One-in-a-million people are living with EHE worldwide.

Our mission is to find treatments and a cure for epithelioid hemangioendothelioma (EHE) by advancing research and driving collaboration among patients, researchers, and clinicians.

We envision a world where Epithelioid Hemangioendothelioma (EHE) is easily diagnosed and treatable. Join our dedicated community by subscribing to our emails.

Patient-Powered EHE Research

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.

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.

Understanding Quality of Life for People Living With EHE

By Kristianne Oristian, PhD | February 10, 2026

The European Organisation of Research and Treatment of Cancer (EORTC) is conducting research to better understand health-related quality of life (HRQoL) concerns among people living with rare cancers. Recently, researchers analyzed results from a group of 31 people with EHE from 11 different countries who participated in the study. The findings showed that pain–and the […]

Exploring Eribulin as a Potential Treatment Option for EHE

By Kristianne Oristian, PhD | February 10, 2026

Prior research has shown that a class of medications called microtubule inhibitors may be effective at controlling the growth of EHE tumors. Recently, researchers conducted a phase 2 study to test whether the microtubule inhibitor eribulin is a safe and effective way to treat patients whose tumors continued to grow after prior treatment. Six (6) […]

Reflecting on 2025 and Looking Ahead With Purpose

By EHE Foundation | January 20, 2026

For the global EHE community, 2025 brought challenges, resilience, and momentum. Grounded in connection and a shared commitment to progress in EHE, we look back with emotion, appreciation, and gratitude, and in 2026, we look forward with determination and hope.

Translating molecular mechanisms of EHE to improve patient outcomes

By Kristianne Oristian, PhD | December 17, 2025

Scientists know that most EHE tumors are caused by specific genetic changes called gene fusions. In most people with EHE, two genes, WWTR1 and CAMTA1, are abnormally fused. In a smaller number of cases, a different fusion involving YAP1 and TFE3 is present. In a recent review published in Critical Reviews in Oncology/Hematology, the authors […]

EHE Stabilization with Sirolimus: Results From POEM, a Prospective Multicentric Observational Study

By EHE Foundation | November 6, 2025

Drs. Claudia Giani, Anna Maria Frezza, Silvia Stacchiotti, and colleagues from the Fondazione IRCCS Istituto Nazionale dei Tumori, Milan, Italy, and Royal Marsden Hospital, London, UK, presented results from POEM: a prospective observational study on Epithelioid Haemangioendothelioma at ESMO Congress 2025. The data presented included 57 consecutive molecularly confirmed EHE patients who entered the study, […]

Hanna Lab at Purdue University: ‘When cells in the body stop following the rules, cancer can take hold.’

By EHE Foundation | October 14, 2025

You met Jason Hanna, PhD, at the 2025 EHE Global Patient Conference, where he highlighted work his lab is undertaking in EHE. We are thrilled to share a recent publication in Molecular Oncology from the Hanna Lab at Purdue University, highlighting their findings from a study focused on the YAP1-TFE3 subtype of EHE.  The YAP1-TFE3 […]
