摘要(Abstract):
目的:探讨多药耐药相关蛋白(MRP)基因表达与原发上皮性卵巢癌(PEOC)耐药的关系及其临床意义。方法:应用半定量RT-PCR技术,检测37份PEOC,10份正常卵巢上皮组织和20份正常女性外周血单个核细胞(PBMC)新鲜标本MRP基因的表达,用MTT法检测PEOC患者的原代癌细胞对临床常用抗癌药物的敏感性。结果:(1)PEOCMRP基因表达水平明显高于正常卵巢上皮组织(P<0.05),与PBMC差异无显著性(P>0.05);(2)MRP基因表达与PEOC临床期别及组织学类型无关,但随组织学级别升高而升高(P<0.05);(3)MRP基因高表达组MMC、ADM、E-ADM、VCR、VP16和CDDP对PEOC细胞抑制率与低表达组差异有显著性,余则无显著性;(4)MRP和MDR1基因表达里正相关(r=0.213,P<0.01),且与无进展生存期有关,而与总体生存期无关。结论:MRP基因表达与PEOC耐药有关,是抗MDR相关药物的重要原因之一。MRP基因表达的检测对临床用药有指导意义,对临床疗效判断和患者预后预测有一定价值。
