Abstract： 目的:研究CD44v6在胃癌胃镜标本和术后标本中的表达,并分析其与胃癌生物学行为的关系.方法:随机选取辽宁医学院附属第二医院普通外科2004-2009年收治的有详细病例资料的胃癌患者50例,应用免疫组织化学方法检测胃镜标本和术后标本胃组织中CD44v6的表达.结果:CD44v6在胃癌胃镜标本、术后标本和转移淋巴结中的表达率分别为60.00%、64.00%、80.77%.显著高于胃良性病变(P＜0.01);CD44v6在肠型胃癌中的表达率显著高于弥漫型胃癌(75.86% vs 47.62%,P＜0.05).胃癌胃镜和术后标本中CD44v6的表达与胃癌浸润深度,TNM分期和淋巴结转移均有关(P＜0.05).CD44v6在胃癌胃镜标本和术后标本中的总体表达率无显著性差异(P＞0.05);相同临床病理参数,CD44v6在胃癌胃镜标本和术后标本中的表达率无显著性差异(P＞0.05).结论:CD44v6可作为术前预测胃癌的发生、病期进展和转移潜能的辅助生物学指标之一.
