Abstract
The gastric juice of patients with atrophic gastritis from the high-risk gastric cancer region of Nariño, Colombia, was analyzed for nitrate, nitrite, and thiocyanate content. Patients whose gastric juice pH is greater than 5 have significant elevation of nitrite values. The possible role of nitrite in gastric carcinogenesis is discussed.
