Endoscopic Surgery Compared With Intensity Modulated Radiotherapy for Stage I Nasopharyngeal Carcinoma : A Multicenter, Randomized Controlled Clinical Trial.
The goal of this clinical trial is to compare the survival and adverse reactions differences between endoscopic surgery and intensity modulated radiotherapy for patients with newly diagnosed stage Ⅰ nasopharyngeal carcinoma, aiming to verifying the efficacy and safety of endoscopic surgery for stage Ⅰ nasopharyngeal carcinoma.

• Non-keratinized carcinoma of the nasopharynx (differentiated or undifferentiated, i.e., WHO type II or III) or carcinoma in situ confirmed histologically and/or cytologically.
• According to the eighth edition of UICC/AJCC staging, the patient was defined as T1N0M0 stage I.
• The maximum short diameters of retropharyngeal lymph nodes and cervical lymph nodes were not more than 0.4cm and 0.6cm respectively, or retropharyngeal lymph nodes and cervical lymph nodes were 0.4-0.5cm and 0.6-1.0cm respectively but PET/CT showed negative.
