Trial Information

A Pilot Trial of Tamoxifen and 4-HPR (4-N-Hydroxyphenyl Retinamide) in Persons at High Risk for Developing Breast Cancer


This is a pilot chemo-prevention study of the combination tamoxifen and 4-HPR in persons at
increased risk of developing invasive breast cancer. The objectives of the study are to
determine the acute and cumulative toxicity of tamoxifen and 4-HPR in high risk persons; to
assess the feasibility of obtaining adequate tissue to study potential intermediate
biomarkers of proliferative disease and malignancy using nipple aspiration, four quadrant
fine needle aspirates, and breast core needle biopsies; and to study the effects of
tamoxifen and 4-HPR on TGF-beta isoforms and the proliferative markers ki67 and PCNA pre-
and post-therapy.

Inclusion Criteria


POPULATION CHARACTERISTICS:

Women and men at increased risk for the development of breast cancer by at least one of
the following criteria:

Histologically documented ductal carcinoma in situ (DCIS), including DCIS with minimal
invasion or microinvasion.

Histologically documented lobular neoplasia, including lobular hyperplasia and lobular
carcinoma in situ (LCIS).

Histologically documented atypical ductal hyperplasia in postmenopausal women.

Histologically documented atypical ductal hyperplasia in premenopausal women with 1
first-degree relative (mother or sister) diagnosed with breast cancer.

Histologically documented atypical ductal hyperplasia in premenopausal women with 3 or
more relatives diagnosed with breast cancer provided at least 1 is a second-degree
relative.

3 or more first- or second-degree relatives diagnosed with breast or ovarian cancer with
at least 1 diagnosed with breast cancer.

2 or more premenopausal (under age 50) first-degree relatives diagnosed with breast
cancer.

1 or more first-degree relatives diagnosed with breast cancer if at least 1 relative in
the extended pedigree had ovarian cancer.

3 or more relatives with breast cancer with at least 1 first-degree relative diagnosed
with premenopausal breast cancer.

Previously diagnosed Stage I breast cancer with surgery and/or radiotherapy only (without
prior adjuvant chemo- or hormonal therapy).

Positive for the BRCA1/BRCA2 gene.

No evidence of malignancy on breast and gynecologic exams.

Participants with a family history of breast cancer will be seen in consultation by the
Family Studies Branch, NCI.

PRIOR/CONCURRENT THERAPY:

Mastectomy or lumpectomy plus radiotherapy required prior to entry for patients with DCIS.
Patients with DCIS who have participated in protocol NCI-MB-348 eligible.

No participation in any other breast cancer prevention study involving pharmacologic
intervention.
