目的　探讨声门上型喉癌颈淋巴结隐匿性转移的病理特点和规律 ,帮助临床治疗。方法　对 10 0例临床N0 的声门上型喉癌患者和颈廓清标本 ( 153侧 )进行连续切片 ,光镜观察。结果　隐匿性转移率为 38%。发现转移淋巴结 51个 :Ⅰ区 1个 ( 2 % )、Ⅱ区 37个 ( 73% )、Ⅲ区 12个 ( 2 3% )、Ⅳ区1个 ( 2 % )。转移淋巴结的长径 0 5- 2 6cm ,平均为 1 1cm。 51个淋巴结中 ,癌早期 2 1个 ( 4 1% )、癌长期 18个( 35% )、癌满期 7个 ( 14% )、破膜期 5个 ( 10 % )。结论　声门上型喉癌颈淋巴结的隐匿性转移率高 ,早期不易诊断 ,应积极行选择性颈廓清术。 Objective To investigate the pathological features and rules of occult metastasis of supraglottic cervical lymph nodes and to help clinical treatment. Methods One hundred and ten patients with clinically N0 supraglottic laryngeal carcinoma and a clear neck (153 sides) were serially sectioned and observed with light microscope. Results The occult metastasis rate was 38%. Fifty-one lymph node metastases were found in this group, including one in grade Ⅰ (2%), 37 in grade Ⅱ (73%), 12 in grade Ⅲ (23%) and one in grade Ⅳ (2%). Longitudinal diameter of metastatic lymph nodes 0 5- 2 6cm, an average of 1 1cm. Of the 51 lymph nodes, 21 were early (41%), 18 were long (35%), 7 were dead (14%) and 5 (10%) were ruptured. Conclusions The cervical lymph node of supraglottic laryngeal carcinoma has a high occult metastatic rate. It is not easy to diagnose early and should undergo selective neck dissection.
