Evaluating Photoacoustic Imaging for Head and Neck Cancer

Pilot Study to Evaluate Photoacoustic Imaging in Head and Neck Cancer

Sunnybrook Health Sciences Centre · NCT04428515

This study is testing a new imaging technique to see how head and neck cancer patients' lymph nodes change during their treatment with radiation, with or without chemotherapy.

What this trial studies

This pilot study aims to assess the changes in lymph node involvement in patients with head and neck cancer during their radiotherapy treatment, with or without chemotherapy, using photoacoustic (PA) imaging. Up to 50 participants will be recruited and imaged five times over the course of their treatment, which lasts up to seven weeks. The study will correlate changes in PA imaging parameters with radiological responses assessed via MRI 10 to 12 weeks post-treatment. The goal is to enhance understanding of treatment responses through innovative imaging techniques.

Who should consider this trial

Good fit: Ideal candidates are patients with histologically confirmed head and neck carcinoma who have not received prior treatment and are scheduled for radiotherapy.

Not a fit: Patients with previously treated head and neck cancer or those with non-measurable disease may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could improve the monitoring of treatment responses in head and neck cancer, leading to better patient outcomes.

How similar studies have performed: While the use of photoacoustic imaging is a novel approach in this context, similar imaging techniques have shown promise in other studies for monitoring cancer treatment responses.
