Официальное название
Endoscopic Nasopharyngectomy Combined with Retropharyngeal Lymph Node Dissection Plus Low-dose Radiotherapy Versus Bilateral Upper Neck Dissection for Newly Diagnosed Stage I Nasopharyngeal Carcinoma: a Randomized Controlled Clinical Trial
Обзор
The goal of this clinical trial is to compare the efficacy and safety of endoscopic nasopharyngectomy combined with retropharyngeal lymph nodes dissection plus bilateral upper neck lymph node dissection or plus postoperative low-dose radiotherapy in newly diagnosed stage Ⅰ nasopharyngeal carcinoma.
Подробное описание
At present, the newly diagnosed non metastatic nasopharyngeal carcinoma has achieved good therapeutic effect under the treatment scheme of intensity modulated radiotherapy. The 5-year survival rate of the newly diagnosed stage Ⅰ nasopharyngeal carcinoma was more than 95%. But at the same time, all 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 the primary lesion confined to the nasopharyngeal mucosa and without regional lymph node metastasis, in theory, the primary lesion can be removed by minimally invasive surgery without preventive treatment of cervical lymph nodes.
Our previous research results showed that endoscopic surgery could achieved similar survival outcomes but less adverse events than radiotherapy for Stage Ⅰ nasopharyngeal carcinoma with short diameter of retropharyngeal lymph nodes\<0.4cm or short diameter of cervical lymph nodes\<0.6 and negative PET/CT findings. However, if there is the same results for all stage I NPC patients is still unclear. Therefore, this study aims to compare the efficacy and safety of endoscopic nasopharyngectomy combined with retropharyngeal lymph node dissection combined with low-dose radiotherapy or bilateral upper neck lymph node dissection compared with conventional intensity-modulated radiotherapy.
When the patients participated in this study, the stage ⅠNPC patient of experimental group 1 received endoscopic nasopharyngectomy combined with retropharyngeal lymph node dissection and low-dose radiotherapy. Low dose radiotherapy target area: CTV1 (tumor bed area); For the primary lesion with negative margin but less than 3mm, the margin area should be included; For patients with extracapsular invasion of lymph nodes, the extracapsular invasion area should be included; It should also include all cervical lymph nodes located above the cricoid cartilage detected by CT/MRI, regardless of size; CTV2: low risk infiltration area. The prescription dose of intensity modulated radiotherapy: CTV1:36.00gy/15fr/2.40gy; CTV2:30.00gy/15fr/2.00gy. The patients in the stage Ⅰ in the experimental group 2 underwent endoscopic nasopharynx resection combined with retropharyngeal lymph node resection and bilateral upper neck lymph node dissection, without radiotherapy or chemotherapy after surgery.
