Brief Summary:

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 tissue samples from women treated with paclitaxel for breast cancer on clinical trial CALGB 9344 or CALGB 9741.

Group/Cohort Intervention/treatment
Group 1
Tissue blocks from CALGB-9344 and CALGB-9741 are utilized to purify RNA to be tested in the PAM50 assay (a 50-gene quantitative PCR assay, that provides an intrinsic breast cancer subtype diagnosis) and generate risk of relapse (ROR) scores. For more information, see Details section.
