Conclusions: NAPT survey data

  • The number of patients treated with protons is gradually but steadily increasing –

approximately 7,850 patients were treated with protons in the US in 2015

  • The number of patients treated for “traditional” indications for protons –

pediatrics, brain – continues to gradually increase, although there has been minimal increase in base of skull tumors, and intraocular melanoma.

  • There is a shift to “new” disease sites treated, especially with an increase in breast,

lung, head & neck, gastrointestinal tumors

  • The total number of patients with prostate cancer has remained relatively stable
  • Despite additional new centers
  • Relative frequency has decreased from 43.4% in 2012 to 29.4% in 2015
  • Complexity of treatments in gradually increasing over time (especially

intermediate)

  • Not listed - retreatment – this may be substantial number of patients
  • Strong trend toward pencil beam scanning, away from US or DS
