Hormone Therapy and Chemotherapy in Treating Perimenopausal or Postmenopausal Women With Node-Positive Breast Cancer
Completed
International Breast Cancer Study Group
Phase 3
1993-05-01
RATIONALE: Estrogen can stimulate the growth of breast cancer cells. Hormone therapy may
fight breast cancer by blocking the uptake of estrogen. Drugs used in chemotherapy use
different ways to stop tumor cells from dividing so they stop growing or die. Combining
chemotherapy with hormone therapy may kill more tumor cells. It is not yet known which
treatment regimen is more effective for breast cancer.
PURPOSE: Randomized phase III trial to compare the effectiveness of hormone therapy during or
after combination chemotherapy or hormone therapy alone in treating perimenopausal or
postmenopausal women who have stage II or stage IIIA breast cancer.
