Researchers have identified a genetic signature that can predict which breast cancer patients will respond well to treatment with epirubicin, a widely used form of chemotherapy. Although among the most effective chemotherapies in breast cancer, a small proportion of women suffer severe side-effects.

By identifying those women who are most likely to benefit from treatment, doctors may be able to ensure fewer women are unnecessarily exposed to that risk. The new study shows that this goal can be achieved by developing more sophisticated ways to use older drugs.
