Outcomes and toxicities of definitive radiotherapy and reirradiation using 3‐dimensional conformal or intensity‐modulated (pencil beam) proton therapy for patients with nasal cavity and paranasal sinus malignancies

Abstract

PT achieved remarkable LC for patients with nasal cavity and paranasal sinus cancers with lower grade 3 toxicities relative to historical reports. IMPT has the potential to improve the therapeutic ratio in these malignancies and is worthy of further investigation.
