Low-level laser (photobiomodulation) to prevent mouth sores during radiotherapy for oral cancer

Official title: A Pilot Study to Describe the Effect of Photobiomodulation in Reducing the Severity and Incidence of Oral Mucositis in Oral Cancer Patients Undergoing Radiation Treatment

Run by Peter MacCallum Cancer Centre, Australia · NCT07387978 · Data updated 2026-11-12

This study will try low-level laser therapy (photobiomodulation), given five times a week during radiotherapy, to reduce mouth sores in adults treated for oral cancer.

Is this trial a fit for you?

Likely a good fit

Adults (≥18) with histologically confirmed oral cavity cancer after surgery with clear margins (R0/R1), ECOG 0–1, intact oral mucosa, and planned radiotherapy ≥50 Gy with or without chemotherapy.

Probably not a fit

Patients with gross residual disease after surgery (R2), prior head and neck radiotherapy, recent cytotoxic chemotherapy, photosensitive disorders, existing oral ulceration, or poor performance status are unlikely to benefit from this protocol.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This single-center interventional study enrolls post-operative oral cavity cancer patients with clear margins who are scheduled for radiotherapy of ≥50 Gy, with or without chemotherapy. Participants will receive photobiomodulation using a THOR laser five times per week concurrent with their radiotherapy course. The trial will record incidence and severity of oral mucositis, pain levels, quality of life, analgesia needs, oral intake, trismus severity, and hospitalization rates. PBM is supported by prior literature and guideline recommendations and the device used has local regulatory approval.

Why it matters

Potential benefit: If successful, photobiomodulation could reduce how often and how severely mouth sores occur, lower pain and hospital admissions, and help patients maintain oral intake during radiotherapy.

How similar studies have gone: Multiple randomized trials and meta-analyses have shown PBM can prevent or reduce oral mucositis in head and neck cancer, and PBM is recommended in MASCC and NICE guidelines with device approval in Australia.
