An Observational Study on Epithelioid Sarcoma

The present prospective national study aims to provide a description of the population affected by ES, an insight into the natural history of the disease and an answer some on the outstanding questions on its management. Also, it will focus on enhancing any differences between the two ES variants (classical-type and proximal-type) in order gain a better understanding of the disease, tailor the treatment and lastly improve outcome.

• Treatment for Epitheloid Sarcoma (Other): Treatment Epitheloid Sarcoma according the disease guideline

Primary outcomes

• Type of treatment given to patients with ES [From diagnosis until the date of death from any cause assessed up to 60 months]: Number of chemotherapy treatment received patients affected by ES

Secondary outcomes

• Radiotherapy treatments [From the time of diagnosis and then every 6 months up to 60 months]: Number of patients affected by localized ES who received radiotherapy
• Chemotherapy treatments [From the time of diagnosis and then every 6 months up to 60 months]: Number of patients affected by localized ES who received chemotherapy
• Predictive biomarkers for response [At time of diagnosis and at the time of any progression where a biopsy is performed up to 60 months]: Tumor biomarkers expression in tumor tissue of patients affected by ES
