Cancer cells often flourish in an environment characterized by low oxygen levels and chronic inflammation. This milieu is typically rich in reactive oxygen species (ROS), which are known to contribute to the onset and progression of cancer. A study highlighted by Mayo Clinic researchers acknowledges that nearly all cancer types exhibit elevated ROS levels that foster cancer growth. Targeting these species through redox-based therapies has been a focus, aiming to shrink tumors and mitigate the side effects of conventional cancer treatments.
Molecular hydrogen, with its notable antioxidant and anti-inflammatory capabilities, has therefore become a molecule of interest for researchers and clinicians, especially in countries like Japan, China, and Korea where its medical application has seen significant investigation and even clinical use.
Research spanning from cell studies to clinical trials has shown that hydrogen gas can counteract the deleterious effects of chemotherapy and may inhibit the growth of cancer cells and tumors through its ROS-neutralizing capabilities. This was notably underscored in a collaborative study in 2019 by researchers from Southern Medical University, Hershey Medical Center, and the University of Bern. They posited that hydrogen gas could induce cancer cell death and recommended further exploration into its mechanisms and benefits.
Due to its minute size, molecular hydrogen can permeate the body easily, reaching organs and cells, thus offering a potentially simple yet effective approach to combating cancer—a disease where survival rates are often low. Hydrogen gas is also non-toxic, cost-effective, and easy to administer, which adds to its appeal in medical settings.
An investigation conducted by Beijing’s University of Technology’s Molecular Hydrogen Research Center in 2018 concluded that hydrogen inhalation therapy might be beneficial for ovarian cancer, with observations of reduced cancer cell growth and migration after six weeks of treatment.
Moreover, hydrogen therapy showed promise in managing non-small-cell lung cancer (NSCLC), one of the most commonly diagnosed cancers in the United States. Clinical trials revealed that hydrogen inhalation therapy alone, or in combination with chemotherapy, targeted therapy, or immunotherapy, could help control tumor progression and reduce treatment side effects.
Hydrogen gas, also serving as a scavenger for hydroxyl radicals and peroxynitrite, could potentially mitigate the harmful effects of chemotherapy and radiotherapy. A 2011 clinical trial associated with the University of Pittsburgh indicated that patients with liver tumors undergoing radiotherapy experienced reduced oxidative stress when consuming hydrogen-rich water, without adversely affecting the treatment’s anti-tumor efficacy.
Given its ability to diffuse rapidly into tissues and cells and cross the blood-brain barrier, molecular hydrogen is a promising agent for further research, particularly in the treatment of brain tumors.
The exploration of molecular hydrogen in cancer therapeutics is indicative of a broader awakening to its possible benefits. As the scientific community continues to investigate, the integration of hydrogen-based modalities into cancer treatment protocols remains a promising frontier.
