Career Highlights
Dr. Silvia C. Formenti, an international expert in the use of radiation therapy for the treatment of cancer, is Chair of the newly established Department of Radiation Oncology at Weill Cornell Medical College and Radiation Oncologist-in-Chief at New York-Presbyterian/Weill Cornell Medical Center. A prolific researcher, she has published over 180 papers recognized by high impact journals like JAMA, Journal of Clinical Oncology, Lancet Oncology, Science etc.

Research Projects/Interests
During the past twelve years Dr. Formenti has introduced a paradigm shift in radiation biology, by elucidating the role of ionizing radiation on the immune system, and demonstrating efficacy of combining radiotherapy with immunotherapy in solid tumors. She has translated her preclinical work to clinical trials in metastatic breast cancer, lung cancer and melanoma. She has introduced the concept of recovering an immunological equilibrium in metastatic disease, by converting a metastasis into an in situ, individualized vaccine. In the presence of immune checkpoint blockade (anti-CTLA-4, anti-PDL-1) the irradiated tumor becomes an immunogenic hub, similar to a vaccine. Once immunized against one site, the host develops an anti-tumor immune response capable to reject the other metastases. In some patients with metastatic disease refractory to standard treatment the combination of local radiation and immune check point blockade has resulted in durable complete remissions, sustained for years after treatment. Her work has opened a new field of application for radiotherapy, whereby localized radiation can be used as an adjuvant to immunotherapy of solid tumors and lymphomas. Dr. Formenti is funded by grants from NIH, DOD, and Breast Cancer Research Foundation.
