Establishment of Normal High Risk Breast Epithelial Cell Cultures, and A High Risk Cell Line and Tissue Repository From Breast Tissue From Women at High Risk of Breast Cancer

Background:

- Many risk factors for breast cancer have been identified, including family history,
endocrine background, changes in breast tissue, cancer in one breast, radiation
exposure, obesity and others. There is a spectrum of tissue changes seen in cancerous
and pre-cancerous breast tissue.

- A cell line is a collection of cells that are grown in the laboratory from an original
tissue specimen. Cell lines developed from high-risk breast tissue allow researchers to
perform metabolic and molecular studies of breast cells over time.

Objective: To establish a repository (facility in which tissue samples can be preserved and
stored for many years) of cell lines from high-risk breast tissue to allow researchers to
learn more about changes in breast cells that may cause them to develop into breast cancer.

Eligibility: Women between 20 and 80 years of age who:

- Have an increased risk of breast cancer because they are members of a high-risk breast
or ovarian cancer family.

- Have had breast cancer in one or both breasts.

- Have had radiation for lymphoma before the age of 30.

- Have a mutation in a breast cancer susceptibility gene, but whose family history is not
known.

- Are not at increased risk of breast cancer.

Design:

- A small piece of breast tissue will be obtained from about 10 women without an
identified risk of breast cancer and up to 100 women at high risk of developing breast
cancer.

- Cell lines will be developed from each high-risk category.

- The cell lines and tissues will be used to establish a repository of high-risk breast
cell lines and breast tissues that can be used to study how the cells develop into
breast cancer.

Background:

The NCI Surgery Branch

Multiple risk factors for breast cancer have been identified, including family history,
endocrine background, histologic changes in breast tissue, cancer in one breast, radiation
exposure, obesity, and others. The histologic phenotypes of breast carcinogenesis include a
spectrum of changes, beginning with normal appearing breast epithelium, progressing to
hyperplasia, atypical hyperplasia, in situ carcinoma, and finally invasive carcinoma.

Our present knowledge of high risk breast tissue is based on the study of a variety of
cellular sample types, which include fine needle aspirates, nipple aspirate fluid, core
needle biopsies, and breast tissue from mastectomy or segmentectomy specimens.

Valid preclinical models are needed which utilize homogenous human cellular material which
can be studied over time in large quantities.

A model which may be ideally suited to the metabolic and molecular studies of breast
epithelial cells is an in vitro cell line model developed from high risk breast tissue.

In this study normal breast tissue will be acquired from each of the high risk sites for
breast cancer in the breast. These tissues will be used to develop breast epithelial cell
lines for in vitro studies, and to establish a high risk cell line and tissue repository.

Objectives:

To acquire normal breast tissue from each of the high risk sites for breast cancer in the
breast.

To develop breast epithelial cell lines from the normal high risk breast tissue from each of
the major high risk sites.

To establish a repository of high risk breast epithelial cell lines and high risk normal
breast tissue which can be used as a resource for pilot studies at NIH and other
participating centers to characterize high risk breast epithelial cells

Eligibility:

Women age 20 - 80 years who have an increased risk of breast cancer because they are members
of a high risk breast or ovarian cancer family.

Women with a history of ipselateral breast cancer, either invasive or in situ, and a normal
contralateral breast by mammography (within the past 12 months) and a normal physical
examination of the contralateral breast and adjacent lymph node bearing areas, or be
undergoing prophylactic mastectomy.

Women without breast cancer but with a Gail model estimate of 5-year risk of breast cancer of
1.67 percent or higher.

Women with bilateral breast cancer (invasive or in situ) who have not received whole breast
irradiation to both breasts.

Women with a previous history of mediastinal irradiation for lymphoma before the age of 30
and who are now greater than 5 years since completing radiation therapy.

Normal women not at increased risk of breast cancer (Gail model Index of less than 1.50
percent) and without abnormal findings in the breast by physical examination and mammography
to serve as normal control tissue.

Women with a mutation in a breast cancer susceptibility gene, but whose family history is not
known.

Absence of significant cardiac, hepatic or renal disease, which, in the opinion of the PI, is
likely to cause metabolic changes in the breast tissue.

Design:

A tissue acquisition in which Normal breast tissue will be collected from women at high risk
of breast cancer at NIH and at other institutions as well. Centers collecting tissue for this
protocol must have IRB approval for this study and an IRB approved Informed Consent.

All breast tissue will be obtained from surgical specimens acquired as part of planned
surgical procedures. Short-term cell lines will be developed from this tissue and confirmed
cytologically and by expression of cytokeratins. Multiple cell lines from each of the high
risk categories will be developed.

These cell lines and the respective tissues will be used to establish a repository of high
risk breast epithelial cell lines and high risk breast tissues which can be used to further
define the carinogenic pathway for breast cancer. Early passages of these cell cultures and
the respective normal breast tissue will be stored for future studies.

100 patients will be enrolled over a period of 5 years.

- INCLUSION CRITERIA:

To be eligible, women must have one of the following:

Women 20-80 years of age who have an increased risk of breast cancer because they are
members of a high risk breast or ovarian cancer family. An Individual with a family history
of verified breast and/or ovarian cancer is defined as including one of the following: 1)
at least four cases of breast cancer. 2) Three cases of breast cancer and at least one case
of ovarian cancer (two cases of ovarian cancer of which have to be first degree relatives).
3) Two cases of ovarian cancer in first degree relatives. High risk families may also
include those with at least 4 cases of early onset (age less than 60) breast cancer or
ovarian cancer (diagnosis at any age), or any family known to segregate a mutation in BRCA1
or another predisposing gene (i.e. BRCA2).

Women with a history of ipsilateral breast cancer, either invasive or in situ, and a normal
contralateral breast by mammography (within the past 12 months) and a normal physical
examination of the contralateral breast and adjacent lymph node bearing areas, or be
undergoing prophylactic mastectomy.

Women without breast cancer but with a Gail model estimate of 5-year risk of breast cancer
of 1.67 percent or higher.

Women with bilateral breast cancer (invasive or in situ) who have not received whole breast
irradiation to both breasts.

Women with a previous history of mediastinal irradiation for lymphoma before the age of 30
and who are now greater than or equal to 5 years since completing radiation therapy.

Normal women not at increased risk of breast cancer (Gail model Index of less than 1.50%)
and without abnormal findings in the breast by physical examination and mammography to
serve as normal control tissue.

Women with a mutation in a breast cancer susceptibility gene, but whose family history is
not known.
