Assessment
Primary outcomes Determine the clinical response rate.
Determine the incidence of adverse events.
Key secondary outcomes Determine the long-term outcomes (overall survival, relapse free survival).
Determine the rate of improvement in surgical outcomes (breast conserving rate, local recurrence rate).
Determine the rate of axillary lymph node involvement and pathologic response. Examine the change of biomarker (e.g., Ki-67, TUNEL, bcl-2, M-30) with this treatment.

Number of participants that the trial has enrolled 116
Results 
Between March 2006 and December 2007, 116 patients were enrolled. Among those, 102 patients completed 24 weeks administration. The ORR was 47% (55/116) at week 16 and 51% (59/116) at week 24, respectively. No serious toxicity was seen. At diagnosis, 59 patients (51%) would have required mastectomy but 40 patients were converted to BCS, showing an increase in the rate of BCS (77%). The 24-week aromatase inhibition provided preferable clinical benefits with significant reduction in Ki67 index.

Baseline Characteristics 
Between March 2006 and December 2007 a total of 116 patients were enrolled. T2 stage were 110 cases and N0 were 91 cases. All patients were defined as ER-positive, 80 (68.9%) were PgR-positive and 3(2.5%) were HER2-positive by investigator evaluation.
Participant flow 
During the first 16 weeks, 10 patients discontinued neoadjuvant exemestane treatment because of PD (4 patients), investigator decision (1 patient), adverse events (2 patients, 1 of whom was not evaluable at Week 16), or patients decision (3 patients, 2 of whom were not evaluable at Week 16).  102 patients completed 24 weeks of exemestane neoadjuvant treatment.
Adverse events 
The most frequently seen adverse events were an abnormal increase in liver enzyme levels (SGOT, SGPT and ALP), hot flush, joint pain, hypoalbuminuria and elevated creatinine and bilirubin levels. None of these adverse events were deemed to be severe in intensity. The only Grade 3 adverse events were elevated liver enzymes in four cases.
Outcome measures 
The primary end points were objective response rates (ORR) and safety after 16 and 24 weeks of treatment in intent to treatment analysis.
