Esthesioneuroblastoma is an uncommon tumor that presents in the sinonasal cavity and anterior skull base. Cervical metastases are not frequently found on initial presentation but eventually occur in 20-25% of these patients. This presents the treating physician with the difficult decision as to how and when to treat the neck in this disease. The aims of this study were to provide a comprehensive review of the incidence of N+ disease at presentation, make recommendations about the optimal treatment strategy of patients with N+ disease, explain the role of elective neck treatment in patients with N0 disease, and comment on treatment of patients with late cervical metastases that require salvage therapy, using the literature review of the incidence and treatment of neck disease in patients with esthesioneuroblastoma. This review revealed an approximately 5-8% incidence of cervical nodal metastasis at the time of presentation. Combined modality therapy with surgery and radiotherapy is recommended to treat the N+ neck at the time of diagnosis and later. Chemotherapy may have a role combined with radiation treatment, but there are little data to support this. There is limited evidence to substantiate the use of elective neck dissection or elective radiotherapy in the clinically and radiologically N0 neck. Patients who have late cervical metastases have a clear survival advantage (59 vs. 14%) when treated with combined surgery and radiotherapy relative to single modality methods alone. The results indicate that the management of the neck in esthesioneuroblastoma continues to be a significant challenge in the treatment algorithm of these complex patients.
嗅神经母细胞瘤是一种罕见的肿瘤,发生于鼻窦和颅前窝。在初始表现时,颈部转移并不常见,但最终会出现在 20-25%的患者中。这给治疗医生带来了一个难题,即如何以及何时治疗这种疾病的颈部。本研究的目的是全面回顾初诊时 N+疾病的发生率,对 N+疾病患者的最佳治疗策略提出建议,解释 N0 疾病患者选择性颈部治疗的作用,并对需要挽救治疗的晚期颈部转移患者的治疗进行评论,方法是对嗅神经母细胞瘤患者颈部疾病的发生率和治疗进行文献复习。该综述显示,初诊时颈部淋巴结转移的发生率约为 5-8%。建议在诊断时和以后联合手术和放疗对 N+颈部进行综合治疗。化疗可能与放疗联合使用,但数据很少支持这一点。在临床和放射学上 N0 颈部,选择性颈清扫术或选择性放疗的应用尚无充分证据支持。与单一治疗方法相比,接受联合手术和放疗的晚期颈转移患者的生存优势明显(59%比 14%)。结果表明,在这些复杂患者的治疗方案中,嗅神经母细胞瘤颈部的管理仍然是一个重大挑战。
