Abstract
Background: Weight loss can improve breast cancer related lymphoedema [BCRL]
(Shaw et al. [1]), but is not routinely advised in clinical practice which just involves
standard arm mobility exercises. We are determining whether supervised or home based
diet and exercise weight loss programmes are effective for reducing weight and
lymphoedema in a feasibility study This abstract presents preliminary data on compliance
to the weight loss interventions.
Aims: To evaluate change in weight, body fat, waist circumference, dietary intake and
physical activity in breast cancer survivors’ with lymphoedema who were randomised to
either a 12 week supervised or home based diet and exercise weight loss programme or
two comparison groups.Methods: Ethical approval was granted by North West 10 Research Ethics Committee –
Greater Manchester North 11/H1011/2 .Fifty seven overweight breast cancer survivors’
with lymphoedema were randomly assigned: Supervised group, diet and exercise weight
loss advice delivered during weekly sessions at the research facility (n= 12); Home- based
group, diet and exercise weight loss advice via fortnightly phone calls and tailored mailings
(n=16); Comparison group 1, arm mobility and standard written weight loss advice group
(n=12); Comparison group 2, arm mobility advice only group who did not receive any
weight loss advice (n= 17).
Data Analysis: Weight and body fat, measured via DXA and waist circumference were
assessed at baseline and 12 weeks. Seven day diet and physical activity diaries were
analysed for changes in energy intake and cardiovascular activity. Changes in variables
apply last observation carried forward analysis. There were no planned statistical analyses
in this feasibility study.
Results: Four participants from the home- based diet + exercise group and four from
comparison group 2 dropped out of the study.
The supervised and home based groups had numerically greater reductions in body
weight and body fat than the comparison groups. Changes in body fat and waist
circumference represent real reductions in general and central adiposity, which are
independent of any changes in weight and body water which may occur in patients with
lymphoedema.
Discussion: The successful reductions in body weight and fat with the two lifestyle
interventions show it is possible to reduce adiposity in overweight women with BCRL.
Conclusion: Further analysis from this pilot trial will assess changes in lymphoedema
between the groups. The longer term adherence and success of the home based and
supervised interventions would need to be tested in a larger randomised trial.
