摘要 为探讨XIAP和bcl-2在乳腺癌中的表达及其与细胞凋亡和增殖的关系,笔者采用免疫组化SP法检测60例乳腺癌中的XIAP,bcl-2和增殖细胞核抗原(PCNA)的表达,并用TUNEL法测定凋亡指数。结果示XIAP在患者的年龄、肿瘤大小、组织学分级、淋巴结转移等指标各组间差异无显著性(均P>0.05),但患者的生存期≥3年者XIAP的表达率显低于<3年者(P<0.05)。bcl-2在乳腺癌I级,II级与III级相比较差异有显著性(P<0.05)。XIAP与细胞凋亡和增殖有关;而bcl-2仅与细胞凋亡有关。提示XIAP与乳腺癌患者的生存期有关,可作为独立的评估预后的因素;其表达与bcl-2表达之间无关,提示两者是通过不同途径发挥各自的生物学作用。
