Understanding radiation damage to the abdomen and how oxygen therapy reverses it

Radiation therapy directed at abdominal and pelvic tumors saves lives but can cause significant collateral damage to healthy tissue. This includes enteritis (intestinal inflammation), proctitis (rectal inflammation), cystitis (bladder irritation), fibrosis (tissue scarring) and vascular injury. These radiation injuries can cause chronic pain, bleeding, diarrhea, urinary problems and difficulty controlling bowel function.

The damage occurs because radiation destroys blood vessel linings through obliterative endarteritis, creating tissue that becomes progressively hypovascular, hypoxic and hypocellular. These injuries can appear months to years after radiation treatment and worsen over time. HBOT directly reverses this damage by regrowing blood vessels, restoring oxygen delivery and regenerating healthy tissue in the affected organs. The FDA, AMA and Medicare approve HBOT for delayed radiation injuries.

  • Chronic abdominal pain, bleeding and diarrhea

  • Intestinal inflammation (enteritis) and rectal inflammation (proctitis)

  • Bladder irritation, urinary urgency and incontinence

  • Tissue scarring (fibrosis) and progressive organ dysfunction

Clinical evidence for HBOT in abdominal and pelvic radiation injuries

Hyperbaric oxygen therapy for delayed radiation injuries to the abdomen and pelvis is supported by extensive clinical evidence and approved by the FDA, AMA and Medicare.

Comprehensive evidence review: A 2021 bibliographic review (Fernandez et al.) evaluating HBOT for radiation-induced toxicities found Grade B and C evidence supporting its use across multiple abdominal and pelvic indications. HBOT demonstrated efficacy in reducing late-onset radiation injuries to the intestines, rectum, bladder and surrounding tissues.

Symptom and quality of life improvement: A large retrospective study in breast cancer patients with radiation-induced toxicities showed that HBOT significantly improves patient-reported pain scores (EQ-5D and NRS) and overall quality of life measures. These improvements were sustained beyond the treatment period.

Hemorrhagic cystitis: Studies demonstrate that over 50% of patients with radiation-induced hemorrhagic cystitis experience clinical benefit from HBOT, with complete or significant partial resolution of bladder bleeding and urinary symptoms.

Mechanism of action: Radiation damages abdominal tissue through obliterative endarteritis, creating a progressive cycle of hypovascularity, hypoxia and hypocellularity. HBOT reverses all three by stimulating angiogenesis (new blood vessel growth), delivering 1,200% more oxygen to hypoxic tissue and mobilizing stem cells for tissue regeneration. These mechanisms enable the intestines, rectum, bladder and surrounding tissue to regenerate.

Safety with cancer history: Over 50 years of research confirms that HBOT does not stimulate cancer cell growth or tumor recurrence. It is specifically designed to heal the collateral tissue damage caused by the radiation therapy used to fight cancer.

HBOT Demonstrates Efficacy in Mitigating Radiation-Induced Toxicities and Enhancing Radiotherapy Outcomes

This large study of consecutive breast cancer patients with late radiation toxicity shows a beneficial effect of HBOT on patient-reported symptoms and quality of life and functioning until at least three months after HBOT.

According to a bibliographic review, hyperbaric oxygen therapy (HBOT) has emerged as a promising treatment for managing radiation-induced toxicity and enhancing the efficacy of radiotherapy. Approximately 5% of cancer patients treated with radiotherapy experience severe late-onset toxicity. HBOT has been used for decades to treat radiation injuries, with data from small studies and case reports. The review found Grade B and C evidence that HBOT at pressures exceeding 2 absolute atmospheres (ata) can reduce late-onset radiation injuries to the head and neck, bone, prostate, and bladder, prevent osteoradionecrosis after exodontia in irradiated areas, increase the effectiveness of radiation in head and neck tumors, and achieve promising results in the local control of high-grade gliomas. This is likely due to HBOT's ability to increase oxygen tension in tissues, which could theoretically enhance the efficiency of radiotherapy. Overall, the findings suggest HBOT is a valuable tool for clinicians managing radiation-related complications and optimizing radiotherapy outcomes. Fernández, E., Morillo, V., Salvador, M. et al.

HBOT Improves Symptoms and Quality of Life in Breast Cancer Patients with Radiation-Induced Toxicities

We present the effect of hyperbaric oxygen therapy (HBOT) after radiotherapy for cancer in the pelvic cavity resulting in hematuria. Increasing the pressure of oxygen (PO2) in ischemic tissues favors the formation of new blood vessels and increases the secretion of collagen.

In a large retrospective analysis of over 1,000 breast cancer patients with late radiation toxicities, hyperbaric oxygen therapy (HBOT) was shown to significantly improve a range of clinical outcomes. After HBOT treatment, patients reported decreased pain scores, reduced breast and arm symptoms, and improved quality of life measures compared to baseline. The most common side effects were mild, including myopia and barotrauma, with only 3.2% experiencing moderate to severe effects. Factors associated with persistent breast pain after HBOT included active smoking during treatment and a shorter time (median 17.5 months) since completing radiotherapy. These findings demonstrate the efficacy of HBOT in mitigating the debilitating long-term effects of radiation therapy in breast cancer patients and support its use as a valuable management strategy for this patient population.

THE EFFICACY OF HYPERBARIC OXYGEN THERAPY IN THE TREATMENT OF RADIATION-INDUCED LATE SIDE EFFECTS

Our retrospective study indicates that HBOT seems to be an efficacious treatment modality for many radiation-induced late side effects.

In recent years, our understanding of the underlying mechanisms of late radiation-induced side effects has increased. Although cellular depletion and tissue devascularization were originally thought of as being the predominant pathologic basis for these side effects, they represent merely a histopathologic marker for a far more complex and clinically diverse problem
TESTIMONIALS

Radiation damage patients share their recovery stories

Lisa St John, the clinic director for Bay Area Hyperbarics, had chronic refractory osteomyelitis that lasted seven years with no relief. The infection induced severe fatigue and cognitive impairment that prevented her from working and required her to sleep up to 18 hours per day. Finally, a physician recommended hyperbaric oxygen therapy with antibiotics, which after 60 osteomyelitis treatments, healed her. Shortly after being healed, she sold her home to begin her first hyperbaric oxygen therapy clinic, which she has owned for 25 years!

Lisa, 44

Jennifer had osteomyelitis of the lower jaw (mandible), which proved difficult to heal. Her teeth were becoming loose, and her doctor thought she would need surgery. However, he prescribed hyperbaric oxygen therapy before the surgery, and after 60 osteomyelitis treatments, her chronic refractory osteomyelitis healed completely, regrowing bone in her mandible. Jennifer was able to keep her teeth, and was able to return to her active lifestyle, hiking regularly with her husband.
