1、胃癌组织中P16,CMYC和COX2的表达及其与患者预后的关系作者:翟俊山李楠张林王艳梅朱超慧吴凯【摘要】目的]探讨胃癌组织中P16,CMYC和COX2表达情况、相互关系及其与患者预后的关系。[方法]应用免疫组化SABC法检测104例手术切除胃癌组织中P16,CMYC和COX2的表达。[结果]胃癌中P16,CMYC和COX2表达阳性率分别39.4%(41/104),57.7%(60/104),63.5%(66/104)。P16的表达在胃癌中与不同的浸润深度,淋巴结有无转移,TNM分
2、期,不同组织学类型均有显著差异(P<0.05);CMYC的表达在胃癌中与不同的浸润深度,淋巴结有无转移,TNM分期有显著差异(P<0.05),而与不同组织学类型无统计学差别(P>0.05);COX2的表达在胃癌中与淋巴结有无转移,TNM分期,不同组织学类型均有显著差异(P<0.05),而与不同的浸润深度无统计学差别(P>0.05)。而它们与肿瘤患者年龄,性别均无统计学差异(P>0.05)。等级相关分析结果显示P16与CMYC、COX2表达呈负相关(P<0.05),CMYC与COX2表达
3、呈正相关(P<0.05)。生存曲线研究结果显示P16,CMYC和COX2表达与患者术后生存时间显著相关(P<0.05)。[结论]P16在胃癌组织中低表达及CMYC和COX2高表达能客观反映胃癌组织分化程度,侵袭转移能力,且其与患者预后密切相关。故检测三种指标可正确判断胃癌患者预后,在指导临床治疗方面有一定价值。【关键词】P16;CMYC;COX2;胃癌;预后;基因表达 Abstract:[Objective]ToinvestigatetheexpressionofP16,CMYCa
