Abstract:

【】 目的 探讨葡萄糖转运蛋白Ⅰ型(glucosetransporter1,GLUT1)和肿瘤增殖细胞核抗原Ki-67在卵巢上皮性肿瘤组织中的表达及其临床意义。 方法 收集2000年1月-2008年6月不同卵巢上皮性肿瘤病变患者119例的组织标本,采用免疫组织化学SP二步法检测肿瘤组织中GLUT1和Ki-67的表达情况。 结果 卵巢交界性、恶性上皮性肿瘤灶性或广泛高表达GLUT1和Ki-67,其表达强度有差异。卵巢良性上皮性肿瘤不表达GLUT1和Ki-67。在卵巢癌中GLUT1及Ki-67的表达强度与病理分级、临床分期、预后有关。GLUT1表达强度与病理分型无关,Ki-67表达强度与病理分型有关。 结论 卵巢上皮性肿瘤组织中GLUT1和Ki-67的表达具有相关性,其表达强度与肿瘤的良恶性质和增殖状态有关,二者同时检测可以全面了解卵巢上皮性肿瘤的性质、卵巢癌恶性程度和生物学行为,对于判断肿瘤的性质和预后有一定价值。?【Abstract】 Objective Toinvestigatetheexpressionandclinicalsignificanceofglucosetransporter-1(GLUT1)andtumorproliferatingkaryonantigenKi-67inepithelialovariantumortissue.
