RATIONALE: Radiation therapy can cause long-term adverse effects. Hyperbaric oxygen therapy may be effective in lessening gastrointestinal symptoms caused by radiation therapy given for pelvic cancer. It is not yet known whether high-pressure oxygen is effective in treating adverse effects caused by radiation therapy.
PURPOSE: This randomized phase III trial is studying hyperbaric oxygen therapy to see how well it works in treating long-term gastrointestinal adverse effects caused by radiation therapy in patients with pelvic cancer.
Further Study Information
- To determine the clinical benefits of hyperbaric oxygen therapy in reducing dysfunction in patients with pelvic cancer developing iatrogenic gastrointestinal symptoms as a result of previous radical pelvic radiotherapy completed at least one year ago.
OUTLINE: This is a multicenter study. Patients are stratified according to center and severity of symptoms (low vs high). Patients are randomized to 1 of 2 treatment arms.
- Arm I (treatment group): Patients undergo hyperbaric oxygen therapy over 90 minutes, 5 days a week, for 8 weeks for a total of 40 treatments. Oxygen at 100% is breathed for 30 minutes, followed by a 5-minute "air break" and a further 30 minutes of breathing oxygen. A further 5-minute "air break" is followed by a further 30 minutes of breathing oxygen. During the final 10 minutes of oxygen breathing, the chamber is depressurized to ambient atmospheric pressure at a linear rate (14.2 kPa/min).
- Arm II (control group): Patients undergo hyperbaric oxygen therapy over 90 minutes, 5 days a week, for 8 weeks for a total of 40 treatments. Oxygen at 21% is breathed for 30 minutes, followed by a 5-minute "air break" and a further 30 minutes of breathing oxygen. A further 5-minute "air break" is followed by a further 30 minutes of breathing oxygen. During the final 10 minutes of oxygen breathing, the chamber is depressurized to ambient atmospheric pressure at a linear rate (3 kPa/min).
Tissue samples from rectal biopsies may be collected and analyzed.
Patients complete questionnaires (Health Economics, Inflammatory Bowel Disease Questionnaire [IBDQ], EORTC Quality of Life [QLQ]-C30, and QLQ-CR38) at baseline and then at 3, 6, 9, and 12 months after the start of treatment.
After completion of study treatment, patients are followed within 14 days and at 10 months.
- Past history of rectal, prostate, testicular, bladder, uterine cervix, uterine corpus, vaginal, or ovarian cancer
- Malignant disease (T1-3, N0-1, M0)

- Grade 1 with difficult intermittent symptoms
- Symptoms are not relieved by appropriate life-style advice and medication over a 3-month period
- Must be physically and psychologically fit to undergo hyperbaric oxygen therapy

- No contraindication or other inability to undergo magnetic resonance imaging, if required to rule out malignancy
PRIOR CONCURRENT THERAPY:
- See Disease Characteristics
- No prior surgery for rectal cancer
- No prior hyperbaric oxygen therapy (excluding treatment for decompression illness)
- No prior treatment with bleomycin
