Patient-Powered EHE Research

EHE Global Patient Registry

The EHE Global Patient Registry empowers people with Epithelioid Hemangioendothelioma (EHE) to join together to improve our understanding of this ultra-rare sarcoma. We need every EHE patient to join this critical tool used to support researchers searching for treatments and a cure for EHE.

EHE Biobank

Patients are the key to finding new treatments for EHE! Researchers need tumor tissue and fluid from EHE patients to understand disease progression and speed the development of new drugs and therapies.
