Is this trial a fit for you?

Likely a good fit

Ideal candidates are adult patients aged 18 years and older with a newly diagnosed, pathologically confirmed case of EHE.

Probably not a fit

Patients with a diagnosis of EHE prior to December 1, 2023, or those without molecular confirmation of the diagnosis will not benefit from this study.

What this trial studies

This registry collects high-quality prospective data on patients diagnosed with epithelioid hemangioendothelioma (EHE), an ultra-rare sarcoma. The study aims to improve understanding of the disease's natural history, identify prognostic factors, and evaluate treatment patterns and efficacy. It includes only new cases confirmed by expert pathologists and focuses on gathering comprehensive clinical data to address existing knowledge gaps. The registry is part of the European Reference Network on Rare Adult Solid Cancers (EURACAN).

Why it matters

Potential benefit: If successful, this registry could lead to improved management and treatment strategies for patients with epithelioid hemangioendothelioma.

How similar studies have gone: While this registry approach is novel for EHE, similar registries for rare cancers have shown success in improving understanding and treatment outcomes.
