[Development and perspectives of brachytherapy in France].

During the last decade, the organization of brachytherapy in France moved to 62 units in 173 radiotherapy centres in 2009. More than 7500 patients were treated in 2009, quite exclusively with curative intent, for 80% in public or associated hospitals. The techniques improved to high tech 3D dosimetry and optimization of the dose distribution. Brachytherapy, despite representing only 5% of the treatments by irradiation, is a reference treatment for several tumors.
