  Purpose
This is a Phase II non-randomized, open, uncontrolled and bi-centric study of hormonal induction by exemestane (Aromasin) + tamoxifen to evaluate the effectiveness of exemestane (Aromasin) with tamoxifen on the rate of clinical response menopausal in patients with tumors of locally advanced breast. Hormone therapy will be administered at a dose of 25mg/day for exemestane and 20 mg / day for 4 months for tamoxifen.

Condition Intervention Phase
Breast Neoplasms Drug: Exemestane Drug: tamoxifen Phase 2

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Phase II Study Evaluating the Effectiveness of the Exemestane (Aromasin) With Tamoxifen on the Rate of Clinical Response Menopausal in Patients With Locally Advanced Breast Tumors
