Proton Patients Reach 55,000 Worldwide

The number of cancer patients treated with proton beam radiation therapy
continues to climb worldwide as more proton facilities become operational.
The Particle Therapy Co-operative Group (PTCOG), an organization of scientists,
medical physicists, physicians, and radiation researchers, reported that about 55,000 patients worldwide had been treated with proton therapy. This includes about
18,000 in the United States treated at five operating centers. A majority were treated
at Loma Linda University Medical Center that opened the first hospital-based proton
center in 1990.
