What Researchers Did
The researchers reviewed the existing evidence regarding the use of hyperbaric oxygen in conjunction with radiation therapy for cancer treatment.
What They Found
The researchers found that despite some impressive results in studies, particularly for head and neck tumours, it was not unequivocally demonstrated that hyperbaric oxygen radiation therapy was superior to conventional methods. They noted that any survival gain from hyperbaric oxygen would likely be limited, especially in advanced disease stages, though even a 5% to 10% improvement in survival could save many lives.
Canadian Relevance
This study has no direct Canadian connection.
Study Limitations
A key limitation highlighted by the researchers was the lack of unequivocally demonstrated superiority of hyperbaric oxygen over conventional radiotherapy, necessitating further well-controlled studies.
