聚ADP-核糖聚合酶(Poly ADP-ribose polymerase,PARP)抑制剂(PARPi)是一组靶向携带BRCA1/2或其他同源重组因子有害突变的乳腺癌与卵巢癌的新型抗癌药物。PARPi的临床应用已取得显著成果,是近年来临床肿瘤学的重大突破之一。然而,PARPi耐药正在成为一个严重的临床问题。研究和了解PARPi耐药机理对克服肿瘤耐药和提高疗效具有重要意义。最近的研究进展已经揭示了一些诱发PARPi耐药的机制,包括上调多药耐药基因,改变PARylation酶,重建同源重组修复和恢复复制叉稳定性。本文将综述这些变化如何导致癌细胞对PARPi产生耐药并讨论克服PARPi耐药的可能策略。
