Introduction: Based on differences in the rates of incidence and mortality in gastric  cancer (GC) and cancer colorrectal (CCR) in the world, even in the same country, compared the prevalence among these tumors, a geographical area of high risk. Materials and  methods:  an analytical prevalence study  was  conducted including patients  over 18  years  old who underwent upper endoscopy and colonoscopy, between January 1996  and April 2015,  which had cancer, histological confirmation of adenocarcinomas of gastric or colorectal endoscopic diagnosis and which were sporadic tumors. Results: A total of 131.490 (109.034  upper digestive endoscopy and 22,456  colonoscopies) endoscopy procedures were performed. We met a total of 1982  cancers, of whom 1562 were CG (78.8  percent) and 420  were CCR (21.2%). The CG was more frequent in men (68.75%) and CRC in women (51.43%), with similar average ages  in both. Conclusion: This study found that the advanced with respect to advanced colorectal cancer, gastric cancer ratio is 4:1 respectively.
