简要总结
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.
详细描述
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.
