What Researchers Did
Researchers reviewed the findings from 15 randomized controlled clinical trials investigating the use of hyperbaric oxygen as an adjunct to radiotherapy.
What They Found
Among the 15 trials, three demonstrated a highly significant benefit from hyperbaric oxygen in radiotherapy, while six showed useful but not statistically significant margins. However, the observed increase in tumour control was partially offset by an increase in adverse effects on normal tissues.
What This Means for Canadian Patients
While hyperbaric oxygen showed some promise in past studies for improving tumour control during radiotherapy, its benefits were often accompanied by increased side effects. Newer, simpler methods like carbogen breathing are being explored as potentially safer ways to enhance radiation effectiveness.
