  Purpose

RATIONALE: Broccoli sprout extract supplements may slow the growth of tumor cells or abnormal cells and may be an effective treatment for ductal carcinoma in situ and/or atypical ductal hyperplasia.

PURPOSE: This randomized phase II trial is studying how well broccoli sprout extract works in treating women with a diagnosis of breast cancer, ductal carcinoma in situ and/or atypical ductal hyperplasia.

Enrollment: 66
Study Start Date: August 2009
Estimated Primary Completion Date: May 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Arm I
Patients receive oral broccoli sprout extract supplementation three times daily for 2-8 weeks in the absence of unacceptable toxicity.
Dietary Supplement: broccoli sprout extract
Given orally
Placebo Comparator: Arm II
Patients receive oral placebo supplementation three times daily for 2-8 weeks in the absence of unacceptable toxicity.
Other: placebo
Given orally

Detailed Description:

OBJECTIVES:

  • To determine the correlation between supplemental sulforaphane (broccoli sprout extract) dose and concentrations of sulforaphane and its metabolites in blood and urine samples from women positive for cancer, ductal carcinoma in situ and/or atypical ductal hyperplasia.
  • To determine the effect of this supplement on biomarkers of prognosis in these patients.
  • To determine the effect of this supplement on HDAC inhibition in peripheral blood cell and normal and cancerous breast tissue samples from these patients.

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

  • Arm I: Patients receive oral broccoli sprout extract supplementation three times daily for 2-8 weeks in the absence of unacceptable toxicity.
  • Arm II: Patients receive oral placebo supplementation three times daily for 2-8 weeks in the absence of unacceptable toxicity.

Blood and urine samples are collected at baseline and after completion of study treatment for laboratory biomarker studies. Patients scheduled to undergo surgery (mastectomy or lumpectomy) also undergo breast tissue sample collection at baseline and at the time of surgery. Samples are analyzed for sulforaphane metabolism (isothiocyanate levels), HDAC activity (acetylated histone expression), cell proliferation (Ki-67 index by IHC), and apoptosis (TUNEL assay).

Patients complete questionnaires at baseline and periodically during study about their dietary history, family history, cruciferous vegetable intake, adverse events, and dietary and medication changes.

After completion of study therapy, patients are followed at/around 30 days.
