About Carbogen therapy and oxidative stress in cancer treatment

Introduction to Carbogen and CO₂ therapy

Carbogen therapy, a mixture of 95% oxygen and 5% carbon dioxide (CO₂), is a therapeutic method that promotes oxygen delivery to tissues by utilizing the Bohr effect. This process means that CO₂ reduces hemoglobin's affinity for oxygen, allowing oxygen to be released more efficiently to tissues. This is especially useful in tissues with low oxygen saturation, such as tumors and damaged tissue.

Carbogen is often used in combination with other cancer treatments such as radiation therapy, where it increases the oxygen content in cancer cells, thereby improving treatment outcomes. At the same time, pure CO₂ inhalation therapy has been shown to improve oxygen utilization at the cellular level by stimulating deeper breathing and improving blood flow. Carbogen can be used together with a range of other anticancer therapies when the goal is to achieve the best possible tissue oxygen saturation. Combinations with HBOT, etc. may be relevant.

Physiological benefits of Carbogen therapy

1. Improved oxygen delivery via the Bohr effect: Increased CO₂ leads to a shift in the oxygen-hemoglobin dissociation curve, resulting in increased oxygen delivery to areas with low oxygen supply, such as hypoxic tumors or damaged tissue. This can be crucial in the treatment of serious diseases such as cancer and stroke, where oxygen is a key factor in tissue healing and combating cell damage.
   
   
2. Improved blood circulation: CO₂ promotes dilation of the blood vessels (vasodilation), which improves blood circulation in areas with reduced blood flow, for example in conditions such as chronic obstructive pulmonary disease (COPD), ischemia, and sudden hearing loss. This increases oxygen saturation in cells and tissues suffering from oxygen deficiency.
   
   
3. Neurological and respiratory benefits:
• Neurological protection: Increased cerebral blood flow as a result of carbogen therapy may have neuroprotective effects in conditions such as stroke and traumatic brain injuries. This helps reduce damage and support tissue recovery.
• Respiratory improvement: In conditions such as COPD and asthma, carbogen stimulates deeper breathing, improves oxygen uptake, and reduces shortness of breath.
  
  
4. Adjuvant in cancer treatment: Carbogen therapy is often used in combination with radiation therapy. Tumors that thrive in hypoxic environments are usually more resistant to radiation. By improving oxygen saturation with carbogen therapy, the production of reactive oxygen species (ROS) is increased , making cancer cells less resistant during radiotherapy or other anticancer therapy that promotes the formation of ROS in cancer cells.

Protocols for Carbogen therapy

1. Sudden hearing loss:
• Protocol: 15-30 minutes, 2-3 times daily for 7-10 days.
• Mechanism: Increased blood flow to the inner ear helps regenerate damaged hair cells and may restore hearing.
  
  
2. Cancer treatment:
• Protocol: 5-10 minutes before each radiation treatment throughout the entire course of treatment.
• Mechanism: Increased oxygen supply to cancer cells improves the effect of radiation by increasing ROS production.
  
  
3. COPD and respiratory diseases:
• Protocol: 5-15 minutes once or twice daily, depending on the symptoms.
• Mechanism: Improved oxygen delivery and reduced shortness of breath by stimulating deeper breathing.
  
  
4. Neurological conditions (stroke, traumatic brain injuries):
• Protocol: 15-20 minutes daily for several weeks as part of a rehabilitation program.
• Mechanism: Increased oxygenation of the brain protects nerve cells and contributes to the restoration of damaged brain tissue.

Natural substances that promote oxidative stress in cancer cells

Several natural substances have been shown to either increase the production of ROS in cancer cells or weaken their antioxidant defenses, making them vulnerable to oxidative stress and cell death (apoptosis), including:

1. Curcumin:
• Source: Turmeric (Curcuma longa)
• Effect: Promotes ROS production and reduces glutathione levels, an important antioxidant in cancer cells.
  
  
2. Quercetin:
• Source: Onions, apples, berries, green tea
• Effect: Increases ROS levels and inhibits heat shock proteins that protect cancer cells.
  
  
3. EGCG (epigallocatechin gallate):
• Source: Green tea
• Effect: Promotes ROS production and reduces cancer cells’ ability to repair oxidative damage.
  
  
4. Resveratrol:
• Source: Red wine, grapes, berries
• Effect: Acts as a pro-oxidant in cancer cells and increases ROS, which promotes apoptosis.
  
  
5. High-dose vitamin C:
• Effect: Acts as a pro-oxidant by producing hydrogen peroxide (H₂O₂) in cancer cells, which lack catalase, unlike normal cells. This leads to ROS-induced cell death.
  If a sufficiently high dose is not used, vitamin C may have the opposite effect (protecting cancer cells against oxidation). Intravenous vitamin C will be the safest option, although it is possible to achieve high serum/tissue concentrations by using professional liposomal vitamin C products frequently, preferably in combination with vitamin C powder in water.
  
  
6. Sulforaphane:
• Source: Broccoli and cruciferous vegetables
• Effect: Promotes ROS and inhibits cancer cells’ ability to neutralize oxidative stress.
  
  
7. Thymoquinone:
• Source: Black seed oil (Nigella sativa)
• Effect: Increases ROS and reduces glutathione levels, leading to apoptosis.

Combination therapies involving oxidative stress

Carbogen therapy can be combined with other oxidative stress-inducing therapies to improve the effect:

1. Carbogen + radiation therapy: Increased oxygenation from carbogen improves radiation’s ability to generate ROS and damage cancer cells.
   
   
2. Carbogen + photodynamic therapy (PDT): Increased oxygen supply improves ROS production in photodynamic therapy, which increases the cancer cells’ sensitivity to light-activated cell death.
   
   
3. Nicotinamide + Carbogen: Nicotinamide inhibits cancer cells’ ability to repair DNA damage from ROS. The combination with carbogen makes tumors even more vulnerable.

Safety and contraindications

Carbogen and CO₂ therapies are safe when administered correctly, but should be monitored closely, especially for patients with respiratory problems or anxiety. Some individuals may experience discomfort with increased CO₂ levels. In home-based CO₂ -therapies, recommended protocols should be followed carefully.

Conclusion

Carbogen therapy, combined with oxidative stress-inducing treatments such as radiation, photodynamic therapy, and natural substances such as curcumin, nicotinamide, and high-dose vitamin C, represents an advanced approach to cancer treatment. By increasing oxygen levels in hypoxic tumors, Carbogen improves ROS production, making cancer cells more vulnerable to apoptosis. The combination of such treatments maximizes their effect and reduces damage to healthy cells. The above are examples and are not intended to constitute any treatment recommendation; all cancer treatment in Norway must and shall be carried out by an approved oncologist. 

When used correctly, these treatments can lead to improved clinical outcomes by preventing cancer cells from resisting oxidative stress. At the same time, natural pro-oxidants such as curcumin, quercetin, EGCG, and resveratrol can enhance the effects by increasing ROS levels in cancer cells, making them even more susceptible to apoptosis. Combination therapies such as these represent a promising path in cancer treatment.
