Brief Summary:
Find a genetic signature of de novo resistance to letrozole in adjuvant breast cancer;
Detailed Description:
The aromatase inhibitors are drugs already approved for the treatment of breast cancer in the adjuvant and metastatic setting, and have demonstrated a superiority when compared to other hormone therapy agents as tamoxifen. FRAGRANCE is a trial of neoadjuvant hormone therapy activated in September 2004 at the Jules Bordet Institute. The main objective of this study is to find a genetic signature of de novo resistance to letrozole The standard dose of letrozol, 2,5 mg/day, is given orally during 4 months previous to the definitive breast surgery. The advantages of the neoadjuvant setting are a) the possibility to directly evaluate the response to therapy, which is of great value to decide adjuvant treatment; b) the increase chance of performing breast conserving surgery; c) and, because a tumor sample is obtained before and after treatment, the identification of predictive markers of response or resistance to treatment, including a genetic signature, obtained using the microarray technology. Eligible patients are women with early hormonal receptor positive breast cancer, with any contra-indication or refusal to the administration of chemotherapy The side effects of letrozole are already well known, and include more commonly hot flashes, nausea and vomiting, headache, arthralgia/myalgia, fatigue, and oedema. After surgery, adjuvant treatment will be done according to the standard practice of the Institute, considering the possibility of continuing letrozole for a total of at least 5 years, if a satisfactory response is achieved The first part of this trial will include 49 patients.
This trial will soon become a multicenter, multinational trial of 160 patients.
