Background : Colorectal cancer (CRC) oncogenesis is considered to be determined by interactions between genetic and environmental factors. Specific interacting factors that influence CRC morbidity have yet to be fully investigated. Patients and Methods : A multi-institutional collaborative study with 1511 CRC patients and 2098 control subjects was used to compare the odds ratios for the occurrence of polymorphisms at eleven known single nucleotide polymorphisms (SNPs) and performed GWAS study. TaqMan PCR and questionnaires were used to evaluate the effects of environmental exposures. Then, we performed microarray analysis of genes from cancer cells extracted from 110 primary tumors by laser microdissection. Results : Variants of rs6983267 on 8q24 were the most significant markers of risk for CRC (OR=1.16(1.06-1.27), p=0.0015). Non-insulin-dependent diabetes mellitus, a higher body mass index (BMI) at age 20 and meat consumption were environmental risk factors, whereas a tuna-rich diet and vitamin intake were protective factors. The cohort of rs6983267 SNP major (T) allele at 8q24 and diabetes had a 1.66 fold higher risk ratio than the cohort of major allele patients without diabetes. Meta-analysis of gene profiles (MetaGP) provide a clew to explain the risk for CRC in major allele at rs6983267 with diabetes mellitus. Conclusion : We confirmed that interactions between the genetic background and environmental factors are associated with increased risk for CRC. There is a robust risk of the minor G-allele at the 8q24 rs6983267 SNP, however, a major T-allele SNP could more clearly reveal a correlation with CRC specifically when diabetes mellitus is present. In addition, PICT1 gene, located on 19q13 (CRC oncogenic SNP), a p53 regulating gene, is associated with the progression of CRC and determined prognosis of CRC cases definitely.
