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.
