PURPOSE: Screening trial to compare specific biomarkers based on fine-needle aspiration specimens from women at increased or normal risk of breast cancer.
- Compare specific biomarkers, including cellular morphology (cytology), proliferation index (Ki-67), p53 expression, and LOH in chromosome 9p at locus DS9157, in fine needle aspirate specimens from women at increased vs normal risk of breast cancer.
- Determine whether these specimens are adequate to perform the biomarker assays and whether this technique could be used in the general outpatient setting.
- Determine whether biomarker levels in these patients are concordant or discordant with individual clinical risk of breast cancer.
- Determine whether 1 or more biomarkers can distinguish high-risk from control patients.
- Correlate specific biomarkers and changes in biomarker levels with pathologic diagnosis from the breast biopsy.
OUTLINE: Patients undergo fine needle aspiration of normal appearing breast tissue prior to the beginning of elective surgery. Specimens are analyzed for the presence of specific biomarkers.
PROJECTED ACCRUAL: Approximately 156 patients will be accrued for this study within 3 years.
Primary Purpose: Screening
cytology specimen collection procedure, comparison of screening methods, study of high risk factors

Methods or procedures used to obtain samples of URINE.
Laboratory processes prior to specimen analysis. These processes include study design, compliance of the subjects investigated, compliance in adherence to protocols, choice of specimens utilized and sample collection.
Comparison of various psychological, sociological, or cultural factors in order to assess the similarities or diversities occurring in two or more different cultures or societies.
Comparison of outcomes, results, responses, etc for different techniques, therapeutic approaches or other inputs.
The identification of selected parameters in newborn infants by various tests, examinations, or other procedures. Screening may be performed by clinical or laboratory measures. A screening test is designed to sort out healthy neonates (INFANT, NEWBORN) from those not well, but the screening test is not intended as a diagnostic device, rather instead as epidemiologic.
