摘要
目的研究nm23基因产物与肺癌临床病理间的关系。方法应用SABC免疫组化法,检测69例肺癌中nm23基因产物二磷酸核苷激酶(NDPK)的表达情况。结果nm23在肺癌中有较高表达,阳性率79.7%(55/69),其中鳞癌100%(31/31),腺癌71.4%(20/28),小细胞癌40%(4/10),在鳞癌中的表达较腺癌及小细胞癌高(p<0.05)。但nm23的表达与肺鳞癌的分化程度无关(p>0.05),与肺鳞癌、肺腺癌及其它肺癌有无肺门或纵隔淋巴结转移无关(p>0.05)。结论提示肺癌的形成和转移与多基因、多步骤的遗传学改变有关,应将nm23基因与其他因素进行同时研究,以准确反映肺癌恶性生物学行为的重要特点。
Objective Expression of nucleoside diphosphate kinase(NDPK),a product of metastasis suppresor gene nm23,was detected in 69 cases of lung carcinoma.Methods Immunohistochemical technique was used.Results The total positive rate was 79.7%.But the nm23 protein expression has not retated to the histological grade of the squamous cell tumors of the lung and metastasis of the cancer of the lung(p<005).Conclusion Whether nm23 serves as a valuable marker in carcinoma of the lung need to be researched in further.
