  Purpose

RATIONALE: Studying samples of tumor tissue in the laboratory from Native American women with breast cancer may help doctors identify and learn more about biomarkers related to breast cancer in these patients. It may also help doctors learn more about the prognosis of these patients.

PURPOSE: This laboratory study is looking at biomarkers in Native American women with breast cancer.

Primary Outcome Measures:
  • Evaluation of a selected panel of molecular markers in tissue specimens from Native American women with breast cancer [ Time Frame: Up to 5 years ] [ Designated as safety issue: No ]
  • Determination of which molecular markers provide independent prognostic information with respect to traditional prognostic factors [ Time Frame: Up to 5 years ] [ Designated as safety issue: No ]
  • Comparison of the prevalence of positivity in Native American women with breast cancer with an age- and stage-matched cohort of Caucasian women with breast cancer enrolled on clinical trial NCCTG-77-30-51 or the Mayo Breast Cancer Registry [ Time Frame: Up to 5 years ] [ Designated as safety issue: No ]

Groups/Cohorts Assigned Interventions
Group I
Immunohistochemistry is performed on tumor samples to analyze the following molecular markers: estrogen receptor, progesterone receptor, c-erbB2, p53, Ki-67, Bcl-2, Bax, cyclin D-1, and insulin-like growth factor-1R. PROJECTED ACCRUAL: A total of 300 tissue samples (150 from Native American women and 150 from Caucasian women) will be accrued for this study.
Other: immunohistochemistry staining method Other: laboratory biomarker analysis

Detailed Description:

OBJECTIVES:

  • Evaluate a selected panel of molecular markers in tissue specimens from Native American women with breast cancer.
  • Determine which molecular markers provide independent prognostic information with respect to traditional prognostic factors in these patients.
  • Compare and contrast the prevalence of positivity in Native American women with breast cancer with an age- and stage-matched cohort of Caucasian women with breast cancer enrolled on clinical trial NCCTG-77-30-51 or the Mayo Breast Cancer Registry.

OUTLINE: Immunohistochemistry is performed on tumor samples to analyze the following molecular markers: estrogen receptor, progesterone receptor, c-erbB2, p53, Ki-67, Bcl-2, Bax, cyclin D-1, and insulin-like growth factor-1R.
