Trial summary

RATIONALE: Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict whether cancer will come back after treatment. Read more about this study

About this study

Official title: Identifying Genomic Predictors of Recurrence After Adjuvant Chemotherapy

RATIONALE: Studying samples of tumor tissue from patients with cancer in the laboratory may help doctors learn more about changes that occur in DNA and identify biomarkers related to cancer. It may also help doctors predict whether cancer will come back after treatment.

PURPOSE: This laboratory study is identifying genes that may help predict recurrence in women with breast cancer treated with chemotherapy.

Read the detailed description

OBJECTIVES:

  • Assess the prognostic utility of the Oncotype DX™ 21 gene profile for risk of relapse in women with node positive or high-risk node negative breast cancer.
  • Identify individual genes whose RNA expression is associated with an increased risk of relapse in these patients.
  • Perform an exploratory analysis of individual genes whose RNA expression is associated with an increased risk of relapse differentially in patients previously treated with docetaxel.

OUTLINE: This is a multicenter study.

Tissue samples are examined for association of RNA expression and clinical factors (e.g., tumor size, nodal status, hormone receptor status, age, menopause status), as well as estrogen receptor, progesterone receptor, and HER-2/neu expression by immunohistochemistry and other studies.

PROJECTED ACCRUAL: A total of 900 patients will be accrued for this study.

Being tested
microarray analysis, protein expression analysis, immunohistochemistry staining method, laboratory biomarker analysis
Keywords
estrogen receptor, HER-2, PgR, stage II breast cancer, stage IIIA breast cancer, stage IIIB breast cancer
Medical subject headings

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

What is being measured

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

  1. Distant, local/regional, and ipsilateral breast relapse

  2. First breast cancer recurrence

  3. Relapse-free interval

Secondary outcomes (3)
  1. Distant involvement at time of first recurrence

  2. Disease-free survival

  3. Overall survival

Questions about this trial

What is this clinical trial studying?

An observational study of Breast Cancer and Estrogen Receptor, run by Eastern Cooperative Oncology Group.

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

Who may be eligible to take part?

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 17 May 2017. Status can change between updates, so confirm with the study contact before making plans.

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?

Distant, local/regional, and ipsilateral breast relapse. The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00897299, which also lists 2 linked publications.

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 17 May 2017.
