Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
1 hour long individual face to face treatment sessions will be completed twice per week for 3 weeks (6 sessions in total) at the Westmead Hospital Breast Cancer Institute. Treatment includes Manual lymphatic drainage which is a technique performed by a trained lymphoedema therapist to move fluid from the swollen area (breast/arm area) to an area that has normal lymphatic drainage. It involves the therapist applying very gentle pressure to the skin in slow rhythmic movements. Participants will also receive verbal and written instruction on caring for their skin (using moisturiser) and be provided with 2 compression bras to wear 12 hours daily for 3 weeks (Bellisse bra - Jobst). Women will be asked to complete a daily diary of how long they wore the bra for and any issues with comfort.

Comparator / control treatment
Waitlist control group - Skin care and wearing of supportive bra for 21 days.
Women in the waitlist control group will commence intervention through a lymphoedema clinic/therapist of their choice following the final measures for the trial (i.e 3 weeks after the baseline measures).

Outcomes
Primary outcome [1] 322740 0
Change in patient reported outcome measures (composite primary outcome).
Four patient reported questionnaires will be completed to ensure all symptoms/experiences of breast oedema are examined:
- European Organisation for Research and Treatment of Cancer Breast (EORTC) QLQ-BR23
- Lymphoedema Symptom Intensity and Distress Survey –midline (LSIDS-M)
- Breast Oedema Bother Scale (BOB).
- Breast Lymphoedema Severity Symptom (BLYSS) questionnaire
Timepoint [1] 322740 0
Baseline and end of treatment (3 weeks)
Those in the treatment arm will also be asked to complete the questionnaires at each treatment visit to assess for any fluctuations in symptoms with treatment.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation will occur after the baseline measures are completed by a person not involved with the project who will prepare sequentially numbered opaque envelopes with the group allocation sealed inside.
.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The randomisation list will be computer generated by a person not involved with the project following the baseline measurements

Efficacy
Statistical methods / analysis
For the primary aim (PROM change), with two groups of 20 patients in each group (40 patients in total), there is a 80% power of detecting a statistically significant difference between the treatment arm and the non treatment arm with an effect size of 0.74 using a 5% significance level (2 sided t test). We will comparing change at baseline and end of treat and between the intervention and non intervention arms accounting for 10% drop out.
• Null hypothesis:
Change in PROM in non intervention group = Change in the intervention group
• Alternative hypothesis:
Change in PROM in non intervention group does not equal Change in the intervention group
Statistical Analysis Plan
Primary Outcome:
The 2 sided t test (5% significance level) will be used to analyse the primary outcome of PROM change.
Secondary Outcomes:
Spearman rank correlations will be used to look at associations between MRI and the other measurement techniques. Logistic regression analysis will be used for the patient report outcome measures and determing the strength of association in any of the scales.
Changes will be analysed using descriptive analysis including means/standard deviations or median and interquartile range. Data extracted from the different imaging approaches will be compared using paired t-tests and 95% confidence intervals if data are normally distributed otherwise using non-parametric methods.
