E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
We investigate if women who have developed lymphoedema 1 year after surgery for breast ancer benefit from Hyperbaric Oxygen Treatment (HBOT) in terms of reduction of the arm volume.
|
Vi undersøger om kvinder der har udviklet lymfødem et år efter operation for brystkræft kan have gavn af Hyperbar oxygen terapi for at reducere arm volumen. |
|
E.2.2 | Secondary objectives of the trial |
To examine if HBOT can increase the lymphatic clearance rate measured by lymphoscintigraphy, as well as psychological and physical function. |
At undersøge om Hyperbar Oxygen terapi jan forbedre lymfatisk drænage evne målt ved lymfesintigrafi, samt om det kan forbedre psykisk og fysisk funktion. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Participants in LYCA EXERCISE with lymphoedema 12 months after surgery for breast cancer will be invited to participate. Lymphedema is present if a swelling of the arm on the operated side has persisted more than 4 weeks with a combined score of 2 points or more on NRS for symptoms, and a clinical exam reveals 2 or more of the following criteria to be present (i-iii are compared with the unaffected side):
i. decreased visibility of subcutaneous veins on the ventral lower arm or dorsal hand
ii. loss of normal contours in the region of the medial side of the elbow/distal end of the upper arm
iii. thicker skin and subcutis on palpation
iv. pitting oedema
They must also be declared cancer free (before clinical mammography) |
Participants with lymphoedema 12 months after surgery for breast cancer will be invited to participate. Lymfødem er tilstede hvis en hævelse af armen i opererede side har varet i mere end 4 uiger med en kombineret score på mere end 2 på NRS for symptomer, og en klinisk undersøgelse afdækker 2 elelr flere af nedenstående kriterier som opfyldt: (i-iii sammenlignes med modsatte side):
i. nedsat synlighed af subkutane vener på ventrale underarm eller dorsum af hånden
ii. tab af normale konturer i mediale side af albue regionen/distale ende af overam
iii. tykkere hud og subkutis ved palpation
iv. pitting ødem
I øvrigt skal de være erklæret cancer fri (inden klinisk mammografi) |
|
E.4 | Principal exclusion criteria |

pregnancy
untreated severe heart failure detected during pre-examination for HBOT
Undrained pneumothorax
Unability to equalize pressure in the ears in spite of drain treatment by Ear- Nose- and Throat specialist.

Fuldført kemoterapi og/eller stråleterapi mindre end 4 uger siden
graviditet
ubehandlet svær hjertesvigt fundet ved forundersøgelse til HBOT
udrænet pneumothorax
ude af stand til at trykudligne i ørene trods drænanlæggelse ved øre-næse-hals specialist
Klaustrofobi som ikke responderer til på normal pre-medicinering. |
