Study Summary

This randomized phase III clinical trial studies how well tamoxifen citrate, anastrozole, letrozole, or exemestane with or without chemotherapy work in treating patients with breast cancer that has spread from where it began in the breast to surrounding normal tissue (invasive). Estrogen can cause the growth of breast cancer cells. Hormone therapy, using tamoxifen citrate, may fight breast cancer by blocking the use of estrogen by the tumor cells. Aromatase inhibitors, such as anastrozole, letrozole, and exemestane, may fight breast cancer by lowering the amount of estrogen the body makes. Drugs used in chemotherapy work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. It is not yet known whether giving tamoxifen citrate, anastrozole, letrozole, or exemestane is more effective with combination chemotherapy in treating patients with breast cancer.

Primary Outcome

From date of randomization (2nd Registration) to date of first invasive recurrence (local, regional or distant), second invasive primary cancer (breast or not), or death due to any cause. Patients last known to be alive who have not experienced recurrence or second primary cancer are censored at their last contact date. This is the STEEP definition of invasive disease-free survival. Kaplan-Meier estimates were calculated for the 5-year IDFS rate. Due to the results of the third prespecified int
