摘要:

目的〓〖HTK〗探讨应用连续切片EnvisionTM法检测角蛋白表达对判断头颈鳞状细胞癌淋巴结微转移的效果及微转移对肿瘤预后的影响。〖HTW〗方法〓〖HTK〗术中淋巴结标本行快速EnvisionTM法检测角蛋白CKAE1/AE3,与常规冰冻病理对淋巴结微转移检出率比较。对14例下咽癌、声门上型喉癌淋巴结标本连续病理切片,比较常规病理检测与EnvisionTM法对淋巴结微转移检出率。〖HTW〗结果〓〖HTK〗快速EnvisionTM法可检出2粒常规冰冻病理不能检出的淋巴结微转移,连续切片应用EnvisionTM法可检出5粒常规病理阴性的淋巴结(5/216)存在微转移灶。〖HTW〗结论〓〖HTK〗EnvisionTM法检测角蛋白CKAE1/AE3表达可快速判断头颈部鳞状细胞癌淋巴结微转移,存在多粒淋巴结微转移的患者预后可能较差。

Abstract:

Objective〓〖WTBZ〗To detect lymph node micro-metastasis and explore the clinical significance of lymph node micrometastasis in head and neck squamous cell carcinoma. 〖WTHZ〗Methods〓〖WTBZ〗25 lymph nodes taken from head and neck squamous cell carcinoma and frozen in the operations, and 223 lymph nodes taken form 14 cases of hypopharynx cancer or supraglottis cancer and serial sectioned were stained with the EnvisionTM system with monoclonal antibody CK(AE1/AE3) and H&E staining. The results were compared. 〖WTHZ〗Results〓〖WTBZ〗Two micro-metastasis lymph nodes which were not found by routine frozen section histological staining were found by the quick EnvisionTM system, and five micro-metastasis lymph nodes were detected from 216 H&E negative lymph nodes by using the immunohistochemisty EnvisionTM system. 〖WTHZ〗Conclusion〓〖WTBZ〗The EnvisionTM system is effective and reliable and can be used for intra-operative micro-metastasis examination. Patients with two or more micro-metastasis lymph nodes may have a poor prognosis.
