These results, also in view of the interactions found between some SNPs and fish consumption and NSAID use, reinforce the importance of the role of the AA pathway in colorectal tumorigenesis, and indicate that some of these modifying alleles might contribute to a proportion of sporadic colorectal cancer cases, although the exact underlying mechanisms involved are not understood yet.
