Purpose: There have been studies on the relations between metabolic syndrome and colorectal cancer or on the relations between methylenetetrahydrofolate reductase (MTHFR) polymorphism and colorectal cancer, but reports on the relationship between metabolic syndrome, MTHFR polymorphism and colorectal cancer all together are rare. The aim of this study is to find the interrelation between metabolic syndrome and MTHFR polymorphism in colorectal cancer.
Methods: This study investigated 255 colorectal cancer patients (cancer group) who underwent surgery in our hospital from March 2003 to December 2008 and compared those patients to 488 healthy patients (control group). The diagnostic criterion for metabolic syndrome was based on the National Cholesterol Education Program-Adult Treatment Panel III (NCEP ATP III), and the MTHFR 677 polymorphism was analyzed.
Results: When colorectal cancer patients and patients in the control group were classified as MTHFR 677 subtypes, there was no difference between the two groups: CC 87 (34.1%), CT 134 (52.6%), and TT 34 (13.3%) for the cancer group and CC 145 (32.4%), CT 238 (53.1%), and TT 65 (14.5%) for the control group. Distributions of MTHFR 677C/T genotype and allele frequencies in the individuals with and without metabolic syndrome in the cancer group showed no differences. Moreover, we could find no differences in distributions of MTHFR 677C/T genotypes in the clinical and the biomedical variables of individuals with and without metabolic syndrome in the cancer group.
Conclusion: Our results show no relation between metabolic syndrome and MTHFR polymorphism in colorectal cancer. However, a further prospective study, based on a precise diagnostic criterion for metabolic syndrome, is needed.
