Carbon ion re-radiotherapy for recurrent head-and-neck cancer

Carbon Ion Re-Radiotherapy in Patients With Recurrent or Progressive Locally Advanced Head-and-Neck Cancer: A Phase-II Study to Evaluate Toxicity and Efficacy

Not applicable Interventional University Hospital Heidelberg · NCT04185974

This study is testing if a new type of radiation therapy called carbon ion re-radiotherapy can help people with recurrent head-and-neck cancer live longer and feel better compared to regular radiation treatments.

What this trial studies

This clinical trial evaluates the effectiveness of carbon ion re-radiotherapy (reCIRT) compared to conventional photon re-irradiation in patients with recurrent or progressive locally advanced head-and-neck cancer. The study focuses on assessing safety, local progression-free survival, overall survival, and quality of life in a cohort that has limited treatment options after initial therapies. Participants must have experienced local recurrence or progression after prior radiation therapy and meet specific eligibility criteria. The trial aims to provide insights into the potential benefits of reCIRT in managing this challenging patient population.

Who should consider this trial

Good fit: Ideal candidates include adults with locally recurrent or progressive head-and-neck cancer who have previously undergone radiation therapy and are not candidates for salvage surgery.

Not a fit: Patients with distant metastases, prior re-irradiation in the same field, or those who have not recovered from acute toxicities of previous treatments may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could offer a new treatment option that minimizes toxicity while improving survival and quality of life for patients with recurrent head-and-neck cancer.

How similar studies have performed: While carbon ion therapy is a relatively novel approach, previous studies have shown promising results in similar patient populations, indicating potential for success.
