Pseudomembrane Removal for Post-RT Nasopharyngeal Necrosis

Sponsor: Jiangxi Provincial Cancer Hospital

Summary

This study aims to evaluate the effectiveness and safety of endoscopic nasopharyngeal pseudomembrane removal in reducing radiation-induced nasopharyngeal necrosis in patients with recurrent nasopharyngeal carcinoma who have received re-irradiation. This is a prospective, single-arm, multicenter interventional study. Participants with recurrent nasopharyngeal carcinoma who develop pseudomembrane reaction during or after re-irradiation will receive endoscopic pseudomembrane removal. Based on published literature, the 2-year incidence of radiation-induced nasopharyngeal necrosis after re-irradiation is approximately 40%. This study expects to reduce the incidence to 20%. The primary outcome measure is the 2-year incidence of nasopharyngeal necrosis after re-irradiation. Secondary outcome measures include: necrosis-free survival, overall survival, progression-free survival, local regional recurrence-free survival, distant metastasis-free survival, as well as safety and adverse events. A total of 40 participants will be enrolled from multiple hospitals in China.
