摘要 目的探讨胃小细胞癌组织中PTEN、p73基因蛋白表达与临床预后的关系。方法采用免疫组化S-P法检测58例胃小细胞癌患者癌组织中PTEN和p73基因蛋白的含量,并对58例病人进行术后随访。结果PTEN在局部淋巴结转移组的低表达率明显高于局部淋巴结无转移组(P<0.01),且随着组织学分级的增高,浸润深度的加深,其低表达率逐渐增高(P<0.01),PTEN低表达组的生存时间明显低于高表达组。p73在局部淋巴结转移组的高表达率明显高于无淋巴结转移组(P<0.05);随着组织分级的增高,浸润深度的加深,其表达率增高。p73低表达组的生存时间明显高于高表达组。结论PTEN基因的低表达、p73基因的高表达与胃小细胞癌的发生发展和临床预后存在一定的关系。
