Background To assess the feasibility of elective neck irradiation to level Ⅰb in nasopharyngeal carcinoma (NPC) using intensity-modulated radiation therapy (IMRT).Methods We retrospectively analyzed 1438 patients with newly-diagnosed, non-metastatic and biopsy-proven NPC treated with IMRT.

目的 局部复发是鼻咽癌治疗过程中面临的主要问题之一.即使运用调强放疗联合同步化疗,局部晚期鼻咽癌的局部复发率仍然达20-30%.18F-FDG PET-CT显像能反应肿瘤内部的生物学信息,有研究运用18F-FDG PET-CT引导进行生物调强放疗以改善鼻咽癌治疗效果,但各研究病例数较少、随访时间较短且主要为其他头颈部鳞癌,因此对鼻咽癌的治疗效果需要进一步探讨.还有研究显示,运用同步加速调强放疗(s
