摘要 目的:探讨耐药基因组合检测的临床应用问题和表达结果与药物间在个体化化疗中的适配分析。方法:90例恶性肿瘤病例,应用免疫组化染色检测耐药基因TS、GST-Pi、TOPOⅡ和Ki-67的表达结果用以指导临床化疗;以定性结果与不同的半定量表达法结合指导选药作适配分析。结果:总的阳性表达率TS48%,GST-Pi69%,Ki-67和TOPOⅡ均为99%,而同一耐药基因表达产物在不同类型肿瘤组织中的阳性表达率,TS为41%~100%,GST-Pi为24%~91%;在阳性半定量中,TS为10%~60%,GST-Pi和TOPOⅡ均为10%~80%,Ki-67为10%~90%。三组适配分析方案中,以定性结果指导选药,两类以上药物适配的病例只有66%;而以定性结合分级定量结果指导选药可达到80%;再以定性联合百分比定量结果指导选药则上升到99%。结论:TS、GST-Pi、TOPOⅡ和Ki-67组合检测,基本上满足各类恶性肿瘤耐药基因的检测需要;定性联合百分比定量结果指导选药能够达到"个体化"的最佳适配。
