Broccoli Sprout Extract in Treating Patients With Estrogen Receptor-Positive Breast Cancer - Full Text View

Purpose

This randomized pilot trial studies broccoli sprout extract in treating patients with estrogen receptor-positive breast cancer. Broccoli sprout extract contains ingredients that may prevent or slow the growth of certain cancers

Primary Outcome Measures:

Changes in cell proliferation (Ki-67) [ Time Frame: Baseline to 14 days ] [ Designated as safety issue: No ]
Appropriate transformation (such log transformation) will be used to achieve normality of the data. Results will be given as the back-transformed geometric means and 95% confidence intervals in order to preserve the units of measurement. Change in immunohistochemistry measures will be calculated for each individual and compared between treatment and placebo groups by use of independent samples t-test. If the normality could not be reached by transformation, Wilcoxon rank-sum test will be used, which considers both the direction and the magnitude of changes.
Changes in apoptosis (cleaved caspase 3) [ Time Frame: Baseline to 14 days ] [ Designated as safety issue: No ]
Appropriate transformation (such log transformation) will be used to achieve normality of the data. Results will be given as the back-transformed geometric means and 95% confidence intervals in order to preserve the units of measurement. Change in immunohistochemistry measures will be calculated for each individual and compared between treatment and placebo groups by use of independent samples t-test. If the normality could not be reached by transformation, Wilcoxon rank-sum test will be used, which considers both the direction and the magnitude of changes.
Changes in estrogen receptor expression (ER alpha and ER beta) [ Time Frame: Baseline to 14 days ] [ Designated as safety issue: No ]
Appropriate transformation (such log transformation) will be used to achieve normality of the data. Results will be given as the back-transformed geometric means and 95% confidence intervals in order to preserve the units of measurement. Change in immunohistochemistry measures will be calculated for each individual and compared between treatment and placebo groups by use of independent samples t-test. If the normality could not be reached by transformation, Wilcoxon rank-sum test will be used, which considers both the direction and the magnitude of changes.
Changes in NQO1 expression [ Time Frame: Baseline to 14 days ] [ Designated as safety issue: No ]
Appropriate transformation (such log transformation) will be used to achieve normality of the data. Results will be given as the back-transformed geometric means and 95% confidence intervals in order to preserve the units of measurement. Change in immunohistochemistry measures will be calculated for each individual and compared between treatment and placebo groups by use of independent samples t-test. If the normality could not be reached by transformation, Wilcoxon rank-sum test will be used, which considers both the direction and the magnitude of changes.

Arms	Assigned Interventions
Experimental: Arm I (broccoli sprout extract) Patients receive broccoli sprout extract PO QD on days 1-14.	Drug: broccoli sprout extract Given PO Other: laboratory biomarker analysis Correlative studies
Placebo Comparator: Arm II (placebo) Patients receive placebo PO QD on days 1-14.	Other: placebo Given PO Other Name: PLCB Other: laboratory biomarker analysis Correlative studies

Detailed Description:

PRIMARY OBJECTIVES:

I. To determine whether isothiocyanate-rich broccoli sprout extract (ITC-BSE) modifies biomarkers in breast tumor cells.

II. To determine whether the intervention alters proliferative and apoptotic markers (Ki-67 and cleaved caspase-3).

III. To determine whether the intervention down-regulates the expression of estrogen receptor (ER).

IV. To determine whether the intervention induces NAD(P)H dehydrogenase (quinone) 1 (NQO1) expression.

SECONDARY OBJECTIVES:

I. To determine tolerability of ITC-BSE and compliance in breast cancer patients.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM I: Patients receive broccoli sprout extract orally (PO) once daily (QD) on days 1-14.

ARM II: Patients receive placebo PO QD on days 1-14.

After completion of study treatment, patients are followed up at 30 days.

Eligibility

Ages Eligible for Study:	21 Years and older
Genders Eligible for Study:	Female
Accepts Healthy Volunteers:	No

Criteria

Inclusion Criteria:

Postmenopausal (no menstrual cycle in the past 12 months), because menstrual cycle affects baseline expression of biomarkers such as Ki-67
Diagnosed with incident, primary, invasive, ductal or lobular, or other epithelial malignancy, clinical stage I or II, ER positive breast cancer
No neoadjuvant endocrine therapy or chemotherapy
No prior chemotherapy
Have an Eastern Cooperative Oncology Group (ECOG) performance status of =< 2
Willing to avoid cruciferous vegetable intake during the study period (2 weeks)
Demonstrate the ability to swallow and retain oral medication
Subject or legal representative must understand the investigational nature of this study and sign an Independent Ethics Committee/Institutional Review Board approved written informed consent form prior to receiving any study related procedure

Exclusion Criteria:

Prior invasive breast cancer, prior mastectomy or breast radiation
Current or recent use of reproductive hormone therapy, tamoxifen, aromatase inhibitor or other estrogen inhibitors within the last 90 days, which may affect biomarkers
Intolerance to broccoli/ITC-BSE taste
Current ingestion of broccoli sprout extract, which may confound study results
Current or recent treatment for any malignancy within the last one year, which may affect biomarkers
History of Crohns' disease, celiac sprue or other malabsorption syndrome which may interfere with digestion and absorption of broccoli sprout extract
