H2 Therapy for Advanced Lung Cancer: Tumor Control & Medication ReliefScientific Research
Hydrogen Therapy Helps with Lung Cancer
Hydrogen therapy slows the progression of tumors in non-small cell lung cancer and reduces the side effects of conventional treatments. This is according to results from a study conducted at Fuda Cancer Hospital. The study involved 58 patients who were treated with hydrogen therapy, either alone or in combination with other treatments, to observe its effects on the cancer and their overall condition. The study was approved by the hospital’s Ethics Committee. Here’s how the study was conducted. Patients were divided into five groups depending on their treatment plans. The first group received only hydrogen therapy. The second group did not receive any treatment and acted as a control. The remaining three groups received a combination of hydrogen therapy with chemotherapy, targeted therapy, or immunotherapy. The main goal was to check whether hydrogen therapy could not only control the cancer but also mitigate the adverse side effects usually associated with conventional treatments.
The cancer develops more slowly in patients with hydrogen therapy.
In hydrogen therapy, patients inhale hydrogen mixed with oxygen for 4 to 6 hours each day over five months. The control group underwent a sham procedure with only oxygen. The patients were closely monitored. They underwent imaging tests, such as CT scans and MRI, every month to check for changes in their tumors.
Hydrogen therapy provides even better results in combination with traditional treatment.
The benefits were even more significant in the groups that combined hydrogen therapy with conventional treatments. Patients in these groups had a longer progression-free survival. Over 10 months for the group with immunotherapy with hydrogen. Over 9 months for the group with targeted therapy with hydrogen. 8 and a half months for the group with chemotherapy with hydrogen. These results show that hydrogen therapy can enhance the effectiveness of existing cancer treatment methods.
Hydrogen therapy reduces the side effects of conventional treatments.
Hydrogen therapy has helped to reduce the side effects of conventional treatments. Patients experienced fewer symptoms such as cough, chest pain, and shortness of breath. They also had fewer drug-related side effects like nausea, vomiting, rashes, and dizziness. In the group treated with chemotherapy with hydrogen, there was a significant reduction in symptoms such as feverishness, anemia, and low platelet counts in the blood. This improvement in managing side effects can significantly enhance the quality of life for patients.
The study conducted at the Fuda Cancer Hospital shows that hydrogen therapy can be a safe and effective way to support cancer treatment, facilitating patients to tolerate drugs from conventional treatment protocols and reducing the likelihood of severe side effects.

original title: Hydrogen therapy can be used to control tumor progression and alleviate the adverse events of medications in patients with advanced non-small cell lung cancer
Chemotherapy, targeted therapy, and immunotherapy are used against advanced non-small cell lung cancer. A clinically efficacious method for relieving the adverse events associated of such therapies is lacking. Fifty-eight adult patients were enrolled in our trial to relieve pulmonary symptoms or the adverse events of drugs. Twenty patients who refused drug treatment were assigned equally and randomly to a hydrogen (H2)-only group and a control group. According to the results of tumor-gene mutations and drug-sensitivity tests, 10, 18, and 10 patients were enrolled into chemotherapy, targeted therapy, and immunotherapy groups in which these therapies were combined with H2-therapy, respectively. Patients underwent H2 inhalation for 4–5 hours per day for 5 months or stopped when cancer recurrence. Before study initiation, the demographics (except for tumor-mutation genes) and pulmonary symptoms (except for moderate cough) of the five groups showed no significant difference. During the first 5 months of treatment, the prevalence of symptoms of the control group increased gradually, whereas that of the four treatment groups decreased gradually. After 16 months of follow-up, progression-free survival of the control group was lower than that of the H2-only group, and significantly lower than that of H2 + chemotherapy, H2 + targeted therapy, and H2 + immunotherapy groups. In the combined-therapy groups, most drug-associated adverse events decreased gradually or even disappeared. H2 inhalation was first discovered in the clinic that can be used to control tumor progression and alleviate the adverse events of medications for patients with advanced non-small cell lung cancer. This study was approved by the Ethics Committee of Fuda Cancer Hospital of Jinan University on December 7, 2018 (approval No. Fuda20181207), and was registered at ClinicalTrials.gov (Identifier: NCT03818347) on January 28, 2019.

INTRODUCTION
Lung cancer is the most prevalent form of cancer-related disease worldwide, of which non-small-cell lung cancer (NSCLC) accounts for ~85%.1 Many patients are at an advanced stage of lung cancer when the diagnosis is made,2 and progression-free survival (PFS) is usually < 6 months.3 In these cases, the tumors cannot be resected; therefore, chemotherapy,4 targeted therapy5 and immunotherapy6 are common treatment options. Each treatment has different indications, and also produces different adverse events. Serious adverse events (e.g., severe granulocytopenia,7 thrombocytopenia,8 abnormal liver function9) often lead to significant changes in vital signs and patients are forced to stop or change medications.
Hydrogen (H2) is an anti-inflammatory, antioxidant, and antiapoptotic molecule. It can diffuse into mitochondria, neutralize reactive oxygen species selectively,1011 and restore cell viability by regulating expression of various genes.12 In animal experiments, H2 has been demonstrated to alleviate the serious adverse events caused by chemotherapy,1314 and targeted therapy.15 H2 has been used in clinical trials of multiple non-neoplastic diseases, indicating the safety of H2 gas inhalation.1617
In the present study, H2 therapy was used to control cancer progression and alleviate the adverse events of multiple standard therapies in patients with advanced NSCLC.
SUBJECTS AND METHODS
The inclusion and exclusion criteria
This clinical trial was registered at ClinicalTrials.gov (Identifier: NCT03818347) on January 28, 2019. The enrolled patients were divided into five groups according to the precise medical test results of tumors. The inclusion criteria were patients with: stage-III or -IV NSCLC diagnosed by imaging and pathology with specialist doctor; tumor number 1–6; maximum tumor length < 2 cm; Karnofsky performance status (KPS) score ≥ 70; expected survival time > 6 months; platelet count ≥ 80 × 109/L; white blood cell count ≥ 3 × 109/L; neutrophil count ≥ 2 × 109/L; hemoglobin ≥ 80 g/L. The exclusion criteria were patients with: a cardiac pacemaker; brain metastasis; grade-3 hypertension or diabetic complications; severe cardiac and pulmonary dysfunction. This study protocol received ethical approval from the Ethics Committee of Fuda Cancer Hospital of Jinan University on December 7, 2018 (approval No. Fuda20181207). Written informed consent was obtained from each patient.
Subjects
Between June and September 2019, 58 patients with advanced NSCLC at Fuda Cancer Hospital of Jinan University met the inclusion criteria mentioned above and were enrolled in the study. Thirty-four patients had surgery before enrollment, and 24 patients were in advance stage when diagnosis.
Immunohistochemical assays of the ratio of programmed cell death-1: programmed cell death-1 ligands, tumor mutation burden, and microsatellite instability in tumor specimens were undertaken. Based on the results, 10 patients were administered a drug based on antibodies against programmed cell death-1 (Nivolumab [Opdivo®, Bristol-Myers Squibb, New York, NY, USA] or Pembrolizumab [Keytruda®, Merck, Kennyworth, NJ, USA]). Through detection of gene mutations in tumor specimens, 18 patients were selected to be given targeted therapy. Patients with a mutation in the epidermal growth factor receptor gene were administered Osimertinib (Tagrisso®, AstraZeneca, London, UK), Gefitinib (Iressa®, AstraZeneca) or Erlotinib (Tarceva®, Roche, Basel, Switzerland). Patients with a mutation in the anaplastic lymphoma kinase gene or receptor tyrosine kinase-1 gene were administered Crizotinib (Xalkori®, Pfizer, New York, NY, USA). Based on the data of drug-sensitivity tests, 10 patients were administered chemotherapy (Cisplatin or Carboplatin [both from Qilu Pharmaceutical, Haikou, Hainan Province, China]).
The remaining 20 patients who were not sensitive to common drugs or who failed to respond to treatment by common drugs were distributed evenly in the H2-monotherapy group or control group. Three groups of patients who had H2 treatment combined with another treatment (immunotherapy, targeted therapy or chemotherapy) started therapy before enrollment of our clinical trial. Most of those patients experienced significant effects on cancer-related lung symptoms after taking combination therapy, but new drug-related adverse events emerged. Lung symptoms or drug-related adverse events were compared before and after H2 treatment. The comparison of lung symptoms before hydrogen treatment and the changes of tumor or drug-related symptoms in each group after hydrogen treatment are shown in Figure 1. This study followed the Transparent Reporting of Evaluations with Nonrandomized Designs (TREND) Statement.

H2 inhalation
H2 was produced by a H2–oxygen nebulizer (H2 66.7% and oxygen 33.3%; maximum gas flow, 3 L/min; AMS-H-03, Shanghai Asclepius Meditec, Shanghai, China). The control group underwent a sham procedure (H2 0% and oxygen 33.3%; maximum gas flow 3 L/min; Shanghai Asclepius Meditec). Enrolled patients inhaled the gas mixture for 4–6 hours every day and underwent imaging examination every month until the existing lesions progressed significantly or new metastases appeared. PFS was calculated from the start of H2 inhalation to tumor progression. All patients received computed tomography or magnetic resonance examination every month. If the existing tumors grew up significantly or new metastases appeared, it is considered as tumor progression.
Pulmonary symptoms and drug-associated adverse events
The respiratory function of enrolled patients before H2 therapy was assessed by very experienced respiratory physicians using a pulmonary function tester (Autospiro AS-507; Minato Medical Science, Tokyo, Japan). Pulmonary tumor-related symptoms and the KPS score of all patients before H2 inhalation were evaluated. The adverse events of chemotherapy, targeted therapy or immunotherapy were assessed by the same respiratory physicians according to Common Terminology Criteria for Adverse Events 5.0.
Statistical analyses
Before H2 treatment, the demographics and tumor-associated symptoms of patients were compared using chi-squared and Fisher’s exact tests; respiratory function and the KPS score were compared using one-way analysis of variance and Bonferroni’s multiple comparison test. After H2 treatment, each tumor-associated symptom and drug-associated adverse event was compared using linear regression analysis; the PFS of each group was compared by one-way analysis of variance and Bonferroni’s multiple comparison test. P < 0.05 was considered significant difference. Analyses were done using Prism 5.0 (GraphPad, San Diego, CA, USA).
RESULTS
Clinical data of advanced non-small cell lung cancer patients with H2 inhalation treatment
Patients underwent H2 inhalation per day for 5 months or stopped the inhalation when cancer relapsed. There was no significant difference in most patient characteristics (e.g., sex) in each group. However, the targeted therapy–H2-therapy group had a higher proportion of tumor-gene mutations than the other four groups (P = 0.005; Table 1).

Pulmonary signs and symptoms of advanced non-small cell lung cancer patients with H2 inhalation treatment
Before the start of H2 therapy, there was no significant difference in pulmonary function or the KPS score among the five groups of patients (Table 2). The prevalence of most pulmonary symptoms (e.g., mild dyspnea, non-cardiac chest pain, pleural effusion, and hemoptysis) was similar among groups. The prevalence of most pulmonary symptoms in the control group, H2-monotherapy group, and immunotherapy–H2-therapy group was higher than that in the target therapy–H2-therapy group and chemotherapy–H2-therapy group (P = 0.0137).

Tumor-associated symptoms of advanced non-small cell lung cancer patients with H2 inhalation treatment
At the beginning of H2 treatment, the prevalence of tumor-associated symptoms in the control group and H2-monotherapy group was similar (P = 0.9994). With prolongation of the treatment time, in the control group, the prevalence of moderate cough (P = 0.0023), mild dyspnea (P = 0.0019), mild non-cardiac chest pain (P = 0.0006), mild pleural effusion (P = 0.0023), and mild hemoptysis (P = 0.0028) increased significantly (Figure 2A). In the H2-monotherapy group, the prevalence of moderate cough (P = 0.0014), mild dyspnea (P = 0.0247), mild non-cardiac chest pain (P = 0.0136), mild pleural effusion (P = 0.0015), and mild hemoptysis (P = 0.0048) decreased significantly (Figure 2B).
Tumor-associated symptoms varied with the inhalation time of hydrogen (H2).Note: (A) Control group (inhalation of 33.3% oxygen gas and no H2 (n = 10). (B) H2 only group (inhalation of 66.7% H2 + 33.3% O2) (n = 10). Each tumor-associated symptom was compared using linear regression analysis.
Drug-associated adverse events of advanced non-small cell lung cancer patients with H2 inhalation treatment
At the beginning of H2 treatment, the prevalence of tumor-associated symptoms in the three groups was similar (P = 0.5120), but drug-associated symptoms in the three groups were quite different (Figure 3). With the prolongation of treatment time, the prevalence of cough and non-cardiac chest pain (P = 0.0013), maculopapular rash (P = 0.0021), hepatobiliary disease (P = 0.0064), and dizziness and headache (P = 0.0111) decreased significantly, but diarrhea did not (P = 0.4144) (Figure 3A). In the target therapy–H2-therapy group, the prevalence febrile granulocytopenia (P = 0.0026), nausea and vomiting (P = 0.0051), maculopapular rash (P < 0.0001), insomnia (P = 0.0144), and oral mucositis (P = 0.0007) decreased significantly (Figure 3B). In the chemotherapy–H2-therapy group, the prevalence of febrile granulocytopenia (P = 0.0086), anemia and thrombocytopenia (P = 0.0009), constipation and diarrhea (P = 0.0053) and anorexia (P = 0.0129) decreased significantly, but nausea and vomiting did not (P = 0.0720; Figure 3C).
Drug-associated symptoms varied with the inhalation time of hydrogen (H2).Note: (A) Immunotherapy-H2 group (n = 10). (B) Target-H2 therapy group (n = 18). (C) Chemotherapy-H2 therapy group (n = 10). Drug-associated adverse event was compared using linear regression analysis.
PFS of advanced non-small cell lung cancer patients with H2 inhalation treatment
After 16 months of follow-up, all 58 patients developed tumor progression. PFS for the control group was 4.4 ± 1.2 months, whereas that for the H2-only group was 7.9 ± 2.2 months, H2-immunotherapy group was 10.1 ± 2.6 months, H2-targeted therapy group was 9.4 ± 3.1 months, and H2-chemotherapy group was 8.5 ± 3.0 months. PFS of the four treatment groups was longer than that of the control group, and that of the three H2 therapy-combination groups was prolonged significantly (Figure 4).

DISCUSSION
Molecular H2 has been used to treat pulmonary symptoms in animal models of acute lung injury,18192021 asthma22 and chronic obstructive pulmonary disease.232425 The principle of H2 therapy includes inhibition of secretion of cytokines such as interleukin-4, interleukin-13,22 interleukin-6 and tumor necrosis factor-α.15 H2 therapy can alleviate pulmonary inflammation without impairing anti-tumor effects.1426 Therefore, H2 gas can be adopted as adjuvant therapy to suppress these symptoms.
Chemotherapy, targeted therapy, and immunotherapy are first-line treatments against advanced NSCLC.272829 The vastly increased generation of reactive oxygen species during treatment is believed to contribute to adverse events, resulting in oxidative stress, inflammation and apoptosis.3031 In the present study, H2 therapy was shown to alleviate drug-related adverse events, most of which have been reported in animal models, including lung injury caused by various factors,18192021 hepatobiliary diseases,323334 maculopapular rash,35 diarrhea and constipation,363738 nausea and vomiting,3940 oral mucositis,4142 anemia,43 thrombocytopenia,44 and anorexia.45 We found that the prevalence of insomnia, dizziness and headache could be reduced significantly after H2 inhalation, which could be related to relief of diseases of the central nervous system, such as cerebral hemorrhage,464748 Parkinson’s disease4950 and Alzheimer’s disease,5152 observed in animal experiments. The mechanism of action observed in animal experiments could be used as a reference for clinical research. Surprisingly, H2 therapy, which is non-toxic and can alleviate adverse events in multiple organs simultaneously, has been used rarely.
We found that H2 monotherapy could prolong the PFS of patients with advanced NSCLC from 4.4 ± 1.2 months to 7.9 ± 2.2 months, suggesting that H2 could inhibit the growth of lung cancer cells independently. This hypothesis has been bolstered by data from an in vitro and in vivo study, which confirmed that H2 can inhibit the proliferation, migration, and invasion of the lung-cancer cell lines and tumor growth in mouse model.53 These data suggested that H2 could serve as new therapy against lung cancer. However, for patients eligible for first-line treatment, drugs will produce more pronounced effects upon tumor control. Whether a combination of drug therapy and H2 therapy can elicit better tumor control must be studied further, but gradual reduction of most drug-associated adverse events after H2 inhalation is clear.
Several delivery methods of molecular H2 are available and convenient: inhalation, drinking H2-dissolved water, injection with H2-saturated saline, and taking a “H2 bath.”54 H2 is non-toxic, inexpensive, can be administered readily, can diffuse into tissues and cells55 and cross the blood–brain barrier.56 Hence, H2 could be used to treat tumors of the head, neck and chest. Because of the risk of explosion of H2 and oxygen mixed in air, often such gas mixtures are inhaled using catheters and masks whereas, in animal experiments, drinking or injection of H2-dissolved water is employed. Use of a machine with a sufficiently high flow rate (3 L/min) and inhalation duration every day (4–6 hours) of H2 in this trial may enable control of tumor growth and reduce the prevalence of adverse events of drugs.
In general, H2 inhalation was first discovered in the clinic that can be used to control tumor progression and alleviate the adverse events of medications in patients with advanced NSCLC. The main limitation of this study is that the number of patients enrolled is relatively small, and more accurate patient benefits are still awaiting the results of large samples. Whether this therapeutic effect can be improved further, as well as determination of the synergistic effect of drugs and H2 therapy, must be explored further.

HBS10 is a device for hydrogen water and hydrogen breathing, with which everyone can easily apply hydrogen therapy at home. The device produces a minimum of 450 milliliters of gas per minute. This covers the internationally accepted standards for hydrogen inhalation therapy.
Proudly made in EU based on more than 10 years of experience in the production and development of hydrogen technologies
Chromatographically studied at Academy of Science CE certified Tested and Recommended by H2HUBB, USA
H2 therapy helps with all types of cancer. Hydrogen acts in two ways:
1. Hydrogen activates the Autophagy process in the body – thanks to hydrogen, the body begins to rid itself of cancer cells. 2. Hydrogen prevents the formation of new cancer cells. Free radicals in the body are the main factor that causes cancer cells to form. Hydrogen binds to free radicals and turns them into water molecules that are expelled from the body through the excretory system.
What other diseases does hydrogen therapy help with?
Hydrogen is the strongest antioxidant. It helps as an additional therapy for Asthma, COPD, Diabetes, Arthritis and any inflammatory processes in the body. It boosts metabolism and strengthens the immune system.
How is hydrogen therapy performed?
Hydrogen therapy is carried out by two methods – by inhalation with hydrogen gas, by inhaling with a mask or nasal cannula, or by drinking water saturated with hydrogen. Hydrogen inhalation is much more effective than hydrogen water. We recommend, whenever possible, to do inhalations for 30 minutes and during the rest of the time to drink water saturated with hydrogen.
How often should inhalation be done in people with oncological diseases?
We recommend, if possible, to breathe hydrogen for 30 minutes every 3 hours. In 30 minutes, hydrogen reaches all the organs in the human body. Over the next 3 hours or so, the hydrogen is exhaled or expelled from the excretory system. Inhalations should be made, for example, at 7:00, 10:00, 13:00, etc. until the end of the day.
When should we expect an improvement in the condition of a cancer patient?
After 22 to 50 days, tumor markers change.
Can a patient with stage 4 cancer get better?
Yes, unequivocally, hydrogen therapy improves the patient’s quality of life.
Can hydrogen therapy be used during chemotherapy, radiotherapy or targeted therapy?
Yes. It is recommended that, when conducting conventional therapies, hydrogen therapy should also be conducted in order to reduce the side effects of the drugs and to recover the patient faster.
