Nasopharyngeal carcinoma is endemic in Asia and is etiologically associated with Epstein-Barr virus. Radiotherapy is the primary treatment modality. The role of systemic therapy has become more prominent. Based on multiple phase III studies and meta-analyses, concurrent cisplatin-based chemoradiotherapy is the current standard of care for locally advanced disease (American Joint Committee on Cancer manual [7th edition] stages II-IVb). The reported failure-free survival rates from phase II trials are encouraging for induction + concurrent chemoradiotherapy. Data from ongoing phase III trials comparing induction + concurrent chemoradiotherapy with concurrent chemoradiotherapy will validate the results of these phase II studies. Intensity-modulated radiotherapy techniques are recommended if the resources are available. Locoregional control exceeding 90% and reduced xerostomia-related toxicities can now be achieved using intensity-modulated radiotherapy, although distant control remains the most pressing research problem. The promising results of targeted therapy and Epstein-Barr virus-specific immunotherapy from early clinical trials should be validated in phase III clinical trials. New technology, more effective and less toxic chemotherapy regimens, and targeted therapy offer new opportunities for treating nasopharyngeal carcinoma.
鼻咽癌在亚洲为地方性疾病,病因与 Epstein-Barr 病毒相关。放射治疗是主要的治疗方式。全身治疗的作用愈发突出。基于多项 III 期研究和荟萃分析,以顺铂为基础的同步放化疗是目前局部晚期疾病(美国癌症联合委员会手册[第 7 版]II-IVb 期)的标准治疗方案。II 期试验报道的诱导 + 同步放化疗的无病生存率令人鼓舞。正在进行的比较诱导 + 同步放化疗与同步放化疗的 III 期试验数据将验证这些 II 期研究的结果。若资源可用,推荐采用调强放射治疗技术。尽管远处控制仍然是最紧迫的研究问题,但使用调强放射治疗目前可实现超过 90%的局部区域控制并降低口干相关毒性。早期临床试验中靶向治疗和 Epstein-Barr 病毒特异性免疫治疗的喜人结果应在 III 期临床试验中得到验证。新技术、更有效且毒性更小的化疗方案以及靶向治疗为鼻咽癌的治疗提供了新机遇。
