Brief Summary:
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.
Detailed Description:
The newly diagnosed non-metastatic nasopharyngeal carcinoma has shown satisfactory therapeutic effect under the intensity modulated radiation. The 5-year survival rate of the newly diagnosed Ⅰ nasopharyngeal carcinoma was more than 95%. However, mos patients receiving radical radiotherapy will experience different degrees of acute or chronic radiation injury, which will affect the quality of life of patients to varying degrees. For stage Ⅰ nasopharyngeal carcinoma with primary lesion confined to nasopharyngeal mucosa and without regional lymph node metastasis, in theory, the primary lesion can be removed by minimally invasive surgery without need of preventive treatment of cervical lymph nodes according to the prior study.
Based on our previous research results, we stratified the nasopharyngeal primary tumor diameter of stage Ⅰ nasopharyngeal carcinoma by whether the short diameter of retropharyngeal lymph nodes and neck lymph nodes was smaller than 0.4cm and 0.6cm respectively, and the tumor diameter of nasopharyngeal primary tumor was ≤ 1.5cm. This study evaluated the efficacy and safety of endoscopic minimally invasive surgery compared to conventional intensity-modulated radiotherapy for these stage Ⅰ nasopharyngeal carcinoma.
In this study, the stage Ⅰ patients in the experimental group only received endoscopic nasopharynx resection and were followed up closely to monitor the recurrence and distant metastasis of the tumor.
The patients in the control group received conventional intensity-modulated radiotherapy and regular follow-up. The target area and dose of radiotherapy were as follows: GTVnx: primary lesion of the nasopharynx; CTV1: high-risk area and the entire nasopharynx; CTV2: low-risk area. The recommended intensity-modulated radiotherapy dose is GTVnx(69.96 Gy/33 Fr/2.12 Gy); CTV1(60.60 Gy/33 Fr/1.82 Gy); CTV2(54.12 Gy/33 Fr/1.64 Gy).
