About this study

Official title: A Study Assessing the Impact of the Oncotype DX DCIS Score on Radiotherapy Decision Making in the United Kingdom

Prospective single centre study of patients with DCIS that have undergone breast conservation surgery.

Read the detailed description

This is a single centre (Royal Marsden Hospital - Chelsea and Sutton) non-randomised trial investigating whether the Oncotype DX DCIS score changes the radiotherapy recommendation made by clinical oncologists in patients with low to moderate risk DCIS following breast conserving surgery.

  • ONCOTYPE DX DCIS testDiagnostic test

    The Oncotype DX DCIS score, comprised of 12 of the 21 genes of the Oncotype DX Recurrence score, has been developed by Genomic Health Inc.

    Two clinical utility studies have now been performed in USA, assessing the value of the Oncotype DX DCIS to clinical decision making (18,19) The first study by Alvarado et al. evaluated the influence of the test in 10 centres and in 115 patients (18). The DCIS score led to a change in the treatment recommendation in 36 patients (31.3%; 26 patients had a change to no radiation and 10 patients had a change to recommend radiation). The second study similarly showed change in recommendations following the Oncotype DX DCIS test in 26.4% of cases. It is unclear what the impact of the DCIS score test would be in the UK.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Change in radiotherapy recommendation by clinician

    Percentage of clinical oncology recommendations regarding radiotherapy that change pre- and post- Oncotype DX DCIS.

    Measured: end of trial (2 years)

Secondary outcomes (7)
  1. Determine whether the Oncotype DX DCIS score results in a change in patient decision for adjuvant radiotherapy.

    Percentage of patients who change their decision regarding radiotherapy pre- and post- Oncotype DX DCIS.

    Measured: end of trial (2 years)

  2. Determine whether the local recurrence risk estimated by clinical oncologists agrees with the local recurrence risk calculated by the Oncotype DX DCIS score (for all recurrences and for invasive recurrences only).

    Agreement between the local recurrence risk estimated by clinical oncologists and the local recurrence risk calculated by the Oncotype DX DCIS score (for all recurrences and for invasive recurrences only).

    Measured: end of trial (2 years)

  3. Determine change in patient decisional conflict pre and post Oncotype DX DCIS.

    Change in patient decisional conflict scale (DCS) scores pre and post Oncotype DX DCIS

    Measured: end of trial (2 years)

  4. Determine change in patient anxiety pre and post Oncotype DX DCIS.

    Change in state anxiety and trait anxiety scores using the State Trait Anxiety Inventory (STAI) pre and post ONCOTYPE DX DCIS test

    Measured: end of trial (2 years)

  5. Determine patient, tumour and clinician factors that are associated with clinicians changing their decision regarding radiotherapy.

    Patient, tumour and clinician factors (data collected during Visit 1) that are associated with clinicians changing their decision regarding radiotherapy.

    Measured: end of trial (2 years)

  6. Determine patient, tumour and clinician related factors that are associated with patients changing their decision regarding radiotherapy.

    Patient, tumour and clinician related factors (data collected during Visit 1) that are associated with patients changing their decision regarding radiotherapy.

    Measured: end of trial (2 years)

  7. Determine patient, tumour and clinician related factors that are associated with patients' final decision to have radiotherapy.

    Patient, tumour and clinician factors that are associated with patients' final decision to have radiotherapy.

    Measured: end of trial (2 years)

Questions about this trial

What is this clinical trial studying?

A study testing ONCOTYPE DX DCIS test in people with Breast Cancer, run by Royal Marsden NHS Foundation Trust at 1 site in United Kingdom.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 21 Sep 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United Kingdom. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Change in radiotherapy recommendation by clinician (time frame: end of trial (2 years)). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Sep 2023.
