About this study

A prospective population-based cohort study is being conducted in Ontario to evaluate whether the performance of Oncotype DX® changes the treatment recommended and the treatment received in women or men with node negative, ER positive breast cancer who are receiving (or will receive) endocrine therapy and who are candidates for chemotherapy. One thousand eligible consenting women and men will have their tumor tissue specimen sent to Genomic Health where the Oncotype DX® assay will be performed.

Read the detailed description

The evidence supporting the adoption of Oncotype DX® is relatively weak by the criteria used by the Ontario Health Technology Advisory Committee (OHTAC). There is only one small published prospective study that reports on Oncotype DX® changing clinical management. The economic models that estimated the potential advantages of using an Oncotype DX® guided treatment strategy may have overestimated the benefits because they assumed that all patients with tumors >1cm in the absence of Oncotype DX® testing would receive chemotherapy in addition to tamoxifen, and that the magnitude of benefit with chemotherapy over tamoxifen is relatively large, i.e. reduces recurrence risk by 74% and associated with an absolute benefit of 28%. (The benefit comes from one trial and is applied to all patients). It is estimated that there are about 3,300 incident cases with node negative, ER positive, HER2 neu negative tumors annually in Ontario, it is important to evaluate the adoption of this test for decision making in Ontario.

What is being measured

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

  1. Change in treatment recommendation

    The primary outcome is the change in treatment recommendation by the oncologist and the change in treatment preference of the patient.

    Measured: One month

Secondary outcomes (3)
  1. Association between Oncotype DX® RS with other estimated risk calculations

    The level of association between the Oncotype DX® RS with estimated recurrence risk calculated by Adjuvant! Online, as well as with traditional factors including tumor size, grade, and HER2 neu.

    Measured: One month

  2. Change in patient decisional conflict

    The change in the level of patient decisional conflict measured by the Decisional Conflict Scale (DCS). Additionally, the DCS has three subscales: uncertainty, effective decision making, and factors contributing to uncertainty. The change in each of these subscales will also be measured.

    Measured: One month

  3. Robustness of economic model of sequential Adjuvant! Online followed by Oncotype DX®.

    To determine the robustness of the economic model of sequential Adjuvant! Online followed by Oncotype DX®.

    Measured: 6 months

Questions about this trial

What is this clinical trial studying?

A study testing ONCOTYPEDX Test in people with Breast Cancer, run by Ontario Clinical Oncology Group (OCOG) at 35 sites in Canada.

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 8 inclusion and 6 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: finished, as of the sponsor's last update on 27 Mar 2014. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 35 sites in Canada. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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 treatment recommendation (time frame: One month). 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 27 Mar 2014.
