Brief Summary:
The hypothesis to be addressed in this randomized phase III trial is that 4 months of letrozole may be superior to surgery as primary therapy for early stage hormone receptor positive breast cancer in postmenopausal women, provided that these patients will receive definitive and radical surgery and adjuvant therapies as otherwise indicated at the completion of preoperative letrozole.

Condition or disease Intervention/treatment Phase
Operable Breast Neoplasms Drug: letrozole (Femara) Phase 3
