[Radiotherapy of invasive breast cancer: French national guidelines]

The French National Cancer Institute (INCa) and Société française de sénologie et pathologie mammaire (SFSPM), in collaboration with a multidisciplinary experts group, have published the French national clinical practice guidelines on a selection of 11 currently debated questions regarding the management of invasive breast cancer. Those guidelines are based on a comprehensive analysis of the current published evidence dealing with those issues, secondly reviewed by 100 reviewers. Radiotherapy was concerned by five of the 11 questions: indications for the boost after whole gland irradiation; hypofractionated radiotherapy; partial breast irradiation; indications for mammary internal nodes irradiation, and indications of radiotherapy after neo-adjuvant chemotherapy.
