鼻咽癌颈部淋巴结转移与鼻咽灶的关系

The relationship between the cervical node metastasis and primary site of nasopharyngeal carcinoma

收集并分析了疗前鼻咽癌伴颈淋巴结转移者 2 5 4例 ,探讨其咽旁间隙和 /或“茎内”受界与颈淋巴结的关系。结果 本组鼻咽癌单侧颈淋巴结转移率 78.35 % ,双侧者 2 1.6 5 %。“茎内”和咽旁间隙受累与颈淋巴结转移有关 ,但与其大小无关。鼻咽癌仅累及鼻咽一侧时 ,颈淋巴结转移与侵犯鼻咽部位多少无关 ;双侧“茎内”受界与同时伴单侧或双侧咽旁间隙受累 ,两者颈林巴结转移率无差别。鼻咽癌累及双侧“茎内”合并单侧咽旁间隙受累比合并双侧咽旁间隙受累 ,其单侧颈淋巴结转移率较高 ,双侧颈淋巴结转移率较低 ,而双侧“茎内”或咽旁间隙受累比单侧“茎内”或咽旁间隙受累 。

In order to explore the relationship between the involvement of lateropharyngeal space and cervical node metastasis, 254 cases of pre-treatment nasopharyngeal carcinoma patients with cervical node metastasis were involved in the present study. The results showed that unilateral cervical node metastasis rate was 78.35%, while bilateral metastasis rate was 21.65%. The involvement of lateropharyngeal space was related to the cervical node metastasis but not the sizes.
