Summary
Ozone therapy may offer benefits for advanced head and neck cancer patients undergoing chemo-radiotherapy. While not significantly improving overall survival in this small study, it suggests potential positive effects warranting further investigation.
Area of Science:
- Oncology
- Experimental Therapeutics
Background:
- Advanced head and neck (H&N) tumors often present with hypoxia and ischemia, negatively impacting prognosis.
- Ozone therapy is explored for its potential to improve tissue oxygenation and treat ischemic conditions.
Purpose of the Study:
- To prospectively evaluate the clinical impact of systemic ozone therapy as an adjunct treatment for advanced H&N cancer patients receiving chemo-radiotherapy.
Main Methods:
- A prospective study involving 19 patients with advanced H&N tumors treated with radiotherapy and oral tegafur.
- A comparison between a group receiving additional intravenous chemotherapy and a group receiving systemic ozone therapy twice weekly during radiotherapy.
Main Results:
- The ozone therapy group was older and had more advanced disease (higher lymph node involvement and tumor stage) compared to the chemotherapy group.
- No significant difference in overall survival was observed between the chemotherapy (median 6 months) and ozone therapy (median 8 months) groups.
Conclusions:
- Despite limitations due to small sample size, the findings suggest a potential positive effect of adjuvant ozone therapy in advanced H&N cancer patients.
- Further research is warranted to explore the role of ozone therapy in chemo-radiotherapy for these challenging tumors.
