What is it about?
We performed a case-control study of 158 bladder transitional cell carcinoma (TCC) cases and 316 controls to investigate the association between methylenetetrahydrofolate reductase (MTHFR) C677T, A1298G, and G1793A polymorphisms and bladder cancer susceptibility by polymerase chain reaction restriction fragment length polymorphism (PCR-RLFP) technique.

Why is it important?
Bladder cancer incidences vary significantly worldwide, suggesting that there is a variation in individual susceptibility to develop bladder cancer in the general population. The lowest incidence rate is in Eastern Europe and many parts of Asia and the highest in North America and Western Europe. Bladder cancer has multifactorial etiology, including interactions between genetic background and environmental factors. Tobacco smoking is one of the strongest known risk factors for bladder cancer, accounting for 50% of cases in men and 35% in women. More than 60 carcinogens have been described in cigarette smoke. Among these are oxidants and highly reactive free radicals. Vitamin B12 is a strong antioxidant. High intakes of folate and B vitamins (B12, B6, and B2) are associated with significant decreases in bladder cancer risk.
