National Observatory of Radiotherapy. Survey report: situation at the end of 2012 and evolution since 2007

This report presents and discusses the results of a survey on French radiotherapy centres to assess the condition of radiotherapy equipment, on the activity of these centres, on the composition of their medical and paramedical radiotherapy staff. After a presentation of the survey organisation and implementation, and of its methodology, results are presented and discussed, generally illustrated by tables and graphs. These results concern technical platforms and equipment (structure of the linear accelerator stock, additional equipment, operation planning and duration, procedures in case of machine stoppage, treatment preparation, equipment for treatment quality control), the activity (number of treated patients, numbers of treatments and sessions, treatment preparation, applied techniques and tumour locations), and the staff (evolution of the numbers of oncologists radiotherapists, medical physicists, technicians, and dosimetry technicians)
