摘要
目的 提高声门上型喉癌颈部转移淋巴结微小转移灶的检出率。方法 应用抗细胞角蛋白 (cytokeratin,CK ,AE1/AE3)单克隆抗体 ,LSAB免疫组化法对 46例 (50侧 )常规临床病理颈部淋巴结阴性 (pN0 )的颈深上淋巴结进行监测。结果 11例患者的 13枚淋巴结中发现微转移灶。结论 免疫组化法对微灶转移的检测比临床常规病理检查更敏感 ,因此是一临床更有使用价值的检查方法。
Objective Supraglottic carcinomas of larynx tends to metastasize to cervical lymph nodes The regular pathological method of diagnosis is easy to have the micrometastasis missed, and serial sectioning is too difficult be used in the regular pathological examinations The aim of this study was to evaluate the value of immunohistochemical assay in the detection of micrometastasis Methods Monoclonal antibodies against cytokeratin (AE1/AE3) were used to detect the cervical lymph nodes of 46 cases (50 sides of neck) of supraglottic carcinoma with pathologically negative findings (pN 0) Results Micrometastases were identified in 13 lymph nodes of 11 cases Conclusion It is suggested that the detection of lymph node micrometastases with immunohistochemical method is more sensitive than that of regular pathologic method It is comparable to serial sectioning Therefore, It is a valuable clinical method to detect the early lymph node metastasis
