摘要 目的研究肿瘤坏死因子相关凋亡诱导配体(TNF-related apoptosis-inducing ligand,TRAIL)在低位直肠癌癌旁组织新辅助放化疗前后的表达情况。方法选取2011年6月至2013年10月低位直肠癌患者60例,分别于放化疗前活检及放化疗手术后取材癌旁组织,利用免疫组织化学SP法分别检测放化疗前后TRAIL的表达情况。结果新辅助放化疗后TRAIL在癌旁组织的阳性表达率较放化疗前升高40%,差异有统计学意义(P<0.05)。结论 TRAIL的表达情况与肿瘤的分期密切相关(经放化疗后肿瘤降期),提示通过检测患者癌旁组织的TRAIL的表达,或有助于判断肿瘤患者的预后。
