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.

Condition Intervention
Breast Cancer
Estrogen Receptor
Genetic: microarray analysis
Genetic: protein expression analysis
Other: immunohistochemistry staining method
Other: laboratory biomarker analysis

Study Type: Observational
Official Title: Identifying Genomic Predictors of Recurrence After Adjuvant Chemotherapy

Further study details as provided by Eastern Cooperative Oncology Group:

Primary Outcome Measures:
  • Distant, local/regional, and ipsilateral breast relapse
  • First breast cancer recurrence
  • Relapse-free interval

Secondary Outcome Measures:
  • Distant involvement at time of first recurrence
  • Disease-free survival
  • Overall survival

Estimated Enrollment: 900
Actual Study Start Date: October 7, 2005
Study Completion Date: October 8, 2005
Primary Completion Date: October 8, 2005 (Final data collection date for primary outcome measure)
Detailed Description:


  • 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.
