Randomized Controlled Trial Comparative StudyPost-operative stereotactic radiosurgery versus observation for completely resected brain metastases: a single-centre, randomised, controlled, phase 3 trial.
After brain metastasis resection, whole brain radiotherapy decreases local recurrence, but might cause cognitive decline. We did this study to determine if stereotactic radiosurgery (SRS) to the surgical cavity improved time to local recurrence compared with that for surgical resection alone. ⋯ National Institutes of Health.

ReviewCardiotoxic effects of anthracycline-based therapy: what is the evidence and what are the potential harms?
Despite the known cardiotoxic effects of doxorubicin and other anthracyclines, no evidence-based guidelines exist for the surveillance and prevention of chemotherapy-induced cardiotoxicity in adult survivors of breast cancer who have had limited previous doses of anthracyclines (ie, total cumulative dose 240 mg/m(2)), or limited-dose anthracyclines followed by trastuzumab-based regimens. Nonetheless, some national and international cardio-oncology and cardiac-imaging organisations recommend increased cardiac surveillance during or after treatment, measurement of cardiac biomarkers and other surrogate endpoints, and in some cases initiation of cardioprotective drug therapy in asymptomatic women. ⋯ Whether existing cardio-oncology or imaging guideline recommendations will provide increased value or cause increased distress and lower health-related quality of life is unknown. Further research is needed to assess the long-term benefits, harms, and value of expanded cardiac surveillance, use of surrogate cardiac biomarkers, and prophylactic cardioprotective therapy in asymptomatic women with limited exposure to anthracyclines.

Although major advances have been reported in the last decade in the treatment of late-stage cancer with targeted and immune-based therapies, there is a crucial unmet need to develop new approaches to improve the prevention and early detection of cancer. Advances in genomics and computational biology offer unprecedented opportunities to understand the earliest molecular events associated with carcinogenesis, enabling novel strategies to intercept the development of invasive cancers. This Series paper will highlight emerging big data genomic approaches with the potential to accelerate advances in cancer prevention, screening, and early detection across various tumour types, and the challenges inherent in the development of these tools for clinical use. Through coordinated multicentre consortia, these genomic approaches are likely to transform the landscape of cancer interception in the coming years.

The world population is ageing and increasing in size. As a result, the numbers of people diagnosed with and dying of cancer are increasing. Cancer is also a growing problem in developing countries. ⋯ Through regulation, education, and support programmes, governments can create an environment in which tobacco use is reduced and citizens maintain good levels of physical activity, healthy bodyweight, and good nutrition. Cancer prevention and the creation of a culture of health is an essential mission of government, beyond that of the traditional health-focused departments such as health ministries; it is in the domain of governmental agencies involved in environmental protection, occupational safety, and transportation. Cancer prevention and health promotion are also in the realm of the zoning board, the board of education, and the board of health.
