Results of radiation therapy for nasopharyngeal carcinoma (locoregional
control and survival) are usually reported by T stage and N stage separately or
by specific T and N subgroupings rather than by numerical stages I to IV.
Outcome also depends on a variety of biologic and technical factors related to
