Long-term outcomes of intensity-modulated radiotherapy for 868 patients with nasopharyngeal carcinoma: An analysis of survival and treatment toxicities

IMRT for NPC yielded excellent survival outcomes, and distant metastasis was the most commonly seen failure pattern after treatment. The role of concurrent chemotherapy for advanced locoregional stage NPC patients needs to be further investigated. Treatment-related toxicities were well tolerable. However, the incidence of brain radiation damage was relatively high, especially for patients with advanced T-stage.
