目的:研究梨状窝癌颈淋巴结对侧转移的相关因素。方法:收集1993年10月~1999年10月同期行颈廓清术53例梨状窝癌,术后颈廓清标本采用透明淋巴结摘出连续切片法,观察颈淋巴结转移状况,再通过随访资料,分析肿瘤对侧转移与临床病理因素及同侧颈淋巴结转移状况的关系。结果:53例梨状窝癌颈淋巴结转移率为79.2%,对侧颈淋巴结转移率为35.8%。对侧转移与临床N分级、病理分化程度、同侧转移淋巴结中融合转移及破膜转移密切相关。结论:对于N2~3病例及肿瘤分化程度中、低病例,或者同侧转移淋巴结发现融合转移及破膜转移,都应该积极地作肿瘤对侧颈廓清术。
Objective: To study the related factors of contralateral metastasis of cervical lymph nodes in pear-shaped litter. Methods: From January 1993 to October 1999, 53 cases of cervical fossa carcinoma of the neck were excised from the same period of time. The clear specimens of neck were collected by serial sections of clear lymph nodes. The metastasis of cervical lymph nodes was observed. Contralateral metastasis and clinicopathological factors and ipsilateral cervical lymph node metastasis status. Results: The rate of cervical lymph node metastasis was 79.2% in 53 cases and 35.8% in the contralateral cervical lymph nodes. Contralateral metastasis and clinical N classification, the degree of pathological differentiation, ipsilateral metastatic lymph node metastasis and metastasis are closely related. Conclusion: For N2 ~ 3 cases and low, moderate or low differentiation of tumor, or ipsilateral lymph node metastasis and conjunctival metastasis were found, should be positive for the contralateral neck neoplasm.
