摘要
收集石腊包埋组织标本膀胱癌80例、肺癌69例、大肠癌37例,对有转移者同时收集其转移灶标本,应用免疫组织化学法检测NDPK/nm23-H1的表达情况。结果显示:NDPK/nm23-H1在膀胱癌、肺癌和大肠癌中表达的阳性率分别为64%、80%和94%;其表达水平在膀胱癌、大肠癌与分化程度有关,随分化程度降低而显著降低(P<005);在肺癌与组织学类型有关,以肺鳞癌中最高,其次为腺癌和小细胞癌(P<005);在大肠癌与淋巴结转移有关,伴淋巴结转移者其原发灶中显著降低(P<001);对原发灶和转移灶的配对分析,未发现相关性。提示NDPK/nm23-H1表达水平是一个与肿瘤恶性行为相关的因素,但其临床意义存在组织学差异。
To elucidate its clinical significance in human cancer tissues,the expression of NDPK/nm23-H 1 was detected by immunohistochemical technique.Results:In cancer tissues of bladder、lung and large intestine,the positive staining rates were 64%(51/80)、80%(55/69) and 94%(35/37) respectively;Both in bladder and in large intestine tissues,the immunoreactivity of NDPK/nm23-H 1 was possitively correlated with the cancer cell differentiation ( P <0 05);Moreover in lung cancer tissues,there was relationship between the immunoreactivity and the cell types,it was higher in squamous cell carcinoma than that in adenocarcinoma and small cell carcinoma;In addition in Large intestine cancer tissues,the immunoreactivity was negatively related with the metastasis pertential of lymph nodes ( P <0 05).These results suggest that the immunoreactivity of NDPK/nm23-H 1 was indeed related to the malignancy of tumor,but its clinical significance was varied in different tissues.
