Abstract
Homocysteine is an amino acid generated metabolically by the S-adenosylmethionine-dependent transmethylation pathway. In addition to being a well-known independent risk factor for coronary heart disease, is also a risk factor for cancer. Patients suffering from inflammatory bowel diseases (IBD) including ulcerative colitis and Crohn’s disease are at increased risk of developing colorectal cancer in comparison to healthy individuals. Furthermore, the risk of hyperhomocysteinaemia is significantly higher in IBD patients when compared with controls. In the present article, we review the mechanisms in which hyperhomocysteinemia may contribute to increased risk of colorectal cancer in IBD patients.
Core tip: There is growing evidence suggesting hyperhomocysteinemia to be associated with increased colorectal cancer risk. Taking this into account that hyperhomocysteinemia and its related contributors are prevalent among patients with inflammatory bowel disease, we suggest performing well designed epidemiological, experimental, and clinical trial studies to investigate such association in these patients.
