NCT01659723

Brief Summary

The primary objective of this study is to assess the relief of symptoms after Hyperbaric Oxygen Therapy (HBOT) in patients with late radiation cystitis by having Expanded Prostate cancer Index Composite (EPIC)symptom estimation scale as primary variable. Study hypothesis:

  • HBOT can reduce or reverse the change or otherwise limit the damage of the bladder function and/or structure, which arose as a result of radiation therapy of cancer in the pelvic region organs.
  • The effects of HBOT are associated with relief of symptoms that, at least in part, is related to the reduction of the extent of the radiation damage.
  • Vascular density increases, fibrosis prevalence and inflammatory activity are reduced as a sign of an improved function of the mucosa.
  • Treatment results of HBOT remains, in whole or in part, during the follow-up (residual effect)

Outcome Measures

Primary Outcomes (1)

  • EPIC (Expanded Prostate cancer Index Composite)

    EPIC was developed to measure health-related quality of life among men with prostate cancer (22) modified to enhance sensitivity to therapy effects. It comprises four summary domains; urinary, bowel, sexual and hormonal. The primary objective of this study is to assess the relief of symptoms after HBOT in patients with late radiation cystitis by having EPIC symptom estimation scale as primary variable, comparing results between group A (post treatment) and group B (pre treatment). All patients (Group A and B) will complete EPIC and SF-36 in a post-study long-term follow-up. This is done yearly for 5 years (18, 30, 42, 54 and 66 months post inclusion).

    At inclusion, 6 months after inclusion (i.e. post treatment for group A and pre treatment for group B) and for long-term follow-up as specified under "description"

Secondary Outcomes (4)

  • Microscopic assessment

    At inclusion and 6 months after inclusion (i.e. post treatment for group A and pre treatment for group B)

  • RTOG (Radiation Toxicity Grade by Radiation Therapy Oncology Group)

    At inclusion and 6 months after inclusion (i.e. post treatment for group A and pre treatment for group B)

  • SF-36 (Short Form Health Survey 36)

    At inclusion, 6 months after inclusion (i.e. post treatment for group A and pre treatment for group B) and for long-term follow-up as specified under "description"

  • Adverse events

    Every day during HBOT (8 weeks).

Study Arms (2)

A - Immediate start

ACTIVE COMPARATOR

Start of treatment within 6 weeks of inclusion in the study. 100% oxygen at 240-250 kPa will be delivered to the patents for 80-90 minutes while sitting or lying in a hyperbaric oxygen chamber. Patients will receive treatment once every day, except week-ends, for 40 days.

Drug: Hyperbaric Oxygen

B - delayed start

NO INTERVENTION

Delayed start: Start of treatment not before 6 months of inclusion in the study. No intervention is given during the initial period.

Interventions

100% oxygen at 240-250 kPa will be delivered to the patents for 80-90 minutes while sitting or lying in a hyperbaric oxygen chamber. Patients will receive treatment once every day, except week-ends, for 40 days.

A - Immediate start
