Abstract 11675: Global Cardio Oncology Registry: Structure for a Multinational Collaboration

Abstract

Introduction: Global collaboration in cardio-oncology (CO) is needed to understand the prevalence of cancer treatment related cardiovascular disease (CTRCD) in different risk groups, practice settings and geographic locations. Furthermore, socio-economic and ethnic disparities may impact access to care. Methods: We assembled cardiologists (CA) and oncologists from academic and community settings to collaborate in the first global cardio-oncology registry (G-COR). US and international CO physicians participated in the first global virtual meeting to assess feasibility and structure for G-COR. Subsequently, a survey for sites resources, demographics and intention to participate was conducted. Results: Responses with sites demographics from 104/140 sites invited: 43 US sites from 23 states and 61 international sites from 5 continents indicated decision to participate in G-COR. Sites were more commonly led by CA (74/99) than CA and oncologists (25/99) and were more often University/teaching (68/101) than community based (33/101). Significant minorities/disadvantaged CO patient population were reported by 32/43 US sites versus 16/60 international sites. Average number CO patients treated per month was 83, range (5-1,000). Breast cancer was the first or second G-COR priority for 84 centers, hematological malignancies (HEM) for 66 centers, and immune check point inhibitors (ICI) for 36 centers. Echocardiography with strain imaging is available in 92/95 participating sites and cardiac MRI in 80/86 sites. Biomarkers are used only in suspected or confirmed CTRCD in 56/96 sites and for risk stratification in high risk patients in 40/96 sites. Subsequently, scientific committee and topic committees for breast cancer, HEM, ICI, and disparities in CO were established. A pilot phase utilizing a RedCap Cloud platform will start enrolling patients in the last quarter of 2021 and the registry for all main pillars will launch in early 2022. Conclusions: We present a global initiative for conducting collaborative research. Information learned G-COR will help understanding risk factors impacting CTRCD in different geographic locations and therefore help reducing access gaps in CO care. Additionally, mitigating strategies can be devised for the future.
