In this study, we sought to assess the epidemiology of GC, its clinicopathological profiles, and its association with risk factors as well as to identify premalignant gastric lesions (PGL) and examine neoplastic progression. (2) Methods: This five-year prospective study screened for GC and PGL in asymptomatic Saudi patients, aged 45\u201375 years (n = 35,640) and living in Al Kharj, Riyadh province in central SA. Those who were positive in a high-sensitivity guaiac fecal occult blood test (HSgFOBT+) and had negative results in colonoscopy offered to undergo upper GI endoscopy (n = 1242). Factors associated with GC were examined. (3) Results: The five-year participation rate was 87% (1080\/1242). The incidence rate of GC was 26.9 new cases per 100,000 population per year (9.6 new cases per year\/total population at risk\u201435,640), and it was 8.9 cases per 1000 persons per year among the 1080 subjects with HSgFOBT+ and negative colonoscopy results. The five-year mortality rate was 67% among patients with GC (n = 48), 3.0% among participants in the gastric screening program (n = 1080) and 0.09% among the original population participating in the colorectal screening program (n = 35,640). Intestinal-type adenocarcinoma was the most frequent type (77%), with the tumor most commonly located in the antrum (41%). Overall, 334 participants had PGL, and seven of them (2.1%) showed neoplastic progression to GC during the follow-up. Factors associated with GC were age, Helicobacter pylori (HP) infection, obesity (body mass index BMI &gt; 30), smoking, a diet of salty preserved foods, low income and a family history of GC. (4) Conclusions: The incidence of GC is low in central SA, but screening for PGL and GC among patients with HSgFOBT+ and negative colonoscopy may prevent or result in the early treatment of GC. HP eradication, normal body weight, not smoking and adhering to a healthy diet can reduce the risk of GC. The resulting data provide important input for the improvement of national guidelines.<\/jats:p>","DOI":"10.3390\/curroncol30090605","type":"journal-article","created":{"date-parts":[[2023,9,11]],"date-time":"2023-09-11T10:42:49Z","timestamp":1694428969000},"page":"8338-8351","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":17,"title":["Epidemiology, Risk Factors for Gastric Cancer and Surveillance of Premalignant Gastric Lesions: A Prospective Cohort Study of Central Saudi Arabia"],"prefix":"10.3390","volume":"30","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-2859-9188","authenticated-orcid":false,"given":"Georgios","family":"Zacharakis","sequence":"first","affiliation":[{"name":"Endoscopy Unit, Department of Internal Medicine, College of Medicine, Prince Sattam Bin, Abdulaziz University, PrinceSattam Bin Abdulaziz University Hospital, Al-Kharj 16278, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Abdulaziz","family":"Almasoud","sequence":"additional","affiliation":[{"name":"Department of Gastroenterology, Prince Sultan Military Medical City, Riyadh 11159, Saudi Arabia"},{"name":"Endoscopy Unit, Al-Kharj Military Hospital, Al-Kharj 11494, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Omar","family":"Arahmane","sequence":"additional","affiliation":[{"name":"Endoscopy Unit, King Khaled Hospital and Prince Sultan Centre for Health Care, Al-Kharj 11942, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4236-9389","authenticated-orcid":false,"given":"Jamaan","family":"Alzahrani","sequence":"additional","affiliation":[{"name":"Department of Family and Community Medicine, College of Medicine, Prince Sattam Bin Abdulaziz University, Al-Kharj 16278, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0506-0574","authenticated-orcid":false,"given":"Sameer","family":"Al-Ghamdi","sequence":"additional","affiliation":[{"name":"Department of Family and Community Medicine, College of Medicine, Prince Sattam Bin Abdulaziz University, Al-Kharj 16278, Saudi Arabia"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,9,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"6497","DOI":"10.1245\/s10434-022-12151-6","article-title":"GLOBOCAN 2020 report on global cancer burden: Challenges and opportunities for surgical oncologists","volume":"29","author":"Deo","year":"2022","journal-title":"Ann.
