He was also part of the team that initiated Stereotactic Radiosurgery on Long Island. In the 1990s, he served as Director of Radiation Oncology at the Center for Cancer Care at Sacred Heart Hospital in Allentown, Pennsylvania. In this capacity, he developed a well-respected clinical service—the first to bring advanced treatment to the region, including high-dose rate brachytherapy in 1996, outpatient implant therapy for gynecologic cancer in 1997, intensity-modulated radiation therapy (IMRT) in 1998 and partial breast irradiation in 2002.

In 2004, Dr. Vigneri returned to the North Shore-LIJ Health System, where he served as physician-in-charge at LIJ. He has been active academically, serving as an instructor in radiation therapy at the Mount Sinai School of Medicine, and currently is an assistant professor of radiation oncology at the Albert Einstein School of Medicine. He is a Fellow of the American College of Radiation Oncology, and has been an invited lecturer throughout the Northeast and in South America. Dr. Vigneri has published in nationally-circulated peer-reviewed journals, including the International Journal of Radiation Oncology and the Archives of Surgery. He has also co-authored a chapter in the textbook “Disorders of the Pancreas: Current Issues in Diagnosis and Management.”

Dr. Vigneri’s current interests include personalizing therapy for patients to minimize both short- and long-term side effects. He has extensive experience in treating prostate cancer with both external beam and implant approaches. He has been an early adopter of using high-dose rate brachytherapy in the treatment of gynecological cancers. Since 2002, Dr. Vigneri has been involved with partial breast irradiation (PBI) and was a major contributor to the national MammoSite registry. He was also an early advocate of using IMRT in head and neck cancers. Dr. Vigneri brings his extensive experience to Staten Island University Hospital, and ensures that the department can meet the oncologic needs our community.
