Blood Tumor Markers for Molecular Diagnosis of Breast Diseases and Monitoring of Breast Cancer Treatment and Follow-up
Blood Tumor Markers for Molecular Diagnosis of Breast Diseases and Monitoring of Breast Cancer Treatment and Follow-up
RATIONALE: Collecting and storing samples of blood and tumor tissue from patients with cancer to test in the laboratory may help the study of cancer in the future.
PURPOSE: This clinical trial is studying blood and tumor tissue samples in women with invasive breast cancer, ductal carcinoma in situ, lobular carcinoma in situ, or benign breast disease.
OBJECTIVES:
Primary
Secondary
OUTLINE: Patients undergo baseline peripheral blood specimen collection pre-biopsy and then periodically for up to 10 years. Specimens are analyzed for circulating tumor cells via quantitative real-time reverse-transcriptase PCR, immunofluorescence, and bidirectional pyrophosphorolysis-activated polymerization allele-specific amplification; and for protein profiles via mass spectometry, liquid chromatography, enzyme digestion, and tandem mass spectometry. Patients' tumor tissue (invasive breast cancer [IBC] only) is analyzed for p53 via IHC. Medical records are reviewed periodically.
Patients with IBC complete a quality of life assessment at baseline and every 6 months for up to 10 years.
DISEASE CHARACTERISTICS:
Biopsy-confirmed diagnosis of one of the following:
Stage I-IV infiltrating ductal or infiltrating lobular carcinoma
Ductal carcinoma in situ
Lobular carcinoma in situ
Benign breast disease
