Phase III Comparison of Adjuvant Chemoendocrine Therapy With CAF and Concurrent or Delayed Tamoxifen to Tamoxifen Alone in Postmenopausal Patients With Involved Axillary Lymph Nodes and Positive Receptors
In Brief
A Phase 3 clinical trial evaluating cyclophosphamide, doxorubicin hydrochloride, and 8 other interventions for Breast Cancer. Completed, enrolled 1,558 participants.
Detailed Summary
RATIONALE: Estrogen can cause the growth of breast cancer cells. Hormone therapy using tamoxifen may fight breast cancer by blocking the use of estrogen by the tumor cells. Drugs used in chemotherapy, such as doxorubicin, cyclophosphamide, and fluorouracil, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. It is not yet known whether giving tamoxifen alone is more effective in treating breast cancer than giving tamoxifen together with chemotherapy or after chemotherapy. PURPOSE: This randomized phase III trial is studying giving tamoxifen with or without combination chemotherapy to compare how well they work in treating postmenopausal women who have undergone surgery for breast cancer.
