摘要: 目的探讨乳腺癌特异基因(BCSG1)在乳腺癌新辅助化疗疗效评估中的价值。方法采用免疫组化SP法和荧光定量PCR方法检测36例乳腺癌患者新辅助化疗(CEF方案)前后乳腺癌组织BCSG1的表达情况,比较化疗前后肿瘤体积的变化情况,分析新辅助化疗前后BCSG1蛋白表达与肿瘤形态学变化的关系。结果 36例乳腺癌患者新辅助化疗后肿瘤体积均有明显缩小(P<),病灶缓解率(CR+PR)%;新辅助化疗后BCSG1 mRNA表达水平亦明显低于化疗前(P<),BCSG1蛋白高表达率低于新辅助化疗前(P<)。结论乳腺癌新辅助化疗后BCSG1在分子和蛋白水平均明显降低,与新辅助化疗后肿瘤缩小呈正相关,提示BCSG1可作为乳腺癌新辅助化疗疗效的预测因子。

Abstract:Objective To discuss the importance of BCSG1 on evaluating the curative effect of neoadjuvant chemotherapy to breast cancer. Methods The expressions of BCSG1 of cancer was assayed by immunohistochemistry and RT-PCR in 36 cases of breast cancer patients before and after receiving neoadjuvant chemotherapy of CEF (Cyclophosphamide, Epirubicin and Fluorouracil) regimen. The therapeutic response of neoadjuvant chemotherapy was evaluated by the morphological and pathological observation. The relationship between expressions of BCSG1 and morphological response to neoadjuvant chemotherapy was analyzed. Res
