  Purpose

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 plan the best treatment.

PURPOSE: This research study is looking at tissue samples from women who underwent chemotherapy for lymph node-positive stage II or stage IIIA breast cancer.

Primary Outcome Measures:
  • Disease-free survival [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Overall survival [ Designated as safety issue: No ]

Estimated Enrollment: 1195
Study Start Date: July 2008
Estimated Primary Completion Date: February 2009 (Final data collection date for primary outcome measure)
Detailed Description:

OBJECTIVES:

Primary

  • To identify biomarkers that can be used to individually tailor the use of adjuvant dose-dense therapy in women with stage II or IIIA breast cancer.

Secondary

  • To identify groups of patients who have a poor prognosis despite adjuvant chemotherapy and who should be prospectively targeted for new approaches to adjuvant treatment.

OUTLINE: This is a multicenter study.

Tissue samples are collected from patients. Tissue samples are analyzed by immunohistochemistry (Ki67, CK5/6, EGFR, ER) and fluorescence in situ hybridization (FISH).
