The purpose of this research is to examine the effect of a broccoli sprout preparation on specific factors in breast tissue that are related to breast cancer risk and to assess whether sulforaphane a key component of broccoli sprouts increases the levels of protective enzymes in breast tissue. In addition, the investigators will also examine how acceptable the broccoli sprouts preparation is to the study participants.

Condition Intervention Phase
Breast Cancer
Drug: Broccoli sprout extract (sulforaphane)
Dietary Supplement: Mango juice without extract
Phase 2

Further study details as provided by Sidney Kimmel Comprehensive Cancer Center:

Primary Outcome Measures:
  • A decrease in the mean proliferative rate measured by Ki67% [ Time Frame: 14 days ]

Secondary Outcome Measures:
  • An increase in mRNA transcript levels of specific cytoprotective enzymes known to be modulated by sulforaphane and related protein expression as well as qualitative assessment of morphological changes in DCIS specimens and adjacent normal tissue [ Time Frame: 14 days ]

Enrollment: 34
Study Start Date: April 2009
Study Completion Date: November 2013
Primary Completion Date: November 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Broccoli sprout extract and mango juice
Patients will be randomized to 14 day intervention of broccoli sprout extract consisting of a consistent dose of sulforaphane dissolved in mango juice compared to a placebo preparation of mango juice alone. All women will be on a cruciferous free diet for the duration of the study (14 days).
Drug: Broccoli sprout extract (sulforaphane)
Women newly diagnosed with DCIS on core biopsy prior to definitive surgery will be randomized to either a prepartion of broccoli sprout extract and mango juice or a placebo preparation of mango juice alone. All women will be on a cruciferous free diet for the duration of the study (14 days) and complete a daily dietary check list. Twelve hour urine collections and blood samples will be collected at various time points during the study. Acceptability of the 14 day dose will be evaluated by monitoring indices of compliance, including urinary measurements of ITC excretion, the daily food check list and a questionnaire administered at the end of the study.
