World's largest registry launches for deadly heart tumor
NCT ID NCT06715579
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This international registry will gather data from 500 people diagnosed with cardiac angiosarcoma, a rare and aggressive heart cancer. Researchers aim to identify risk factors and evaluate which treatments—like surgery, chemo, or immunotherapy—work best. The goal is to create evidence-based guidelines to improve survival and care for future patients.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this registry could help doctors identify better treatments and create standard care guidelines for this rare heart cancer.
- What could go wrong
- This is an observational registry, not a treatment trial. It collects existing data and won't directly test new therapies, so improvements may take years to emerge.

Inclusion Criteria: * Histological Confirmation: A confirmed diagnosis of cardiac angiosarcoma through histopathological examination, including subtypes such as hemangiosarcoma and epithelioid hemangiosarcoma. * Diagnosis Timing: Eligible patients must have been diagnosed between January 2015 and January 2035. * Geographical Representation: Participants should be from diverse geographical locations to ensure a comprehensive understanding of the disease across different populations. * Treatment Status: Patients who have received any treatment (surgery, chemotherapy, immunotherapy or radiation) for cardiac angiosarcoma may be included to evaluate treatment outcomes. * Informed Consent: For prospective patients, informed consent must be obtained before they are included in the registry. * Clinical Data Availability: Relevant clinical data, including demographics, tumor characteristics (size, location), treatment regimens, and outcomes, must be available for analysis. * Follow-Up Willingness: Participants should be willing to undergo follow-up assessments as part of the registry's data collection efforts. Exclusion Criteria: * Patients who decline to provide informed consent. * Cases where cardiac involvement is secondary to another primary malignancy
