- Brief Summary
This study will examine whether lymphedema after breast cancer surgery can be reduced. In a randomised controlled design the aim is to investigate whether an early intervention with progressive resistance training and close monitoring of arm swelling can reduce the incidence of lymphedema after breast cancer surgery.
- Detailed Description
Lymphedema is a well known and much dreaded complication after breast cancer surgery. The aim in this study is to examine if lymphedema can be prevented with early progressive strength training focusing on the arm, and close monitoring of pre clinical lymphedema in the 1 year exercise period. The primary outcome is lymphedema, and secondary outcomes are pain, self-reported symptoms of swelling, sensory disturbance, physical and psychological functioning, fatigue, depression, anxiety and health related quality of life.
158 patients operated for breast cancer with axillary node dissection, will be invited from three hospitals in Denmark, Sealand (Rigshospitalet, Ringsted Hospital, and Herlev Hospital), while on the surgical wards. Two weeks later upon consent they are recruited, baseline tested and randomized to either exercise intervention or usual care control.
The exercise intervention consists of progressive resistance training, combined with a stretching programme, with a total duration of 60 minutes per session. The group attend supervised exercises twice a week and a once weekly home exercise programme of 45 to 60 minutes duration. After 20 weeks, exercises are converted to home exercises, and they are monitored by a weekly sms-service. At 12 months, follow-up measurements are taken for both groups. Lymphedema is defined as 3% limb volume change from the baseline measurement.

Group Intervention Description exercise group exercise The first 20 weeks, twice-weekly 60 minute session of physical exercise supervised by the research assistant and once weekly home exercise programme is offered. The exercise intervention will consist of stretching, scar tissue mobilization and resistance exercises. For the following 32 weeks a home-training manual specifying three times weekly training is provided. At week 26 an individual booster session will be offered. In the case of lymphedema, referral to trained lymphedema physiotherapist for evaluation of appropriate intervention is made.
- Primary Outcome Measures
Name Time Method Number of participants with Lymphedema measured by water displacement measurement 12 months Lymphedema is defined as \>3% increase in inter limb volume difference compared to baseline, measured by ml. water displaced by lowering arm into a tub of water.
- Secondary Outcome Measures
Name Time Method shoulder/arm/leg strength 12 months change from baseline in Newtons in hand held dynometry and in 7RM tests for dynamic muscle strength.
neuropathic pain 12 months Measured by questionnaire assessment on neuropathic pain scale (NeuPPS).
Self-reported, Functional Assessment of Chronic Illness Therapy-Fatigue (FACIT-fatigue) questionnaire. 12 months change from baseline in score on the FACIT-fatigue questionnaire
patient reported pain 12 months Pain through the study period measured on a pain scale developed to assess pain after breast cancer surgery by Gärtner et al (JAMA. 2009;302(18):1985-1992)
health related quality of life questionnaire 12 months Change from baseline in Health-related quality of life Self-report, The European Organisation for Research and Treatment of Cancer (EORTC QLQ C30), breast cancer specific module (BR 23).
International Physical Activity Questionnaire (IPAQ) baseline and 12 months Change in physical activity from baseline on the IPAQ
tissue composition by Dual Energy X-ray Apsorptiometry (DXA) 12 months Change from baseline in tissue composition of bone mass, lean mass and fat mass, both regional and overall, assessed by Dual Energy X-ray absorptiometry (DXA).
