Durability of the parotid‐sparing effect of intensity‐modulated radiotherapy (<scp>IMRT</scp>) in early stage nasopharyngeal carcinoma: A 15‐year follow‐up of a randomized prospective study of <scp>IMRT</scp> versus two‐dimensional radiotherapy

Abstract

The parotid-sparing effect of IMRT in NPC treatment is durable, with significantly less physician- and patient-scored xerostomia at 15 years. IMRT results in better long-term survival and fewer SLCs.
