What Researchers Did
Researchers reviewed the historical and emerging applications of hyperbaric oxygen therapy (HBO) in combination with radiotherapy for treating malignant tumors.
What They Found
Historically, hyperbaric oxygen therapy (HBO) combined with simultaneous radiotherapy significantly improved local control and survival in some head and neck and uterine cervix cancers. More recently, radiotherapy immediately after HBO therapy appeared safe and effective in patients with high-grade gliomas, potentially protecting normal tissues.
What This Means for Canadian Patients
While not a standard treatment, hyperbaric oxygen therapy (HBO) combined with radiotherapy could offer a future strategy to improve outcomes for Canadian cancer patients, particularly those with hypoxic tumors. This approach aims to enhance radiation effectiveness and potentially reduce side effects, but further research is needed before it becomes widely available.

Study Limitations
The review highlights the need for further prospective studies to accurately determine the benefits of radiotherapy immediately after HBO therapy for various cancers.
