About
RATIONALE: Diagnostic procedures, such as breast duct endoscopy, may improve the ability to detect breast cancer earlier and plan more effective treatment.
PURPOSE: This phase II trial is studying how well breast duct endoscopy works in assessing cellular atypia (abnormal cells) in the breast ducts of women with a genetic risk for breast cancer.
Full description
OBJECTIVES:
Primary
Secondary
OUTLINE: Patients undergo nipple aspiration to identify productive ducts and collect fluid for tumor marker assessment followed by ductal lavage over 15 minutes. Patients undergo duct endoscopy over approximately 30 minutes under local anesthesia. If no abnormality is found, duct endoscopy is repeated in 6 months. If the repeat duct endoscopy is normal, patients continue to undergo nipple aspiration or ductal lavage as specified in protocols RMNHS-2242 and RMNHS-2269. If an abnormality is found during either the initial or repeat duct endoscopy, patients may undergo further assessment comprising imaging or biopsy and/or appropriate surgical intervention.
Fluid is analyzed for tumor markers by immunohistochemistry. Candidate genes are analyzed by gene methylation studies, gene expression arrays, and proteomic analysis.
Patients are followed for at least 5 years.
PROJECTED ACCRUAL: A total of 45-60 patients will be accrued for this study within 2 years.
