What Researchers Did
This cohort study evaluated symptoms of late radiation toxicity, side effects, and quality of life in breast cancer patients treated with hyperbaric oxygen therapy (HBOT) in 5 Dutch facilities.
What They Found
Researchers found that pain scores significantly decreased from 43.4 before HBOT to 29.7 after 3 months (p < 0.001), and breast symptoms decreased from 44.6 to 28.9 (p < 0.001) over the same period. Arm symptoms also significantly decreased from 38.2 to 27.4 (p < 0.001), with all quality of life domains improving. The most common side effects were myopia (57.3%) and mild barotrauma (17.8%), with moderate/severe side effects in 3.2% of patients.
What This Means for Canadian Patients
For Canadian breast cancer patients experiencing late radiation toxicity, hyperbaric oxygen therapy could offer a potential treatment option to alleviate pain and improve quality of life. Patients should discuss the potential benefits and common side effects, such as temporary vision changes, with their healthcare providers.
Canadian Relevance
This study was conducted in Dutch facilities and does not have a direct Canadian connection.
Study Limitations
As a cohort study, this research lacks a control group, which limits the ability to definitively attribute improvements solely to HBOT.
