Scientists launch international registry to crack the code of ultra-rare cancer EHE
NCT ID NCT06408441
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study creates a registry to collect information from 100 adults newly diagnosed with epithelioid hemangioendothelioma (EHE), an ultra-rare sarcoma. Researchers will track patients over time to understand how the disease progresses, what factors affect outcomes, and which treatments are used. The goal is to improve knowledge and care for this rare cancer.
