摘要 目的检测乳腺癌组织中HER-2蛋白与基因扩增的一致性,探讨其对乳腺癌发展及预后的临床意义。方法应用免疫组织化学法和FISH法检测乳腺癌组织(n=142)中HER-2蛋白表达和基因扩增情况,并对142名患者进行随访调查。结果免疫组织化学显示HER-2蛋白+、、的百分率分别为12.7%(18/142)、26.8%(38/142)、22.5%(32/142),蛋白+、、的病例中基因扩增比率分别为22.2%(4/18)、31.6%(12/38)、68.8%(22/32),二者差异有统计学意义(P<0.000 1);HER-2蛋白表达及基因扩增与临床病理相关因素(年龄、绝经与否、病理分级、临床分期)无关(P>0.05),与肿瘤大小及淋巴结转移有关(P<0.05);HER-2蛋白表达阳性及基因扩增阳性患者生存曲线低于阴性患者(P<0.05),HER-2阳性表达及淋巴结转移是影响患者无瘤生存时间的危险因素(P<0.001)。结论乳腺癌中免疫组织化学检测HER-2蛋白表达是临床使用赫赛汀的"初筛",与FISH法联合检测才能较为准确的指导临床用药;HER-2对乳腺癌的发展和预后有重要的作用,HER-2和淋巴结转移可做判断患者预后的重要指标。
