Dr. Julie Olin has highlighted an important issue for patients and providers contemplating systemic therapy for breast cancer: how the brain works after such treatment. Her excellent article summarizes four important studies, identifies the research design problems and questions raised by these and other studies, and proposes a model for how chemohormonal therapy might affect cognitive functioning and quality of life (see Figure 1 of her article). Finally, she identifies how actual, as well as potential, cognitive impairment might influence patient decisions and care (the author’s Table 1).
