Study information

Scientific title

Support, Positioning and Organ stabilisation during Breast Cancer Radiation Therapy: The SuPPORT 4 All project



Study hypothesis

The aim of this study is to test how practical it is for women to wear the S4A bra during radiotherapy, and how easy it is for the radiographers to use the bra to help them position the patient underneath the radiotherapy machine each day.

Specialty: Cancer, Primary sub-specialty: Breast Cancer; UKCRC code/ Disease: Cancer/ Malignant neoplasm of breast


Patients will be randomised 1:1 to one of two groups. Randomisation will be through block randomisation (with blocks an integer multiple of four); stratified by breast/bra cup size (S4A bra size 3-7 vs. S4A bra size 8-12). The trial statistician will generate a randomisation schedule using existing software. This will be held remotely by the study-co-ordinator (who will not be directly involved in recruiting patients to the study).

Intervention group: Participants receive breast radiotherapy with S4A bra with one tattoo. This involves standard radiotherapy to the breast with patients planned and treated in the S4A bra with a single anterior permanent tattoo placed on the midline according to normal practice for breast irradiation. Patients will receive a standard radiotherapy dose of 40Gy in 15 fractions (daily over three weeks).

Control group: Participants receive their existing radiotherapy with standard set-up with no immobilisation with tattoos. This involves patients being planned for breast irradiation and treated as per standard practice with three permanent tattoos place on the torso one anteriorly on the midline and one either side of the thorax. Patients in the control group will be treated to the standard radiotherapy dose of 40Gy in 15 fractions (daily over three weeks).

Follow up involves completion of a postal questionnaire at 7 weeks (body image questionnaire, skin and breast changes self assessment, and patient empowerment questionnaire) and a final postal questionnaire at 3 months to assess body image. (details of other outcomes measured during treatment are listed in the outcome section).

Intervention type



Drug names

Primary outcome measure

Feasibility of recruitment to main trial is defined as recruitment of 50 participants recruited in a six-month recruitment window at one centre.

Secondary outcome measures

Secondary feasibility outcomes
1. Recruitment and attrition rates (CONSORT data): number of patients assessed for eligibility; reasons for exclusion, numbers discontinuing intervention (with reasons), numbers analysed and excluded from the analysis
2. Number of missing values/incomplete cases is measured by reviewing study data at endline
3. Intervention adherence: Defined objectively as the number of radiotherapy fractions where the bra is used (for the intervention group) divided by the number of fractions prescribed
4. Intervention fidelity: During the study period site observations will be undertaken of treatment set-up for patients in both the control and intervention arms to ensure the support bra is used and positioned correctly and technique protocols are used in a standard manner across intervention and control groups
5. Technology acceptance from both healthcare practitioners and patients using an adapted Technology Acceptance Tool (based on the Technology Acceptance Model) at baseline
6. Feasibility of recruiting future participating centres: target sites for the main study will be screened for suitability, by interviewing potential principal investigators

The following outcome measures will be assessed for suitability to be used in the main trial:
1. Skin reactions using the Radiation Therapy and Oncology Group skin scoring assessment (RTOG) both staff scored and patient self –reported using a new lay reporting skin assessment tool. Measured at baseline and weekly while on treatment then at four weeks post treatment.
2. Dose to organs at risk, including mean ipsilateral lung dose, and mean heart dose (for those treated for a left breast cancer) measured from the radiotherapy treatment plan
3. Incidence of moist desquamation in the inframammary fold at week 3 of radiotherapy
4. Patient comfort measured by a comfort questionnaire developed from interviews with healthy volunteers that have tried the support bra and adaptations of the Kolcaba patient comfort questionnaire for radiotherapy patients, measured at baseline (at the time of fitting during radiotherapy planning) and weeks 1, 2 and 3 of treatment
5. Patient modesty measured by the patient modesty scale and a newly developed story board of the radiotherapy journey to measure patient experiences of physical exposure at weeks 1, and 3 of treatment
6. Patient empowerment using the 28-item patient empowerment scale for cancer patients, measured at baseline and weeks 1, 2, 3 and 7 of radiotherapy
7. • Body Image using the 10-item body image scale, measured at baseline and at 3 weeks, week 7 (one month post treatment) and 3 months
