Cardio-Oncology Considerations for Breast Cancer: Risk Stratification, Monitoring, and Treatment
Abstract:
Long-term outcomes of patients with breast cancer have steadily improved due to advances in early detection and cancer therapeutics. Cardiovascular disease (CVD) is a leading cause of non-cancer-related mortality in this population, and this has been attributed to the cardiovascular toxicity of common breast cancer treatments including chemotherapy and radiation as well as shared risk factors between cancer and CVD. Identifying patients at risk of developing treatment-related cardiotoxicities is crucial to inform clinical decisions regarding surveillance, prevention, and management. In this review, we provide a broad overview of the treatment-related cardiotoxicities associated with common breast cancer treatment. We present data on risk-stratification tools for oncologists, including when to refer to a cardiologist, as well as recommendations for cardiovascular testing tailored to individual treatment regimens. Lastly, we review recent trial data on preventive and therapeutic approaches to treatment-related cardiotoxicities, and future directions that may lead to improved cardiovascular outcomes in this population.

Cancer Therapies
However, cancer treatments can pose several challenges, as therapies used to kill cancer cells are generally also toxic to normal cells. Moreover, cancer cells mutate rapidly and can develop resistance to chemical agents or radiation therapy. Besides, all types of cancer cells may not respond to the same therapy. Some cancer cells respond to one...
