study shows promise of combining radiation therapy with dendritic cell vaccines for breast cancer

Sumary of Study shows promise of combining radiation therapy with dendritic-cell vaccines for breast cancer:

  • A research team led by Fumito Ito, MD, PhD, FACS, of Roswell Park Comprehensive Cancer Center reports new data on the promise of combining standard treatment for breast cancer with a particular form of cancer immmunotherapy -;
  • This study, published in the Journal for ImmunoTherapy of Cancer, is the first to demonstrate that in situ dendritic-cell vaccines can improve the effectiveness of radiation therapy for some aggressive and treatment-resistant forms of breast cancer.
  • “Although immunotherapy with primary conventional dendritic cells is a promising approach, obtaining a sufficient number of circulating conventional dendritic cells has proved difficult,” says Dr. Ito, who is Associate Professor of Surgical Oncology at Roswell Park.
  • Use of induced pluripotent stem cells (iPSCs) has been proposed to overcome that limitation, but the feasibility of this approach had not previously been demonstrated.
  • Related StoriesThe team’s results show that intratumoral administration of iPSC-DCs significantly enhanced antitumor efficacy of local irradiation, which is commonly incorporated into treatment plans for patients with breast cancer.
  • And we saw evidence of systemic tumor-specific immunological memory, suggesting a potential for long-term tumor control,” says Dr. Ito.
