Description
Inclusion Criteria:
- Postmenopausal patients, defined as one or more of the following criteria:
Documented history of bilateral oophorectomy, Aged 60 years or more,
Aged 45-59 years and satisfying one or more of the following criteria:
Amenorrhea for at least 12 months and intact uterus Amenorrhea for less than 12 months and follicle stimulating hormone (FSH) concentrations within postmenopausal range including: patients who have had a hysterectomy and patients who have received hormone replacement therapy in the past.
- Clinically palpable or non-palpable T1c or greater, ER positive invasive breast cancer diagnosed by outside core biopsy.
- Outside diagnosis of invasive breast cancer confirmed at MSKCC
- Palpable or non-palpable breast mass > 1cm highly suspicious for invasive breast cancer based on mammographic, ultrasound and/or physical examination findings and amenable to diagnostic core biopsy.
- Core biopsy diagnosis of ER positive invasive breast cancer performed at MSKCC
- Breast conserving surgery or mastectomy scheduled at MSKCC.
- Informed consent obtained.
Exclusion Criteria:
- Co-morbid conditions which would preclude use of aromatase inhibitors such as: previous hypersensitivity, severe hepatic insufficiency (SGOT or SGPT three times the upper limit of normal), severe renal insufficiency (creatinine clearance <10ml/min).
Prior radiation therapy to chest wall / breast.
- Neoadjuvant chemotherapy
- Hormone replacement therapy, tamoxifen or raloxifene treatment within past 3 months
- ER negative breast cancer
- History of active malignancy within the previous 5 years (except for nonmelanoma skin cancer and breast cancer)

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: 1
This is an exploratory study utilizing micro-array technology and immunohistochemistry to test the hypothesis that changes in gene expression occur as an early event in response to endocrine therapy and that these changes can be correlated with changes in surrogate biological markers.

anastrozole 1mg/day 11 days before their surgery and to take the last dose of the oral endocrine agent (anastrozole) on the day before their surgery.
