Abstract

BACKGROUND:

Genetic predispositions to disease have focused on highly penetrant causative changes in tumor suppressor genes or genes associated with DNA mismatch repair. New investigations are revealing new genetic associations with disease that are more subtle in their association with disease and require characterization.

METHODS:

In this report we have examined the tumor characteristics in a group of patients who have been shown to harbor two polymorphisms in two genes that are associated with the immune system NOD2 and TNFalpha.

RESULTS:

Colorectal cancers from patients with NOD2 3020insC and TNFalpha-1031T/T constitutional changes are mostly right-sided disease (OR=2.21, p=0.03) with a tendency to higher stages (OR=2.41, p=0.06), increased number of associated polyps (OR=1.77, p=0.16) and later age of average age of disease onset (p=0.039).

CONCLUSION:

The results reveal that there appear to be specific characteristics associated with the tumors that may aid in determining management strategies to reduce the risk of disease.
