Prophylactic Radiotherapy Optimization for Enhanced Thyroid Function Protection in NPC
Prophylactic Radiotherapy Optimization for Enhanced Thyroid Function Protection in Nasopharyngeal Carcinoma (PROTECT-NPC): A Multicenter, Non-Inferiority, Open-Label, Randomized Controlled Phase III Clinical Trial
About This Trial
This study is a multicenter, non-inferiority, open-label, randomized controlled Phase III clinical trial. It aims to compare the efficacy of modified delineation radiotherapy (experimental group) versus standard delineation radiotherapy (control group) in the prophylactic irradiation of neck lymphatic drainage areas III/IVa in nasopharyngeal carcinoma. The study evaluates the incidence of primary hypothyroidism, quality of life, and adverse events between the two groups.
