层粘连蛋白及其受体在妊娠滋养细胞肿瘤中的表达及意义

目的　了解葡萄胎、侵蚀性葡萄胎和绒毛膜癌组织中层粘连蛋白(L N )及其受体(L N - R)的表达,并探讨L N、L N - R与妊娠滋养细胞肿瘤(GTT)侵袭和转移的关系。方法　以4 4例恶性GTT为研究组,2 4例葡萄胎为对照组,采用免疫组化方法对两组患者首次清宫标本组织进行L N,L N- R检测。结果　L N在绒毛膜癌组织中临床分期越晚,表达率越高,其表达与绒毛膜癌细胞的浸润转移以及恶性程度有一定关系。结论　化疗对L N、L N- R在妊娠滋养细胞肿瘤中的表达有一定的影响,推测L N和L N- R在妊娠滋养细胞肿瘤抗侵袭和转移治疗方面具有潜在的应用价值。

Expression of Laminin and Laminin Receptor in Gestational Trophoblastic Tumor and Its Significance

Objective This study was conducted to detect the expression of laminin (LN) and laminin receptor (LN-R) in the specimens of hydatidiform mole (HM), invasive mole (IM) and choriocarcinoma(CC), respectively. Methods The immunohistological staining method was used. Results It was found that the level of laminin expression was higher in the specimens of choriocarcinoma at more advanced stage. Conclusion The results suggest that there may be relations between the invasion and metastasis of choriocacinoma cell and the malignant degree of this disease, chemotherapy has some effect on the expression of LN and LN-R in gestational trophablastic tumor(GTT), and that LN and LN-R may be of potential value in GTT treatment. However, referring whether LN and LN-R could be used as clinical prognos ticators, further studies will be needed.
