Study Arms:
- Arm I: Exemestane 25 mg QD (Type: EXPERIMENTAL): Patients receive exemestane PO QD on days 1-7. Cycles repeat every 7 days for 4-6 weeks in the absence of disease progression or unacceptable toxicity. Patients then undergo surgery on days 29, 36, or 43.
- Arm II: Exemestane 25 TIW (exemestane, placebo) (Type: EXPERIMENTAL): Patients receive exemestane PO QD on days 1, 3, and 5. Patients also receive placebo PO QD on days 2, 4, 6, and 7. Cycles repeat every 7 days for 4-6 weeks in the absence of disease progression or unacceptable toxicity. Patients then undergo surgery on days 29, 36, or 43.
- Arm III: Exemestane 25 mg QW (exemestane, placebo) (Type: EXPERIMENTAL): Patients receive exemestane PO QD on day 1 and placebo PO QD on days 2-7. Cycles repeat every 7 days for 4-6 weeks in the absence of disease progression or unacceptable toxicity. Patients then undergo surgery on days 29, 36, or 43.

Based on this trial design, predict the completion outcome and termination type (if applicable).
