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 Intervention Phase
Operable Breast Neoplasms Drug: letrozole (Femara) Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Randomized Trial of Endocrine Therapy Against Locoregional Therapy First. A DBCG Trial in Postmenopausal Patients With Operable Hormone Receptor Positive Tumors Larger Than 2 cm.
