摘要 目的研究P53和Ki-67在胃腺癌中表达阳性率,并探讨他们与临床病理指标的关系。方法收集2009年1月至2011年6月吉林大学第一医院经术后病理证实为胃腺癌的住院患者290例,全部病例均于我院病理科采用EliVision Plus免疫组织化学染色方法检测胃腺癌中P53和Ki-67的蛋白表达。结果 290例胃腺癌中P53和Ki-67蛋白表达的阳性表达率分别为46.9%(136/290)和78.6%(228/290)。P53和Ki-67蛋白阳性表达,在Lauren分型中,肠型显著高于弥漫型和混合型(均P<0.05);在Borrmannan分型中,0/Ⅰ/Ⅱ显著高于Ⅲ/Ⅳ(均P<0.05);高、中分化组显著高于低、未分化组(均P<0.05)。P53蛋白阳性表达,在贲门、胃底部显著高于胃体、胃窦、胃角部(均P<0.05);无远处转移组显著高于有远处转移组(均P<0.05)。Ki-67蛋白阳性表达,在T2~T4组显著高于Tis、T1组(均P<0.05);有淋巴结转移组显著高于无淋巴结转移组(均P<0.05)。非参数Spearman等级相关分析显示:P53和Ki-67呈正相关(r=0.292,P<0.05)。结论胃腺癌中P53及Ki-67的表达与临床病理指标有一定的相关性,联合检验可作为评估胃癌恶性程度及预后的参考指标。
