Poly(ADP-ribose) polymerase (PARP) inhibitors are approved for patients with several forms of cancer, predominantly those harbouring loss-of-function BRCA1/2 mutations or other homologous recombination defects. Nonetheless, most patients receiving PARP inhibitors will ultimately develop resistance to PARP inhibitors, resulting in disease progression. In this Review, the authors describe the mechanisms of resistance to PARP inhibitors and discuss the potential treatment strategies that might overcome these effects.
