This is a descriptive observational study of patients upon whom esophagogastroduodenoscopies had been performed at the hospital Universitario de La Samaritana from 2004 to 2009 and who had been diagnosed histologically with Gastric Cancer (GC). 259 cases, 153 men and 106 women, with average ages of 66 years were included. A very high proportion of patients (40%) who had sought medical assistance because of di- gestive hemorrhaging were ultimately diagnosed with GC. 97% of these cases had advanced tumors with Bormann levels III and IV being the most common (72% and 16% respectively). A large percentage of patients (53%) had diffuse intestinal adenocarcinomas. Proximal locations of these tumors in the cardia, fundus, cor- pus) predominated (56.4%) especially among male patients (65%). The majority of these patients (69.4%) came from regions of the department of Cundinamarca located more than 2,000 meters above sea level. Early detection programs for GC need to be established in regions of high incidence.
