Abstract |
Radiotherapy (RT), alone or combined with surgery and/or chemotherapy is given to almost all head and neck cancer (HNC). The goal of RT is to increase as much as possible the dose in the tumor to cure the patient, while limiting the dose in the organs at risk, mainly the parotids gland to limit the xerostomia. HNC RT appears particularly challenging due to the complexity of the shape of the anatomical structures, which also changes during the 7 weeks of treatment. Advances in imaging-modalities, -processing and -integration at the different RT steps have been crucial to develop a new image and dose-guided adaptive RT (ART) strategy. Moreover, the integration of functional imaging such as FDG-PET (performed before and during the treatment) leads to an even more highly targeted and dose-escalated ART. This article is an overview of the place and role of imaging at the different steps of HNCART, from a medical point of view.
