摘要 目的探讨老年乳腺癌O6-甲基鸟嘌呤-ONA-甲基转移酶(MGMT)、谷胱甘胱-S-转移酶(GST-π)、缺氧诱导因子-1(HIF-1α)表达与临床预后之间的关系。方法应用组织芯片技术和免疫组织化学方法检测老年乳腺癌34例MGMT、GST-π、HIF-1α的表达,并与临床预后资料进行分析。结果MGMT、GST-π、HIF-1α的阳性表达率分别为47%(16/34)、58%(19/34)、64%(22/34);MGMT阳性表达与组织学类型、TNM分期密切相关(P<0.05),与肿瘤体积、淋巴结转移无关(P>0.05);GST-π阳性表达与TNM分期、淋巴结转移密切相关,与组织学类型、肿瘤体积无关(P>0.05);HIF-1α阳性表达与组织学类型、肿瘤体积密切相关,与TNM分期、淋巴结转移无关(P>0.05)。经多因素cox比例风险模型分析显示:TNM分期、肿瘤组织类型及MGMT、HIF-1α阳性表达与乳腺癌患者术后生存率有关(P<0.05)。结论TNM分期、肿瘤组织类型及MGMT、HIF-1α可作为老年乳腺癌的独立预后指标。
