Introduction: Morphological alterations of the gastric mucosa that predispose to the development of gastric cancer are atrophy, metaplasia and dysplasia. Various etiologic factors have been studied, especially in first degree relatives,with a probability of gastric cancer double than that of the general population. Objective: To diagnose premalignant gastric lesions in relatives of patients with gastric cancer evaluated in the Gastroenterology consultation of „Hospital Vargas de Caracas‰ and „Hospital Militar Dr. Carlos Arvelo‰. Patients and Methods: A descriptive, prospective, longitudinal study was made, from October 2008 to May 2009. We included 75 individuals aged 18 to 80 years in first degree relatives of patients with gastric cancer, who underwent upper gastrointestinal endoscopy with biopsy guided. Results: We found 51 (68%) female and 24 (32%) male, with these endoscopic findings: normal in 52% of the patients, with chronic gastropathy 37, 33%, gastric ulcer in 5,3%, gastric polyps in 3,33% and duodenal ulcer in 1,33%. The histological study found that atrophy was present in 25 (33.3%) patients, intestinal metaplasia in 17 (22, 67%) and dysplasia in 4(5, 33%) and 1(1,33%) indefinite to dysplasia. Conclusion and recommendation: In this group of patients it was found a 42.6% of premalignant gastric lesions, of which 5.33% corresponded to dysplasia. Neither one had endoscopic malignant lesions. We recommend as a routine in all Gastroenterology Divisions in the country a program of screening in first degree families of patients of gastric cancer
