Hypothesis

Does the intake of meat-derived mutagens and cooking methods increase the risk of renal cell carcinoma?

Conclusion

Intake of benzo(a)pyrene from barbecued meat is associated with an increased risk of renal cell carcinoma.

Supporting Evidence

  • Barbecued meat intake was positively associated with renal cell carcinoma risk.
  • Benzo(a)pyrene intake was significantly higher in cases compared to controls.
  • The risk of RCC increased with higher intake of benzo(a)pyrene.
  • Associations varied by race, with African Americans showing a more pronounced risk.
  • Broiled meat intake was inversely associated with RCC risk.

Takeaway

Eating a lot of barbecued meat can make you more likely to get kidney cancer.

Methodology

A population-based case-control study with 1192 cases and 1175 controls, using a Diet History Questionnaire to assess meat intake and cooking methods.

Potential Biases

Potential for selection and non-response bias due to differential participation rates among cases and controls.

Limitations

Self-reported data may introduce recall bias, and the study may not account for all dietary sources of benzo(a)pyrene.

Participant Demographics

Caucasian and African American men and women aged 20-79 years.
