Hyperbaric oxygen (HBO) therapy is a treatment where patients breathe 100% oxygen inside a pressurized chamber.(typically 1.5–3.0 ATA) This approach increases the oxygen concentration in the blood and tissues.Its strongest evidence base is: -Radiation enhancement (oxygen fixation) -Treatment of radiation necrosis -Wound healing in oncology patientsEnhanced Oxygenation of Tumors: -Many tumors are hypoxic (low in oxygen), which can make them more resistant to radiation and some forms of chemotherapy. Enhanced oxygenation through HBO may help overcome this hypoxia. Increased oxygen levels can lead to the formation of reactive oxygen species (ROS), which may damage cancer cells and sensitize them to treatment. Synergistic Effects with Radiation Therapy: -Oxygen acts as a radiosensitizer. Radiation-induced DNA damage can be more effective in the presence of oxygen, potentially improving the efficacy of radiotherapy. Some studies have explored combining HBO with radiotherapy to overcome radioresistance in hypoxic tumor regions. Improved Delivery of Chemotherapeutic Agents: -Elevated tissue oxygenation might enhance the delivery and efficacy of certain chemotherapeutic drugs, although this area is still under investigation. Potential Immune Modulation: -There is ongoing research into whether HBO can modulate the tumor microenvironment in a way that is more favorable for anti-tumor immune responses. Possible problems: -Implanted device (such as an insulin pump or pacemaker) -Avoid with recent perforated ear drum -Pneumothorax -Wait for 4 wks after chemo?

| Tumor Microenvironment: Cancer cells often thrive in a more acidic environment compared to normal cells. This is partly due to the metabolic processes of cancer cells, which can produce lactic acid and other acidic byproducts. The acidic microenvironment can promote tumor growth and invasion. Many tumors exhibit an acidic microenvironment. This is largely due to the high rate of glycolysis (often referred to as the Warburg effect), even in the presence of oxygen, leading to lactate production. Acidification is thought to promote invasion, metastasis, and resistance to certain chemotherapies. The body maintains a relatively stable pH in the blood (around 7.4). However, the pH of tissues can vary, and tumors can exhibit a lower pH. -Normal tissues have a higher extracellular pH than intracellular pH, in cancer is exactly the opposite. (inversion of the pH gradient). Cancer cells often overexpress proton pumps (such as V-ATPase) and transporters that actively extrude protons (H⁺) to maintain an intracellular pH conducive to their growth. Inhibiting these pumps can lead to intracellular acidification and potentially induce apoptosis or render cancer cells more vulnerable to other treatments. Normal pH levels in the body: Nasal: ~6.3 pH Mouth/saliva: 6.2-7.6 pH Stomach: 1-3 pH Small Intestine: 5.9-6.8 pH Colon/Large Intestine: 6.8-7 pH |
