Using a risk prediction tool to help treat patients with soft-tissue sarcomas

The Value of a Risk Prediction Tool (PERSARC) for Effective Treatment Decisions of Soft-tissue Sarcomas Patients

NA · Leiden University Medical Center · NCT05741944

This study is testing a new tool to help doctors make better treatment choices for patients with high-grade soft-tissue sarcomas and see if it improves their understanding and satisfaction with their care.

What this trial studies

This clinical trial evaluates the effectiveness of a personalized risk assessment tool called PERSARC in aiding treatment decisions for patients with high-grade extremity soft-tissue sarcomas. Participants will be divided into two groups: one receiving standard care and the other receiving care informed by PERSARC during consultations with their oncological or orthopedic surgeons. The study aims to reduce decisional conflict and enhance patient knowledge regarding treatment options. Outcomes will be assessed at multiple time points after the treatment decision is made to evaluate the tool's impact on patient involvement and satisfaction.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with a histologically diagnosed grade 2-3 soft-tissue sarcoma in their extremities who have not yet established a treatment plan.

Not a fit: Patients requiring treatments not included in the PERSARC tool, such as those needing chemotherapy or isolated limb perfusion, may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could empower patients with better knowledge and confidence in their treatment decisions, potentially leading to improved outcomes.

How similar studies have performed: While the use of personalized risk assessment tools in oncology is gaining traction, this specific approach with PERSARC is relatively novel and has not been extensively tested in prior studies.
