鼻咽癌颈部淋巴结转移与鼻咽病灶的关系

收集了鼻咽癌伴颈部淋巴结转移者２５４例，探讨其咽旁间隙和／或“茎内”受累与颈淋巴结的关系。结果表明：咽旁间隙或“茎内”受累与颈淋巴结转移有关，但与其大小无关；当鼻咽癌仅累及鼻咽一侧时，其颈部淋巴结转移率与受累的鼻咽部位多少无关；双侧“茎内”伴双侧咽旁间隙受累比伴单侧受累更易发生双侧颈淋巴结转移；仅双侧“茎内”受累与同时伴单侧或双侧咽旁间隙受累，两者颈淋巴结转移率无差别；鼻咽双侧受累较单侧受累，其双侧颈淋巴结转移率要高。

The Relationship between Nodal Metastasis and Local Involvement in NPC

This article analyzed the relationship between the involvement of the parapharyngeal space (PS) and/or the soft tissue medial to the styloid process (STMSP) with metastasis of the neck lymph node (NLN).It is concluded that there was correlation between invasion of PS or STMSP and the metastasis of NLN,but none with the size of NLN.Under circumstances when lesion was confined to one side of the nasopharynx,no correlation was noted between metastatic frequency of NLN and the extent of involvement at the nasopharynx.Bilateral NLN metastasis occurred more frequently when bilateral STMSP and PS were invaded than bilateral STMSP but only unilateral PS were invaded.There was no difference of NLN metastatic frequency between bilateral STMSP invasion and unilateral or bilateral PS invasion.The bilateral NLN metastatic frequency of bilateral nasopharyngeal involvement was higher than that of unilateral invasion.
