Combining chemotherapy and immunotherapy for high-risk head and neck cancer patients after surgery

Postoperative Concurrent Chemoradiotherapy Followed by Anti-PD-1 Antibody Maintenance Therapy in High-Risk Locally Advanced Head and Neck Squamous Cell Carcinoma

PHASE2 · Cancer Institute and Hospital, Chinese Academy of Medical Sciences · NCT06170710

This study is testing if adding a new immune treatment to standard chemotherapy after surgery can help high-risk head and neck cancer patients stay cancer-free longer.

What this trial studies

This phase II clinical trial evaluates the effectiveness of adding an anti-PD-1 antibody to postoperative chemoradiotherapy in improving disease-free survival for patients with high-risk locally advanced head and neck squamous cell carcinoma (HNSCC). The study will enroll 173 patients who have undergone surgery for their cancer and will randomly assign them to receive either standard chemoradiotherapy or chemoradiotherapy plus the PD-1 antibody. The goal is to determine if the combination treatment is more effective than chemoradiotherapy alone in preventing cancer recurrence.

Who should consider this trial

Good fit: Ideal candidates include patients with histologically confirmed high-risk locally advanced head and neck squamous cell carcinoma who meet specific eligibility criteria.

Not a fit: Patients with low-risk head and neck cancer or those who cannot tolerate immunotherapy or chemoradiotherapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly improve survival rates for patients with high-risk head and neck cancer.

How similar studies have performed: Other studies have shown promising results with similar combinations of immunotherapy and chemoradiotherapy, suggesting potential for success in this approach.
