  • 摘要:   目的  检测乳腺浸润性微乳头状癌(invasive micropapillary carcinoma,IMPC)中乙醛脱氢酶2(acetaldehyde dehydrogenase 2,ALDH2)的表达,探讨ALDH2表达水平对IMPC患者新辅助化疗方案的指导意义。  方法  选取2009年1月至2014年5月298例于天津医科大学肿瘤医院行新辅助化疗(neoadjuvant chemotherapy,NAC)的乳腺癌患者的临床病理资料,其中IMPC为84例、浸润性导管癌非特殊型(invasive ductal carcinoma no special type,IDC-NOS)为214例。采用倾向评分匹配法成功匹配84例IMPC与IDC-NOS,检测ALDH2在IMPC组和IDC-NOS组中的表达差异,分析IMPC患者中ALDH2不同表达组的临床病理特征、NAC反应分级与预后相关性。  结果  ALDH2在IMPC中的表达水平为48.8%(41/84),显著高于IDC-NOS的33.3%(28/84),两者比较差异具有统计学意义(P=0.041);IMPC患者中ALDH2表达水平与N分期(rs=0.348,P=0.017)及p53突变水平(rs=0.262,P=0.016)呈正相关,与NAC反应分级及无病生存率(disease-free survival,DFS)呈负相关(均P<0.05)。  结论  在IMPC中ALDH2高表达且与NAC反应分级及DFS呈负相关。针对ALDH2高表达的IMPC患者应尽早行手术切除,以延长生存预后。
