title: Treatment with heavy charged particles: systematic review of clinical data and current clinical (comparative) trials.
abstract: BACKGROUND
  To analyze relevant data on carbon ion radiotherapy for different tumor indications and to review current clinical trials.
  
  
  METHODS
  All published data on carbon ion radiotherapy were searched for with specific criteria in PUBMED. The terms for search were 'carbon ion and (radiotherapy OR radiation therapy) and (nirs OR chiba OR japan OR itep OR st. petersburg OR PSI OR dubna OR uppsala OR clatterbridge OR loma linda OR nice OR orsay OR itemba OR mpri OR himac OR triumf OR GSI OR HMI OR NCC OR ibmc OR pmrc OR MGH OR infn-lns OR shizuoka OR werc OR zibo OR md anderson OR fpti OR ncc ilsan OR boston OR heidelberg OR tsukuba) NOT in vitro NOT cell culture NOT review[Publication Type] Filters: Humans, English'. The search delivered 273 hits, of which only articles in English including 20 or more patients were included. Case reports were not considered. We subdivided into disease- and site-specific groups.
  
  
  CONCLUSIONS
  To date, several studies have been performed, however, no randomized trials have been conducted. Therefore, carbon ion radiotherapy must be considered an experimental treatment, and randomized trials comparing modern photon as well as proton treatments are necessary.
