胆管癌的生长以浸润性生长为特征 ,其浸润和转移导致手术切除范围不能达到根治的目的 ,是术后复发的主要原因。我们运用免疫组化法对 5 6例胆管癌石蜡切片进行研究 ,探讨Ｅ ｃａｄｈｅｒｉｎ (Ｅ ｃａｄ)与胆管癌浸润和转移的关系。材料和方法1.对象 :1990～ 1998年间经手术切?
The growth of cholangiocarcinoma is characterized by infiltrative growth. The infiltration and metastasis of cholangiocarcinoma can not reach the goal of radical resection, which is the main reason of postoperative recurrence. We used immunohistochemical staining of 56 paraffin-embedded sections of cholangiocarcinoma to investigate the relationship between E cadherin (E cad) and infiltration and metastasis of cholangiocarcinoma.
