Primary cardiac angiosarcomas (PCA) are highly aggressive malignant heart tumors arising from the endothelial cells (ECs) lining the blood vessels of the heart and account for approximately 25%-30% of all primary cardiac malignancies. It is considered to be the most fatal and aggressive primary cardiac malignancy. This international registry aims to establish a large multicenter database of patients with cardiac angiosarcoma. Our objectives are: 1. Collect clinical data, including demographics, medical history, treatments, and outcomes, to build a comprehensive database. 2. Analyze data to evaluate and identify genetic, environmental, or lifestyle risk factors for cardiac angiosarcoma. 3. Evaluate the effectiveness of various treatments (surgery, chemotherapy, immunotherapy, radiation) to inform best practices. 4. Develop evidence-based guidelines and recommendations for prevention, diagnosis, treatment, and management based on registry data.

Primary cardiac angiosarcoma arises directly within the heart, unlike secondary cardiac tumors that originate from elsewhere in the body. While it predominantly affects the right side of the heart, particularly the right atrium, it can also impact other cardiac chambers and structures. The characteristic feature of cardiac angiosarcoma is the rapid formation of abnormal blood vessels that invade the myocardium, leading to the destruction of healthy heart tissue.The five-year survival rate for patients with primary cardiac angiosarcoma (PCA) is reported to be around 14%. In contrast, familial variants of this malignancy exhibit even more severe outcomes, with a mean survival rate of only 4 months. Establishing an international registry for cardiac angiosarcomas is crucial for several reasons: * The registry will facilitate a comprehensive understanding of the clinical characteristics, treatment responses, and outcomes associated with cardiac angiosarcoma. By collecting data from diverse populations, researchers can identify patterns and factors that influence survival rates. It is crucial to better understand the growth rates and risk factors associated with cardiac angiosarcoma and to make the disease more manageable. * The international registry will enable the latest advancements in oncology and related medical fields to be incorporated into clinical practice. It will provide a platform for developing and conducting clinical trials aimed at improving treatment strategies and increasing survival rates for patients with cardiac angiosarcoma. * Finally, with data from various institutions and countries, the registry will promote collaboration among healthcare professionals, researchers, and institutions dedicated to improving outcomes for patients with this rare malignancy. Creating an international registry for cardiac angiosarcoma is crucial for better understanding this aggressive cancer. It will help address the rising cancer burden and support research and treatment advancements that could improve patient survival rates and prevention. The following data will be collected through questionnaires: 1. Patient characteristics 2. Characteristics of Primary Cardiac Angiosarcomas 3. Details of the diagnosis and treatment 4. Complications and late effects of treatment 5. Outcomes and follow-up information Quality control and data management will be done by the Immune Oncology Research Institute.
