What Researchers Did
Researchers conducted a prospective controlled trial comparing radiotherapy in hyperbaric oxygen (HBO) with radiotherapy in air for 104 patients with head and neck cancer.
What They Found
The study found significantly higher survival and local control rates in the HBO group compared to the air group. No differences in normal tissue effects were observed, with the greatest benefit of HBO seen in less advanced tumors.
What This Means for Canadian Patients
For Canadian patients with head and neck cancer, these findings suggest that hyperbaric oxygen therapy combined with radiotherapy could potentially improve treatment outcomes, particularly for less advanced disease. This approach might offer better local control and survival without increasing normal tissue side effects.
Canadian Relevance
This study does not indicate any direct Canadian connection or involvement.
Study Limitations
A limitation is that this study was conducted in 1986, and modern treatment protocols and technologies may differ.
