简要总结
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.
详细描述
OBJECTIVES:
Primary
- Correlate cell yield and morphology findings from ductal lavage with duct endoscopy findings and any subsequent surgical pathology findings in high-risk women with BRCA1, BRCA2, or p53 gene mutations who have cellular atypia.
- Determine the prevalence of occult breast cancer in patients with cellular atypia undergoing duct endoscopy.
Secondary
- Determine patient acceptance of duct endoscopy.
- Perform immunohistochemical analysis (including estrogen receptor, progesterone receptor, HER2-neu receptor, epidermal growth factor receptor, p53, and proliferation marker expression) for markers potentially associated with breast cancer in these patients.
- Determine potential molecular markers of malignancy by gene methylation, gene expression, and proteomics in these patients.
