摘要 目的研究MUC2蛋白在人类胃组织中的表达与临床病理特征及预后的关系。方法采用免疫组化S-P法检测55例胃癌组织、15例正常胃粘膜及25例肠化生粘膜中MUC2蛋白表达情况。结果正常胃粘膜中无MUC2蛋白表达,MUC2蛋白在肠化生粘膜及胃癌组织中的表达率分别为36.0%和61.8%,差异有统计学意义(P<0.05)。胃癌组织中MUC2的表达与患者年龄、性别、肿瘤部位、肿瘤大小、大体类型、浸润深度无关(P>0.05),而与病理组织学类型及淋巴结转移有关,粘液腺癌较高、低分化腺癌高表达(100%vs54.5%vs50.0%),有淋巴结转移较无淋巴结转移高表达(73.5%vs42.9%),差异有统计学意义(P<0.05)。已死亡患者较尚生存患者胃癌组织MUC2蛋白高表达(80.9%vs52.9%),差异有统计学意义(P<0.05)。结论 MUC2蛋白在粘液腺癌及伴淋巴结转移胃癌组织中表达较高,MUC2蛋白阳性患者较阴性患者预后不佳。
