We investigated the incidence of level I metastasis in patients with laryngeal and hypopharyngeal squamous cell carcinoma (SCC).
The records of 126 patients who underwent primary tumor excision with radical neck dissection (RND) or its modifications for laryngeal or hypopharyngeal SCC were retrospectively reviewed. Preoperative tumor and neck stages, the sites and the number of metastatic lymph nodes were recorded. Patients treated with selective neck dissection (SND) or preoperative chemotherapy and/or radiation therapy were excluded.
Of 155 RND or modified RND performed for 113 laryngeal and 13 hypopharyngeal SCC, lymph node metastases were detected in 51 specimens, all of which spared level I. The most frequently involved levels were II and III.
Selective neck dissection sparing level I may be appropriate for clinically and radiologically N0 patients with laryngopharyngeal carcinoma.
我们调查了喉和下咽鳞状细胞癌（SCC）患者I区转移的发生率。
回顾性分析126例行原发性肿瘤切除并根治性颈清扫术（RND）或其改良术式治疗喉或下咽SCC患者的病历。记录术前肿瘤和颈部分期、转移淋巴结的部位及数量。排除接受选择性颈清扫术（SND）或术前化疗和/或放疗的患者。
对113例喉SCC和13例下咽SCC患者进行了155例RND或改良RND，在51个标本中检测到淋巴结转移，所有标本均未累及I区。最常受累的区域是II区和III区。
对于临床和影像学检查为N0的喉咽癌患者，保留I区的选择性颈清扫术可能是合适的。
