Fumito Ito, MD, PhD, joined the faculty of Roswell Park Cancer Institute in 2015 and is an Associate Professor of Oncology in the Department of Surgical Oncology and the Center for Immunotherapy. He is also an Associate Professor of Surgery, Jacobs School of Medicine and Biomedical Sciences, State University of New York at Buffalo.
After earning his medical degree from the Shiga University, Japan, Dr. Ito completed his postgraduate training in Surgery at the Shiga University Hospital, Japan. Dr. Ito then completed a research fellowship in Tumor Immunology at the University of Michigan and earned his PhD from the Shiga University, Japan. From 2003 to 2010, Dr. Ito completed his surgery residency training at the University of Wisconsin and surgical oncology fellowship training at the Roswell Park Cancer Institute. He then served as an Assistant Professor in the Department of Surgery at the University of Michigan before returning to the Roswell Park Cancer Institute in 2015.
Dr. Ito is licensed by New York State and certified in General Surgery by the American Board of Surgery.
He has a significant clinical interest in melanoma, sarcoma, breast and gastrointestinal cancer. Dr. Ito’s research interests include the development of novel cancer immunotherapy using pluripotent stem cells, and the use of genome-engineering technology to augment anti-cancer responses, and elucidate the immunomodulatory mechanisms of ablative techniques such as radiofrequency and cryoablation.
Dr. Ito is a member of the American College of Surgeons, the Society of Surgical Oncology, the Central Surgical Association, the American Association for Cancer Research, the American Association of Immunologists, and the Society of Thermal Medicine.
Adoptive cell therapy with autologous tumor-infiltrating lymphocytes (TILs) has emerged as one of the most effective treatments for patients with metastatic melanoma. A major limitation of this approach is poor survival of T cells in vivo following infusion. This limitation of adoptive cell therapy can be overcome by using induced pluripotent stem cells (iPSCs) that self-renew, maintain pluripotency, and provide an unlimited source of autologous T cells for immunotherapy.
In 2011, Dr. Ito gained expertise in generating iPSCs from T cells in collaboration with Dr. Shinya Yamanaka, the 2012 Nobel Laureate in Medicine and Physiology, who discovered groundbreaking reprogramming technology.
Dr. Ito has recently reported successful generation of human iPSCs from melanoma TILs, and is currently investigating safety and therapeutic efficacy of pluripotent stem cell-derived T cells.
