Synthetic lethality has emerged as a novel approach to treat cancer. Inhibitors of poly (ADP-ribose) polymerase, a target that has synthetic lethality withBRCAmutations, have already shown promise in clinical trials. The authors of this Review describe the clinical application of synthetic lethality for patients with breast cancer, and discuss biomarkers that can be used to select patients who will respond to this therapy. Other potential genes that could be involved in synthetic lethality, and are thus new targets, are also explored.
