Liquid biopsy (ctDNA) blood test for bone and soft tissue sarcoma

Prospective Clinical Evaluation of Circulating Tumor DNA Liquid Biopsy in Sarcoma Patients

Observational Wake Forest University Health Sciences · NCT06958107

This study will test whether low-pass whole genome sequencing of a blood liquid biopsy can detect tumor DNA in adults and children with bone or soft tissue sarcomas.

What this trial studies

This observational study will collect blood samples from adult and pediatric patients with suspected or confirmed bone and soft tissue sarcomas, including lipomatous lesions like ALT/WDLS. Investigators will use low-pass whole genome sequencing (LP-WGS) to search for circulating tumor DNA (ctDNA) and compare those findings with clinical status, imaging, and pathology. The study includes patients across disease states: non-metastatic resectable, metastatic unresectable, and patients under surveillance after therapy. The aim is to see if LP-WGS liquid biopsy can support diagnosis, prognosis, treatment monitoring, and early detection of recurrence in sarcoma patients.

Who should consider this trial

Good fit: People of any age with suspected or confirmed bone or soft tissue sarcoma (including suspected ALT/WDLS) who can come to a participating center for blood draws and follow-up are eligible.

Not a fit: Patients who do not have sarcoma or whose tumors do not shed measurable ctDNA (for example very small or certain low-shedding subtypes) are unlikely to derive direct benefit from the test.

Why it matters

Potential benefit: If successful, this approach could provide a noninvasive tool to help detect and monitor sarcoma, inform treatment decisions, and identify recurrence earlier.

How similar studies have performed: Liquid biopsy and ctDNA methods have shown promise in other cancers and in early sarcoma reports, but sarcoma-specific LP-WGS testing is still emerging and not yet widely validated.
