Study type
Interventional
Description of intervention(s) / exposure
Randomly selected patients who require breast conservation surgery and who have consented will be entered into the study. Patient numbers will be drawn from a box in theatre and this number will dictate either routine current surgical technique of wide local excision (control) or breast reshaping. In the breast reshaping, the breast tissue is mobilised superficially and deep from the skin and the pectoral muscles, respectively in order to close the defect (2/0 vicryl). Subsequently, deep dermal (2/0 vicryl) and skin sutures (3/0 monocryl subcuticular) are used to close the wound. The technique takes <30minutes. The wounds will be infiltrated with Bupivacaine local anaesthetic at a dose <2.0 mg/kg.
Intervention code [1] 284762 0
Treatment: Surgery
Comparator / control treatment
In the routine technique (control), deep dermal (2/0 vicryl) and skin stitches (3/0 monocryl subcuticular) are used to close the wound without attempting to close the defect in the breast tissue. The technique takes <30minutes.
Control group
Active

Outcomes
Primary outcome [1] 287033 0
Subjective assessment of cosmesis on a scale of 0 to 10.
Independent assessment by a panel (consists of two trained observers) and by the patient. There will be a live and a photographic assessment of the photograph taken on the previous outpatient visit. There will be an independent assessment for the breast size, breast shape and overall cosmesis using the following scale :

- Good cosmesis (7-8) : slight difference
- Fair (5-6) : obvious diffference but no major deformity
- Poor (4 or less) : major distortion of the treated breast

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
All patients under an identified Breast Surgeon's care who require breast conservation surgery will be asked to join the trial. The study will be discussed with them in detail and a patient information sheet will be provided. Patients will be asked to sign a separate consent form to participate in the study. Patients who agree to participate in the trial will be randomised to either having breast reshaping or the routine surgical technique (control) as disscused before. A sealed envelope containing a number is drawn from a box in theatre and this number will dictate either routine current surgical technique of wide local excision (control) or breast reshaping.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A simple randomisation performed by using a sealed envelope containing a number is drawn from a box in theatre and this number will dictate either routine current surgical technique of wide local excision (control) or breast reshaping.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?



Intervention assignment
Parallel
Other design features
The procedure of breast reshaping will be timed. Patients will then have axillary surgery according to the recognised unit’s protocol. In both groups, the wounds will be infiltrated with Bupivacaine (<2.0 mg/kg). Patients will be discharged home as appropriate.

All patients will be seen in the outpatient clinic at two weeks postoperatively and thereafter at three months, and every 6 months for three years for both oncological and cosmetic follow up. The oncology treatment and further follow-up will be according to the unit’s protocol and details of radiotherapy and all adjuvant treatment will be recorded.
