Observational, descriptive, and retrospective study on 205 gastric laminated biopsies of patients who underwent an upper endoscopy at Hospital Nacional Arzobispo Loayza. The biopsies previously selected will be inspected by a Pathologist for the identification of microscopic characteristics of the Malgun (Korean word, means “clear”) cells, as well as the topographic, macro and microscopic characteristics of the biopsy, such as Helicobacter pylori infection, foveolitis, metaplasia, dysplasia, etc; using the modified Sydney classification as guide. In addition, the researchers will take microscopic photos at 40x magnification of all the H&E cases in which foveolitis and/or Malgun cell changes are present. Consequently, the biopsies with evidence of clear cells (Malgun) will be selected and immunohistochemically stained with p53 marker to confirm said results. Next, the researchers will tabulate positive cases and describe them through simple statistical methods (percentages). The Malgun cells characteristics will be detailed in both H&E/p53 staining matches. We believe it is a novel study to perform, given that clear cells or Malgun are a possible stage at diagnosis of gastric cancer and are not often the subject of other literature in the field. This study is relevant to contribute to the understanding of the Helicobacter pylori infection and its relation to gastric cancer pathogeny and because there are few studies about this topic.
