Stomach cancer represents the fourth cause of mortality globally due to neoplasms. Objective: To update the diagnostic and therapeutic methods used in gastric adenocarcinoma through an evidence-based literature review that can serve as information for medical students and residents. Materials and methods: The research was carried out by means of a search of scientific articles on evidence-based medicine on the topic "gastric carcinoma" in Spanish and English in databases such as PubMed, Scielo, Elsevier, Cochrane, Redalyc, SpringerLink and Google Scholar, from which a selection was made of articles from high-impact journals categorized in quartiles 1 and 2. Conclusion: For the diagnosis of gastric cancer, it is of great importance to carry out promotion and prevention about the disease to the population, and establishing the risk and etiological factors for the development of gastric cancer, with an early diagnosis supported by performing imaging studies such as endoscopy in a preventive and screening manner.
