One hundred and eleven cases of supraglottic squamous cell cancer (T1-4N1) were retrospectively analysed. The result showed that: 1. the 3 years survival rate was 72% (80/111); 2, the rate of contralateral neck node metastasis after ipsilateral RND was 17.9%, and the cases of T3-4 with positive histologic findings of neck dissection samples had a higher rate contralateral neck node metastasis (38.6%); 3, the contralateral neck node metastasis rate (26.1%) in the group with surgery alone was significantly higher than that (7.1%) in the group with preoperative radiation (P < 0.05). The authors draw the conclusion that contralateral neck node metastasis is a high risk factor for recurrence of N1 supraglottic laryngeal cancer and that preoperative radiation may be be useful in controlling subclinical metastasis.
对111例声门上型鳞状细胞癌（T1-4N1）患者进行了回顾性分析。结果显示：1. 3年生存率为72%（80/111）；2. 同侧根治性颈清扫术后对侧颈部淋巴结转移率为17.9%，颈部清扫标本组织学检查阳性的T3-4病例对侧颈部淋巴结转移率更高（38.6%）；3. 单纯手术组的对侧颈部淋巴结转移率（26.1%）显著高于术前放疗组（7.1%）（P<0.05）。作者得出结论，对侧颈部淋巴结转移是N1期声门上型喉癌复发的高危因素，术前放疗可能有助于控制亚临床转移。
