Adaptive radiotherapy for oropharynx cancer

Adaptive RadioTherapy for Locally Advanced OroPharynx Cancer (ART-OPC) A Phase II Randomized Trial

Phase 2 Interventional Centre hospitalier de l'Université de Montréal (CHUM) · NCT04901234

This study is testing if adjusting radiation treatment using MRI during therapy can help people with advanced throat cancer swallow better after their treatment compared to standard care.

What this trial studies

This phase II randomized trial aims to evaluate the effectiveness of mid-treatment MRI-based radiotherapy adaptation compared to standard care in patients with squamous cell carcinoma of the oropharynx. The study focuses on patients with T3-T4 tumors undergoing curative chemoradiation. The primary goal is to assess the impact of treatment adaptation on patient-reported dysphagia six months post-treatment. By utilizing MRI technology, the trial seeks to improve treatment outcomes by addressing anatomical changes during the radiotherapy course.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with biopsy-proven squamous cell carcinoma of the oropharynx and T3-T4 tumors planned for curative radiotherapy.

Not a fit: Patients with previous head and neck radiation, certain medical conditions, or contraindications to MRI may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce dysphagia and improve the quality of life for patients undergoing treatment for oropharynx cancer.

How similar studies have performed: While the use of MRI for treatment adaptation is gaining traction, there is currently no established clinical advantage demonstrated in head and neck cancer, making this approach relatively novel.
