Risk analysis in radiation therapy: State of the art

Five radiotherapy accidents, from which two serial, occurred in France from 2003 to 2007, led the authorities to establish a roadmap for securing radiotherapy. By analogy with industrial processes, a technical decision form the French Nuclear Safety Authority in 2008 requires radiotherapy professionals to conduct analyzes of risks to patients. The process of risk analysis had been tested in three pilot centers, before the occurrence of accidents, with the creation of cells feedback. The regulation now requires all radiotherapy services to have similar structures to collect precursor events, incidents and accidents, to perform analyzes following rigorous methods and to initiate corrective actions. At the same time, it is also required to conduct analyzes a priori, less intuitive, and usually require the help of a quality engineer, with the aim of reducing risk. The progressive implementation of these devices is part of an overall policy to improve the quality of radiotherapy. Since 2007, no radiotherapy accident was reported.
