研究表明,ｕＰＡ介导的纤维蛋白降解作用与恶性肿瘤的侵袭和转移密切相关〔1〕。临床上许多乳腺癌患者都死于肿瘤的复发和转移。然而,ｕＰＡ在乳腺癌中的表达与淋巴结转移及预后的关系,国内至今未见报道。本研究将通过免疫组化ＳＡＢＣ法观察ｕＰＡ与乳腺癌淋巴结转移的关系,并
Studies have shown that uPA-mediated fibrin degradation and invasion and metastasis of malignant tumors are closely related (1). Many clinical breast cancer patients die of tumor recurrence and metastasis. However, the relationship between uPA expression in breast cancer and lymph node metastasis and prognosis has not been reported in China so far. This study will observe the relationship between uPA and lymph node metastasis of breast cancer by immunohistochemical SABC method and
