Foods and risk of bladder cancer: a case-control study in Uruguay

Eur J Cancer Prev. 2001 Oct;10(5):453-8. doi: 10.1097/00008469-200110000-00009.

Abstract

A case-control study on 144 cases of transitional cell bladder carcinoma and 576 hospitalized controls was conducted in Montevideo, Uruguay. Barbecued meat, salted meat and fried eggs were associated with significant increased risks of bladder cancer (odds ratio (OR) for high intake of salted meat 4.04, 95% confidence interval (CI) 2.24-7.27). On the other hand, all fruits, cooked vegetables, potatoes and cheese were associated with inverse associations (OR for high consumption of potatoes 0.38, 95% CI 0.23-0.64). The associations with salted and barbecued meat suggest that the way of preserving or cooking meat play a role in bladder carcinogenesis. More precisely, N-nitroso compounds and heterocyclic amines could be involved in this process.
