Abstract
INTRODUCTION: New radiation therapy techniques seek to adapt dose distribution to three-dimensional tumor geometry, so as to deliver the lowest possible dose to normal tissue and at-risk organs. This is expected to enhance locoregional control and survival and to reduce complications and thereby improve quality of life. Post-radiation xerostomia significantly deteriorates quality of life. MATERIAL AND METHODS: New external radiation techniques (such as intensity-modulated conformal radiation therapy, RapidArc VMAT arc therapy, tomotherapy, CyberKnife(®), protontherapy, use of carbon ions) applicable in ENT are reviewed. RESULTS: Preliminary data show interesting results in terms of salivary function with highly conformal techniques. CONCLUSION: In France, assessment is ongoing, financed under the Health Ministry's "Support for Expensive Innovatory Techniques" scheme (STIC [Soutien aux techniques innovantes coûteuses]), as routine use is growing rapidly.
