Dietary phytoestrogens, like genistein, may influence hepatocellular carcinoma (HCC) risk. Lower genistein intake was observed in HCC patients compared to cirrhosis patients, suggesting a potential role in HCC development.

Area of Science:

  • Nutritional Science
  • Hepatology
  • Oncology

Background:

  • Phytoestrogens, plant compounds mimicking estrogen, are hypothesized to have a protective role against cancers.
  • Estrogen receptors are implicated in hepatocellular carcinoma (HCC) pathogenesis, suggesting dietary estrogenic substances may influence risk.
  • Previous research has explored phytoestrogen roles in breast and prostate cancer, but their impact on HCC requires further investigation.

Purpose of the Study:

  • To investigate the association between dietary phytoestrogen intake and the risk of developing hepatocellular carcinoma (HCC).
  • To compare the dietary habits and phytoestrogen consumption of patients diagnosed with cirrhosis versus those with HCC.

Main Methods:

  • A case-control study involving 92 cirrhotic patients and 32 HCC patients at initial diagnosis.

  • Dietary intake over the past year was reconstructed through interviews conducted by a dietician using questionnaires and food portion images.
  • Phytoestrogen content of food, beverages, and seasonings was analyzed using the Winfood database.

    • Main Results:

    • No significant differences in total caloric or macronutrient intake were found between cirrhosis and HCC groups.
    • Patients diagnosed with HCC showed significantly lower intake of genistein compared to cirrhotic patients.
    • Intake of lignans was linked to wine consumption; differences were significant only when alcohol intake was considered.

    Conclusions:

    • Dietary intake of specific phytoestrogens, particularly genistein, differs between cirrhotic patients and those with HCC.
    • Lower genistein intake in HCC patients may be attributed to personal dietary preferences.
    • These dietary differences in estrogen-like substances could play a role in modulating HCC risk among cirrhotic patients.
