S8814A Biomarkers in Predicting Outcome in Postmenopausal Women With Hormone Receptor-Positive, Node-Positive Breast Cancer Treated With Tamoxifen With or Without Cyclophosphamide, Doxorubicin, and Fluorouracil

Completed

Conditions studied: Breast Cancer

In brief

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 how patients will respond to treatment. PURPOSE: This laboratory study is looking at biomarkers in predicting outcome in postmenopausal women with hormone receptor-positive, node-positive breast cancer treated with tamoxifen with or without cyclophosphamide, doxorubicin, and fluorouracil.
