Background and study aims
The results from Gene Expression Profiling (GEP) tests in breast cancer are used to determine whether additional chemotherapy has a role in reducing a patient’s risk of recurrence. Healthcare Professionals can find discussing GEP test results challenging and many breast cancer teams provide patients with information leaflets to aid their understanding of the tests. Unfortunately, these are often written by either academic or commercial sponsors and designed to meet certain ethical and regulatory guidelines and are often hard to understand by the public user.

Two gene expression profiling tests used in breast cancer in the UK are Oncotype DX and Prosigna. We examined the ease of readability of patient information leaflets describing these tests. Both employed complex language and concepts. We therefore designed 2 short (8 minute) patient information films, one for Oncotype DX and one for Prosigna. We compared the ability of these to convey basic information about GEP testing and recurrence risk results with that achieved after reading an information leaflet.

Results from the IMPARTER (Phase 3) cross-over study, showed that providing information about Oncotype DX or Prosigna in film format, significantly improved the knowledge of 120 women aged 45-75 (without breast cancer) compared with that achieved after reading the information leaflets. A majority of participants preferred the films for reasons including clarity, simple graphics, and reassuring tone and pace. The leaflets proved difficult for most participants to understand, often due to the medical terminology used, irrelevant extra information, and the layout.

IMPARTER Phase 4 takes place in a clinic setting with patients identified by their breast cancer multidisciplinary team as benefiting from having their tumour sample sent for GEP analysis. We wish to examine if providing a patient information film about either Oncotype DX or Prosigna, 1) improves the knowledge needed to inform decision-making, and 2) enhances satisfaction with patient–clinician discussions.

Who can participate?
Adult women over 18 years, who have had successful surgery to remove breast cancer.

What does the study involve?
Participants will be randomly allocated to receive standard information (usual practice/leaflets) plus or minus the patient information film.
Later their knowledge and understanding of GEP will be assessed.
The outcomes will show if the film provides additional value to patients over the standard information alone (usual practice/leaflet), in terms of knowledge and satisfaction with the consultation and decision-making.

What are the possible benefits and risks of participating?
There are no direct benefits in taking part. However, the study will show if the film is an additional useful source of information for patients considering GEP tests. This may help people with breast cancer in the future. The main disadvantage of taking part will be the time it takes to complete the assessments. Some people may feel uncomfortable answering questions about their understanding of GEP tests.

Scientific titleIMproving PAtient undeRstanding of GEP TEst Results: Phase 4
Study hypothesis1. Those patients viewing the information film will have higher GEP knowledge scores than those having standard information alone
2. Increased knowledge (and better understanding of recurrence risk results) is associated with less decisional conflict
3. The clinicians’ satisfaction with the risk results consultations will be higher in patients randomised to standard information plus film
Ethics approval(s)Approved 21/12/2021, London- Bromley Research Ethics Committee (Level 3, Block B, Whitefriars, Lewins Mead, Bristol, BS1 2NT, UK; +44 207 104 8105; bromley.rec@hra.nhs.uk), ref: 21/PR/1576
ConditionBreast cancer
InterventionThis is a randomised trial using quantitative methods. Participants will complete questionnaires and take part in a verbal knowledge assessment with a researcher in relation to GEP testing.

Patient online assessments
The research team will e-mail participants with a link to complete their online consent form, demographic questions, the STAI trait (20 items) and state inventories (20 items) and an intolerance of uncertainty measure (12 items).

The online STAI state inventory will be completed again, along with the Decisional Conflict Scale (10 items), within a week of a patient having their GEP test result consultation.

Patient randomisation
Once participants have completed their initial online assessments they will be randomised to groups - group A will not receive any additional information to that which they receive from their clinical team as per standard of care. Group B will be sent an additional link to watch a video on the GEP test they're having - either Oncotype DX or Prosigna. Group randomisation will be stratified by site.

Patient knowledge assessment
All participants will take part in a telephone interview prior to receiving their GEP results. This will comprise of knowledge items plus additional questions to gather feedback on what resources participants used, whether they sought advice from anyone else, what they liked and what they did not find helpful.

Clinician assessments
Clinicians will be asked to complete the intolerance of uncertainty scale. This will be done at the time of site set-up.
Following each patient consultation, clinicians will also complete a 6 item confidence/satisfaction scale.
Intervention typeBehavioural
Primary outcome measurePatients’ knowledge and understanding about GEP tests and risk of recurrence results measured by a knowledge interview prior to a patient receiving their GEP test results
Secondary outcome measures1. The impact of anxiety, intolerance of uncertainty and decisional conflict on decision-making (patient) assessed by the state (baseline and T2) and trait STAI measures (baseline), intolerance of uncertainty (T1) and decisional conflict measure (T2)
2. The confidence/satisfaction with GEP test result consultations (clinician) completed following the test result consultation
3. The agreement between clinician and patient on their treatment decision and whether this is influenced by the clinician’s satisfaction with interview about recurrence risk and IoU scores (clinician completes once per study prior to seeing patients), the patient’s recurrence risk, or pre-existing characteristics (trait anxiety, uncertainty) and whether GEP knowledge/understanding mitigate these
