Investigating neutrophils in bone tumors

Assessment of the Presence, and Characterization, of Tumor-associated Neutrophils in Bone Sarcomas: Pilot Study

Observational Université de Reims Champagne-Ardenne · NCT04867421

This study is looking at the role of certain immune cells in bone tumors to see how they might affect patients with osteosarcoma and chondrosarcoma.

What this trial studies

This observational study aims to explore the presence of tumor-associated neutrophils (TANs) in patients with osteosarcoma and chondrosarcoma. Adult patients undergoing surgery for these bone tumors will be invited to participate during their preoperative consultations. The study will involve collecting tumor samples and demographic data, as well as assessing the immune cell profile and PDL-1 status of the tumors. The findings could provide insights into the role of neutrophils in these cancers.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older diagnosed with osteosarcoma or chondrosarcoma who are scheduled for surgery.

Not a fit: Patients with medical histories that may compromise the study protocol or those who are pregnant or breastfeeding may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of the immune environment in bone sarcomas, potentially leading to improved treatment strategies.

How similar studies have performed: While the specific focus on neutrophils in bone sarcomas is novel, similar studies in other cancer types have shown promising results regarding the role of immune cells.
