摘要 目的探讨胃癌发生和演进中Beclin1基因的表达水平及其与临床特征的关系。方法胃癌、癌旁黏膜和转移淋巴结石蜡或新鲜标本各30例进行免疫组织化学检测。结果 Beclin1蛋白在胃癌组织中的表达定位于细胞质,在胃癌组、胃癌前病变和对照组中的表达强度逐渐增强,在对照组中绝大多数为强阳性表达。三组灰度值差异显著(P<0.05);组间两两比较,差异均显著(P<0.05)。Beclin1的表达强度与淋巴结转移及胃癌分化程度密切相关(P<0.05),与肿瘤的部位、大小、浸润深度和TNM分期无明显相关性(P>0.05)。结论 Beclin1蛋白表达改变对胃癌的分化及转移影响较大。早期检测Beclin1蛋白的表达水平对胃癌的早期诊断及预后评估意义重大。
