January 21, 2014 — Three prostate cancer patients were among the first to receive treatment at the Provision Center for Proton Therapy in Knoxville, Tenn., the state’s first proton therapy center.
14 centers in the United States and 46 in the world offer the non-invasive and precise radiotherapy that uses a single beam of high-energy protons to treat various forms of cancer including prostate, pediatric, sarcoma, brain, lung and breast cancers. Proton beams can be within millimeters of accuracy to deliver maximum energy in a controlled range of cancerous tumors.
Provision Medical Director Marcio Fagundes, M.D., performed the treatments for two Knoxville residents and a North Carolinian. A board-certified radiation oncologist, Dr. Fagundes began treating patients with proton therapy at Harvard Medical School in 1993.
Provision Center for Proton Therapy will have three treatment rooms and capacity to treat up to 900 cancer patients annually. Treatments will typically require daily 30 to 45 minute sessions for two months.
