What Researchers Did
Researchers reported on a 38-year-old man with glioblastoma who received a modified standard treatment plan, including a ketogenic diet, several supplements, and hyperbaric oxygen therapy (HBOT) at 2.5 ATA for 60 minutes, five times a week.
What They Found
After 9 months of treatment, the patient's body weight was reduced by about 19%, and his seizures and left limb weakness resolved. Biomarkers indicated reduced blood glucose, elevated urinary ketones, and normalized levels of insulin, triglycerides, and vitamin D, suggesting reduced tumour metabolic activity. Pre-surgical metabolic therapy also showed signs of therapeutic benefit, with reduced tumour cell invasion.
Canadian Relevance
This study has Canadian relevance as it includes Canadian authors. However, glioblastoma is not a Health Canada-recognised indication for hyperbaric oxygen therapy.
Study Limitations
As a single case report, this study's findings cannot be generalized to other patients, and it is difficult to determine the specific contribution of hyperbaric oxygen therapy among the many interventions used.
