Developing a cardiac monitoring plan in at-risk cancer survivors.

Abstract

133 Background: Improvements in early detection, screening, and treatment of cancer translate into survivors living longer, highlighting the need for guidelines to address the late and long-term effects of cancer treatment. A particularly concerning effect is Cancer Therapeutics-Related Cardiac Dysfunction (CTRCD). Cancer treatments can result in a range of cardiovascular toxicity including left ventricular dysfunction, heart failure and radiation-induced heart disease (RIHD). Various consensus statements related to cardiovascular care for adult cancer survivors exist; however there are no globally accepted follow-up guidelines. Our purpose is to create a protocol to stratify a survivor’s cardiac risk and provide a basis for follow-up recommendations. Methods: We first evaluated existing resources within our institution and identified key stakeholders who were recruited to form a multidisciplinary workgroup (2 survivorship advanced practice providers, an oncologist, a radiation oncologist, and 2 cardio-oncologists). We then reviewed current research and literature on cardiotoxic cancer therapies and identified two consensus statements from the American Society of Echocardiography and the European Association of Cardiovascular Imaging which helped inform our protocol. Finally, we created a cardiac assessment that could be applied in the pre-treatment phase and extend into the post-treatment phase. Results: Two assessment tools were developed. The first is an algorithm initiated in the pre-treatment setting by an oncologist when a Type I or Type II cardiotoxic agent is planned. The second is a risk assessment tool that is initiated in the post-treatment setting to stratify cardiac risk and provide follow-up recommendations. Conclusions: Development of standardized guidelines for assessment and treatment of late and long-term effects of treatment is critical. This protocol has been developed to account for the many factors that contribute to overall cardiac risk after various anti-cancer therapies. Further data is needed to evaluate long-term cardiac and survival outcomes based on this protocol.
