Studying Blood and Tumor Tissue Samples in Women With Invasive Breast Cancer, Ductal or Lobular Carcinoma in Situ, or Benign Breast Disease

2014-08-27 03:22:16 | BioPortfolio


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.




- To establish a specimen bank from peripheral blood specimens collected from women with a full spectrum of breast disease (invasive breast cancer [IBC], ductal or lobular carcinoma in situ [CIS], or benign breast disease [BBD]) with standardized clinical follow up and serial specimen collection for those with IBC.

- To determine the ability of quantitative real-time reverse-transcriptase PCR (qRT-PCR) to discriminate between patients with IBC, CIS, and BBD by comparing baseline assay values from pre-biopsy specimens to the histologic diagnosis.

- To determine the ability of qRT-PCR to predict treatment response by comparing serial assay values from patients with evaluable IBC to their objective response.

- To determine the ability of qRT-PCR to predict relapse by comparing the serial assay values from all patients with IBC to their disease status.

- To determine the ability of qRT-PCR to perform as an independent prognostic factor by comparing baseline assay values from all patients with IBC to their disease status, stratified by known breast cancer prognostic factors.


- To perform exploratory studies identifying potential targets for novel nucleic acid and proteomic-based early detection assays.

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.

Medical and Biotech [MESH] Definitions

The use of techniques that produce a functional MUTATION or an effect on GENE EXPRESSION of a specific gene of interest in order to identify the role or activity of the gene product of that gene.

MOLECULAR BIOLOGY techniques used in the diagnosis of disease. Included are such techniques as IN SITU HYBRIDIZATION of chromosomes for CYTOGENETIC ANALYSIS; OLIGONUCLEOTIDE ARRAY SEQUENCE ANALYSIS of gene expression patterns in disease states; identification of pathogenic organisms by analysis of species specific DNA sequences; and detection of mutations with POLYMERASE CHAIN REACTION.

A method of chemical analysis based on the detection of characteristic radionuclides following a nuclear bombardment. It is also known as radioactivity analysis. (McGraw-Hill Dictionary of Scientific and Technical Terms, 4th ed)

A mutation that results in an increase in a gene's activity or in acquiring a new molecular function or a new pattern of gene expression.

Hybridization of a nucleic acid sample to a very large set of oligonucleotide probes, which are attached to a solid support, to determine sequence or to detect variations in a gene sequence or expression or for gene mapping.
