Geriatric Assessmen of Elderly "Unsuited" Patients Receiving Trabectedin in First Line Treatment For Advanced Soft Tissue Sarcomas (STS)

The aim of the non-interventional study is to prospectively collect and analyze data on the geriatric assessment of patients undergoing systemic 1st line therapy with trabectedin with focus on patients who have been assessed by the treating physician as being unsuited to receive standard chemotherapy with anthracyclines and / or ifosfamide. Trabectedin will be used according to the local SmPC. Modification of the treatment schedule should follow the standard medical practice at the discretion of the treating physician and is not part of this Observational Plan.
