Cruciferous Vegetables, Bioactive Metabolites, and Microbiome for Breast Cancer Prevention

Area of Science:

• Oncology
• Nutritional Science
• Microbiome Research

Background:

• Breast cancer is a complex disease with diverse subtypes and treatment responses.
• Cruciferous vegetables contain bioactive compounds like sulforaphane (SFN) and indole-3-carbinol (I3C)/3,3'-diindolylmethane (DIM) with potential anti-cancer properties.

Purpose of the Study:

• To review recent human and preclinical studies on the efficacy of SFN, I3C, and DIM in breast cancer.
• To explore the role of the gut microbiome in modulating the effects of cruciferous vegetables and breast cancer treatments.
• To identify promising combination therapy strategies involving phytochemicals and conventional treatments.

Main Methods:

• Systematic review of human studies (up to 2024) on SFN, I3C, and DIM in breast cancer risk, prognosis, and treatment.
• Review of preclinical studies (2018-2024) assessing the synergistic effects of phytochemicals with standard therapies.
• Analysis of research on the gut microbiome's influence on glucosinolate metabolism and breast cancer outcomes.

Main Results:

• Recent human studies indicate potential benefits of SFN, I3C, and DIM in breast cancer management.
• Preclinical data suggest promising synergistic effects when combining these phytochemicals with conventional treatments.
• Interindividual variations in gut microbiome composition can impact the metabolism of cruciferous vegetable compounds and treatment efficacy.

Conclusions:

• Integrating cruciferous vegetables and their bioactive compounds, considering individual microbiome profiles, offers a promising complementary strategy for breast cancer care.
• Personalized approaches that account for microbiome-host interactions may enhance the benefits of dietary interventions and standard treatments.
• Further clinical trials are warranted to validate these combination therapy strategies.
