Using soluble B7-H3 levels to evaluate osteosarcoma prognosis

An Exploratory Research of Soluble B7-H3 Expression in Peripheral Blood as a Biomarker to Monitor Therapeutic Effect of Systemic Treatment for Osteosarcoma

Observational Peking University People's Hospital · NCT05942456

This study is testing if measuring a protein called soluble B7-H3 in the blood can help predict how well patients with high-grade osteosarcoma will do after treatment.

What this trial studies

This observational study aims to investigate the levels of soluble B7-H3 (sB7-H3) in serum as a potential biomarker for osteosarcoma. It focuses on patients with high-grade osteosarcoma who have not received systemic treatment prior to blood sampling. The study will utilize enzyme-linked immunosorbent assay (ELISA) to measure sB7-H3 levels and assess their correlation with clinical outcomes. The goal is to better understand the clinical significance of sB7-H3 in the context of osteosarcoma treatment and prognosis.

Who should consider this trial

Good fit: Ideal candidates are patients with high-grade osteosarcoma who are treatment-naive and can tolerate standard chemotherapy protocols.

Not a fit: Patients who cannot tolerate blood drawing or have incomplete medical records may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new biomarker for predicting treatment outcomes in osteosarcoma patients.

How similar studies have performed: While there is increasing evidence linking sB7-H3 to prognosis in various malignancies, the specific application to osteosarcoma is novel and not extensively tested.
