Study to Evaluate the Effect of Sulforaphane in Broccoli Sprout Extract on Breast Tissue

Breast Cancer Clinical Trial

Official title:
Evaluating the Effect of Broccoli Sprouts (Sulforaphane) on Cellular Proliferation, an Intermediate Marker of Breast Cancer Risk

Clinical Trial Summary

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.

Clinical Trial Description

A double-blind randomized Phase II chemoprevention trial of BSE versus placebo will be conducted in up to 35 women diagnosed with DCIS on core biopsy prior to their definitive surgery (study diagram below). The primary study endpoint will be a decrease in the mean proliferative rate measured by Ki67%.

Women diagnosed with DCIS on core or incisional/excisional biopsy scheduled for definitive surgery at Johns Hopkins Hospital will be recruited for this study. Participants will be placed on a cruciferous free diet for the 14 days prior to their surgical date and drink a randomized intervention beverage (mango juice with or without broccoli sprout extract). Additionally participants will provide 2 blood and 2 urine sample collections, report medication use and adverse events using prepared forms and complete a daily diet check list during the 14 day intervention. On the day of definitive breast surgery, 1-2 grams of breast tissue (including normal adjacent breast tissue) will be collected during surgery. ;
