Nasopharyngeal Carcinoma, medial group retropharyngeal node
Brief summary
This is an randomized, controlled, phase 3 clinical trial. The purpose of this study is to evaluate whether medial group retropharyngeal node (MRLN) sparing could reduce the incidence of radiation-caused dysphagia and improve patients' quality of life without compromising survival rate.
Detailed description
In this study, patients with non-keratinizing stage T1-4 N0-3 M0 NPC(UICC/AJCC 8th edition), except for patients with MRLN metastasis, are randomly assigned to receive MRLN sparing or prophylactic irradiation . Patients in MRLN sparing group will not routinely receive MRLN irradiation to 56Gy/33Fr; while patients in MRLN prophylactic irradiation group will always receive MRLN irradiation to 56Gy/33Fr. Our primary endpoint is local relapse-free survival (LRFS). Secondary end points include overall survival (OS), incidence of out-field recurrence rate, toxic effects, and quality of life (QOL).All efficacy analyses are conducted in the intention-to treat population, and the safety population include only patients who receive their randomly assigned treatment.
Interventions
Patients in MRLN sparing group will not routinely receive MRLN irradiation; while patients in MRLN prophylactic irradiation group will always receive MRLN irradiation to 56Gy/33Fr.
