应用亲合组织化学方法对９２例原发性肺鳞癌西非单叶豆（ＢＳＬ）受体的表达进行了临床病理学研究。结果发现，ＢＳＬ受体在肺鳞癌中的质膜阳性率高于胞浆阳性率（Ｐ＜０．０５）。质膜阳性率在鳞癌的不同组织学分级之间差异有显著性（Ｐ＜０．０５），随鳞癌分级的增加，质膜阳性率降低。ＢＳＬ受体全细胞阴性表达率在有、无肺门淋巴结转移两组间差异有显著性（Ｐ＜０．０５），ＢＳＬ受体质膜阳性率及细胞全阴性率在生存期不同病人间差异有显著性（Ｐ＜０．０５，Ｐ＜０．０２５）。提示ＢＳＬ受体对肺鳞癌有相对特异性，与肺鳞癌临床病理的生物学行为有一定的关系。
A clinicopathological study was performed on 92 cases of primary lung squamous cell carcinoma (BLR) recipients using affinity histochemistry. The results showed that the positive rate of plasma membrane of BSL receptor in lung squamous cell carcinoma was higher than that of cytoplasm (P<0.05). The positive rate of plasma membrane was significantly different between different histological grades of squamous cell carcinoma (P<0.05). With the increase of grading of squamous cell carcinoma, the positive rate of plasma membrane was decreased. The negative rate of whole cell BSL receptor expression was significantly different between the two groups with and without hilar lymph node metastasis (P<0.05). The positive rate of plasma membrane and total cell negativity of BSL receptor were different among patients with different survival stages. Significant (P<0.05, P<0.025). It suggests that BSL receptor is relatively specific to squamous cell carcinoma of the lung and has a certain relationship with the biological behavior of lung squamous cell carcinoma.
