TL;DR
Breathing or drinking hydrogen may help protect healthy body parts from the harsh side effects of cancer radiation treatment — without making the treatment less effective at fighting the tumor. This is exciting because it could help cancer patients feel better during treatment without getting in the way of their recovery.
Key Finding
Molecular hydrogen did not significantly affect tumor response to radiotherapy (risk ratio = 0.98), suggesting it protects healthy tissue from radiation damage without reducing radiation's effectiveness against cancer cells.
Summary
This systematic review and meta-analysis (a study that combines results from multiple clinical trials) examined whether molecular hydrogen protects cancer patients from the harmful side effects of radiation therapy without also protecting tumors from the radiation meant to destroy them. Researchers pooled data from 7 clinical studies involving 222 adult cancer patients. They found that hydrogen reduced radiation-related side effects and improved quality of life, and — critically — did not appear to shield tumors from treatment.
Practical Takeaway
For people undergoing radiation therapy for cancer, this meta-analysis suggests that molecular hydrogen may help reduce treatment side effects without interfering with the cancer-fighting effects of radiation. However, the analysis was based on only 7 small studies with 222 total patients, so these findings should be considered preliminary. Anyone considering hydrogen as a complement to cancer treatment should consult their oncologist.
Abstract (excerpt)
Radiotherapy and concurrent chemoradiotherapy (CCRT) are widely used for cancer treatment but are frequently associated with radiation-induced toxicities. Molecular hydrogen has been proposed as a potential radioprotective agent because it protects normal tissues from oxidative damage. However…
