Quality of life and medical care for long-term sarcoma survivors in Germany (PROSa+)

Understanding Long-Term Sarcoma Survivorship: Risk Profiles, Outcomes and Unmet Needs - A Joint Project of Research, Sarcoma Centres and Patient Experts (PROSa+)

Observational Technische Universität Dresden · NCT07148193

This project will ask adults in Germany who were diagnosed with sarcoma at least five years ago to complete questionnaires and some interviews to see how cancer and its treatments affect their quality of life and medical care.

What this trial studies

PROSa+ is a multicenter observational study combining a one-time cross-sectional questionnaire of 1,600 long-term sarcoma survivors (paper or online), up to 60 qualitative interviews, and longitudinal analyses linking existing sarcoma registries and the earlier PROSa cohort (2017–2020). The study focuses on subgroups with potential long-term risks, including bone sarcoma survivors, extremity or trunk sarcomas after multimodal treatment, retroperitoneal sarcomas, GIST (with or without long-term TKI therapy), and young adults. Data collected include patient-reported outcomes, patient-reported experiences, and socioeconomic measures, with recruitment via clinical networks, registries, and patient organizations. Participants must be adults (≥18 years) and at least five years post initial sarcoma diagnosis, with or without active disease.

Who should consider this trial

Good fit: Adults (age ≥18) living in Germany who were diagnosed with a sarcoma at least five years ago, able to complete questionnaires in German, and with or without active disease are the ideal candidates.

Not a fit: People diagnosed less than five years ago, those with desmoid tumors, or individuals unable to complete a structured questionnaire (for example due to insufficient German language skills or cognitive impairment) are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the findings could identify unmet survivorship needs and inform improvements in follow-up care, supportive services, and health policy for long-term sarcoma survivors.

How similar studies have performed: Previous PROSa work (2017–2020) and other registry-based survivorship studies have documented quality-of-life and care issues in sarcoma survivors, but comprehensive long-term, mixed-methods data remain limited, making this approach comparatively novel.
