor outlook, making these findings an important step toward better care. This research provides new insights into the genetic changes behind BPDCN and points to CCDC50 as a promising marker to improve diagnosis and monitor treatment success. Larger studies will be needed to confirm these results and bring these discoveries closer to use in routine medical practice.
