Is allele 2 of the interleukin-1 receptor antagonist gene associated with early gastric cancer?
The genotype IL-1RN*2/2 seems to be associated with early-stage gastric cancer. As opposed to advanced-stage gastric cancer, further proinflammatory cytokine polymorphisms were not associated independently, but might act in combination and mirror early steps of gastric carcinogenesis in hosts colonized by Helicobacter pylori. However, these findings await confirmation in future trials and should be underscored by gene expression studies.
Once high-grade bladder outlet obstruction induces C-fiber-related DO, it is strongly suggested that this process, together with nocturnal polyuria, plays an important role in the consequent clinical manifestations of nocturia in patients with lower urinary tract symptoms.
