Update of Radiation Techniques Using Photons for Anterior Skull Base Tumors
© 2020 S. Karger AG, Basel..
Anterior skull base tumors represent a challenge for radiation therapy (RT) planning given the close proximity of the target lesion to numerous critical structures in this complex anatomic location. Despite this challenge, surgery followed by postoperative RT is a common treatment paradigm for malignant sinonasal tumors that has been associated with improved outcomes compared to single-modality treatment. Therefore, technological advancements allowing for increasingly conformal target coverage and sparing of organs at risk are important to accomplish the goal of delivering RT with the highest therapeutic ratio possible. Such advances include both intensity-modulated RT and volumetric-modulated arc therapy, which allow RT to be delivered more precisely than ever before. Furthermore, stereotactic radiosurgery can deliver highly conformal doses of external beam RT in a single or limited number of fractions for the definitive or postoperative management of benign lesions of the anterior base of the skull. These sophisticated photon-based RT strategies have allowed for exciting advances in the contemporary treatment of anterior skull base tumors that will continue to improve patient outcomes and reduce toxicity for years to come.
