Liquid biopsy in cartilaginous bone tumors to help diagnose and monitor chondrosarcoma

Official title: Clinical Applicability of Liquid Biopsy in Intermediate and Malignant Cartilaginous Neoplasms - A Prospective Cohort Study

Run by Medical University of Graz · NCT07492823 · Data updated 2026-11-12

Researchers are testing a non-invasive blood test to see if it can help diagnose, predict prognosis, and detect early recurrence of chondrosarcoma and related cartilaginous tumors.

Is this trial a fit for you?

Likely a good fit

Candidates are adults with semimalignant or malignant cartilaginous tumors (including ACT and chondrosarcoma G1/2/3, or dedifferentiated chondrosarcoma) who are planned for definitive primary tumor surgery.

Probably not a fit

Patients who have already received tumor-specific systemic therapy prior to enrollment may not benefit from this approach.

What this trial studies

This observational cohort study investigates whether liquid biopsy biomarkers, including IDH1/2 mutations and cytokine profiles, can aid in diagnosing intermediate to malignant cartilaginous tumors and in monitoring disease alongside or as an alternative to imaging. Patients with semimalignant or malignant cartilaginous tumors who undergo surgery are eligible. The study analyzes laboratory biomarker data and molecular pathology from blood samples collected over time to explore correlations with tumor characteristics and outcomes. It aims to improve timely diagnosis, prognosis estimation, and recurrence detection while reducing reliance on cost-intensive, radiation-exposing imaging. The exact primary questions are not fully detailed in the available description.

Why it matters

Potential benefit: If successful, patients could benefit from a non-invasive test that helps with early diagnosis, prognosis, and surveillance of cartilaginous bone tumors.

How similar studies have gone: Liquid biopsy approaches have shown promise in other solid tumors, but application to cartilaginous bone tumors remains exploratory in this setting.
