Reirradiation with intensity‐modulated radiotherapy for locally recurrent T3 to T4 nasopharyngeal carcinoma

Abstract

Adequate tumor dose coverage was important for treating rT3 to rT4 NPC. Although late complications were common, treatment-related mortality was solely vascular in nature. Dose constraints of neurologic structures for reirradiation should be revised with the latest information on late toxicities. © 2016 Wiley Periodicals, Inc. Head Neck 39: 533-540, 2017.
