Epithelioid sarcoma (ES) is a rare tumor hallmarked by the loss of INI1/SMARCB1 expression. Apart from this alteration, little is known about the biology of ES. Despite recent advances in treatment, the prognosis of ES remains unsatisfactory.

Stress-induced analgesia (SIA) refers to the reduction in pain sensitivity that can occur in response to acute stress. On the contrary, chronic stress exposure may lead to a phenomenon named stress-induced hyperalgesia (SIH).

- Epithelioid hemangioendothelioma (EHE) is difficult to treat with traditional chemotherapy, prompting researchers to explore new therapies such as sirolimus and identify biomarkers for tumor aggressiveness.
- Scientists created a patient-derived xenograft (PDX) model from an advanced EHE patient to test sirolimus and to study serum levels of Growth/Differentiation Factor 15 (GDF-15) as a potential biomarker.
- The results indicated sirolimus was more effective than doxorubicin in reducing tumor growth and GDF-15 levels, establishing GDF-15 as a promising biomarker for EHE aggressiveness and potentially indicating the effectiveness of sirolimus in patients.
Article Synopsis
- Epithelioid hemangioendothelioma (EHE) is a rare type of cancer with unique features, but its natural history and best treatment practices are not well understood.
- The EURACAN project has created a registry to gather prospective data on newly diagnosed EHE patients to enhance understanding of the disease.
- The study will involve collecting comprehensive patient data from specialized hospitals to identify prognostic factors, treatment efficacy, and to monitor the disease's progression and outcomes over time.
Ghrelin modulates several biological functions via selective activation of the growth hormone secretagogue receptor (GHSR). GHSR agonists may be useful for the treatment of anorexia and cachexia, while antagonists and inverse agonists may represent new drugs for the treatment of metabolic and substance use disorders. Thus, the identification and pharmacodynamic characterization of new GHSR ligands is of high interest.
