  Purpose

RATIONALE: Studying the genes expressed in samples of tumor tissue from patients with cancer may help doctors identify biomarkers related to cancer.

PURPOSE: This research study is looking at tumor tissue samples from patients who have undergone surgery for breast cancer.


Condition Intervention

Primary Outcome Measures:
  • Differential expression of candidate genes between normal and cancer breast tissues [ Time Frame: non-applicable ] [ Designated as safety issue: No ]
    Approximately 5 slides of each tumor will be collected to provide sufficient samples for replicate staining, if necessary, as well as a staining for a positive control


Biospecimen Retention:   Samples With DNA

Previously collected breast cancer tissue samples (paraffin embedded blocks) and normal adjacent tissue are used for immunohistochemistry studies of expression of candidate genes.


Estimated Enrollment: 80
Study Start Date: April 2008
Estimated Primary Completion Date: April 2014 (Final data collection date for primary outcome measure)

Criteria

DISEASE CHARACTERISTICS:

  • Diagnosis of breast cancer
  • Tissue samples available
  • Samples are selected based on presence or absence of tumor receptors, (i.e.; estrogen, progesterone, and HER2 receptors) and grouped into following 4 categories:

    • Estrogen receptor (ER)-positive/progesterone receptor (PR)-positive/HER2-negative
    • ER-positive/PR-positive/ HER2-positive by FISH
    • ER-negative/PR-negative/HER2-positive
    • ER-negative/PR-negative/HER2-negative(triple negative or basal-type cancers)

PATIENT CHARACTERISTICS:

  • Menopausal status not specified

PRIOR CONCURRENT THERAPY:

  • Not specified
