A randomised, phase III, bifactorial clinical trial for ER positive postmenopausal early breast cancer to determine whether the addition of a COX 2 inhibitor to a 16 week treatment regimen of pre-operative exemestane or letrozole results in greater clinical response, with acceptable toxicity, than an aromatase inhibitor alone; and to determine whether exemestane provides greater objective clinical response than letrozole in the neoadjuvant setting
