Scientific title	Randomised phase II trial of Hyperbaric Oxygen Therapy in patients with chronic arm lymphoedema after radiotherapy for early breast cancer
Study acronym	HOT
Study hypothesis	Added 06/08/09: The primary aim is to test the efficacy of hyperbaric oxygen (HBO) therapy in reducing arm lymphoedema in patients suffering long-term adverse effects of high dose radiotherapy for early breast cancer. The secondary aim is to test mechanisms of tissue reperfusion and healing in response to hyperbaric oxygen (HBO) therapy. As of 06/08/09 this record has been extensively updated. All updates can be found under the relevant field with the above update date.
Ethics approval(s)	Not provided at time of registration
Condition	Chronic radiation-induced arm lymphoedema.
Intervention	Treatment group: Patients are compressed to 2.4 Atmospheres Absolute (ATA) while sitting in a multiplace hyperbaric chamber. Patients breathe 100% oxygen at pressure via a transparent hood. The total time at 2.4 ATA is 90 minutes. Each participant will receive a total of 30 pressure exposures (5 days per week for 6 weeks). Control group: Patients continue treatment according to best standard management as defined by the trial protocol.
Intervention type	Other
Primary outcome measure	Added 06/08/09: Volume of the affected limb, expressed as a percentage of the contralateral limb Volume on the day of measurement, as measured by perometer 12 months after baseline assessment
Secondary outcome measures	Added 06/08/09: 1. Patient self-assessments, using specific quality of life scale in upper limb lymphoedema and the UK SF-36 Health Survey Questionnaire, at 3, 6, 9 and 12 months after baseline assessment 2. 99Tc-nanocolloid clearance rate as measured by quantitative lymphoscintigraphy 12 months after baseline assessment 3. Extracellular water content as measured by EdemaMeter (bioimpedance measurements) 12 months after baseline assessment
Overall study start date	01/01/2006
Overall study end date	31/12/2008
