Summary
Brief summary
The principle objective of this research is to more precisely determine the degree of benefit
that hyperbaric oxygen therapy affords in the treatment of late radiation tissue injury.

The study has eight* components. Seven involve the evaluation of established radionecrosis at
varying anatomic sites (mandible, larynx, skin, bladder, rectum, colon, and gyn). The eighth
will investigate the potential of hyperbaric oxygen (HBO) therapy to prophylax against late
radiation tissue injury.

*(One of the arms, HORTIS IV - Proctitis has been closed to further patient recruitment. This
decision was based on an interim statistical analysis which generated sufficient evidence to
support closing down this arm of HORTIS.)
