Piecing together the risk factors for stomach cancer
Pepsinogen is a precursor of pepsin, a protease secreted in stomach, and is immunologically categorized into two main classes, pepsinogen I and pepsinogen II. Pepsinogen I exists in fundic gland mucosa, while pepsinogen II exists more broadly, in organs including fundic gland mucosa, cardiac glandpyloric gland, duodenal gland.1 Pepsinogen I value and pepsinogen I / pepsinogen II ratio both correlate with extent of the fundic gland area expansion, and it is useful as a marker of chronic atrophic gastritis progression. Atrophic gastritis progressions is strongly related with stomach cancer,2 and those with severe atrophic change have higher frequency of cancer being found.3-4
Lumipulse® G Pepsinogen I and II
Lumipulse G Pepsinogen I and II are assay systems, including a set of immunoassay reagents, for the quantitative measurement of pepsinogen I and II in specimens based on CLEIA technology by two-step sandwich immunoassay method on the LUMIPULSE G system (LUMIPULSE G600II and LUMIPULSE G1200). The assays utilise proven CLEIA (ChemiLuminescent Enzyme Immunoassay) technology with results that are available in 30 minutes.
