摘要 目的探讨多药耐药(multi-drug resistance,MDR)基因产物P-糖蛋白(P-gp)、胎盘型谷胱甘肽转移酶(GST-π)、胸苷酸合成酶(TS)及DNA拓扑异构酶Ⅱ(TopoⅡ)与胃癌的组织学类型、生物学行为、临床病理及预后等的关系,为胃癌化疗治疗中化疗药物的选择提供依据。方法免疫组化SP法检测胃癌组织中P-gp、GST-π、TS和TopoⅡ的表达。结果 65例胃癌手术标本中,P-gp阳性52例(80%);TopoⅡ阳性52例(80%);TS阳性56例(86.15%);GST-π阳性44例(67.69%)。P-gp的表达与胃癌病变直径和有无淋巴结转移有关;TopoⅡ的表达与胃癌分化程度有关,GST-π的表达与胃癌病变大小有关;TS的表达与胃癌临床病理参数均无关系。结论 P-gp、GST-π、TopoⅡ指标除做化疗的指标外,也是临床判断胃癌分期及细胞分化的指标。
