Gastric cancer is associated with NOS2 -954G/C polymorphism and environmental factors in a Brazilian population.

ABSTRACT:

Background

Gastric cancer can progress from a chronic inflammation of the gastric mucosa resulting from Helicobacter pylori infection that activates the inflammatory response of the host. Therefore, polymorphisms in genes involved in the inflammatory response, such as inducible nitric oxide synthase (NOS2), have been implicated in gastric carcinogenesis. The aim of this study was to evaluate the association of NOS2 polymorphisms Ser608Leu (rs2297518) in exon 16, -954G/C and -1173C/T, both in the promoter region, with gastric cancer and chronic gastritis and the association of cancer with risk factors such as smoking, alcohol intake and H. pylori infection.

Methods

We conducted a population-based case-control study in 474 Southeast Brazilian individuals (150 with gastric canc
