Hyperbaric oxygen therapy for late radiation-associated tissue necroses: is it safe in patients with locoregionally recurrent and then successfully salvaged head-and-neck cancers?

What Researchers Did

Researchers conducted a retrospective matched-pair study to investigate if hyperbaric oxygen therapy (HBOT) for late radiation-associated tissue necroses increases cancer re-recurrence risk in successfully salvaged head-and-neck cancer patients.

What They Found

The study found more cancer re-recurrences in the HBOT group (9 of 11 patients) compared to the non-HBOT group (4 of 11 patients), with 5-year disease-free survival rates of 32.7% versus 70.0% respectively (hazard ratio 3.2, p = 0.048). Re-recurrences also developed rapidly after HBOT in 6 patients, and 3 patients experienced unusual re-recurrences.

What This Means for Canadian Patients

Canadian patients with successfully salvaged head-and-neck cancers considering hyperbaric oxygen therapy for radiation-associated tissue necroses should discuss the potential increased risk of cancer re-recurrence with their healthcare providers. This information can help inform shared decision-making regarding treatment options.

Canadian Relevance

This study has no direct Canadian connection.

Study Limitations

The study's retrospective design and small sample size of 22 patients limit the generalizability and strength of its conclusions.
