Koh WP, Yuan JM, van den Berg D, et al. Interaction between cyclooxygenase-2 gene polymorphism and dietary n-6 polyunsaturated fatty acids on colon cancer risk: the Singapore Chinese Health Study. Br J Cancer. 2004;90(9):1760-4.
This case-control study of 310 colorectal cancer cases and 1177 controls in a nested prospective, population-based cohort of Singapore Chinese subjects found a statistically significant association between the cyclooxygenase (COX)-2 -765G>C gene polymorphism and colon cancer risk among high consumers of dietary n-6 polyunsaturated fatty acids
(odds ratio=2.38, 95% confidence interval=1.23-4.59).
