title: [Histologic and endoscopic characteristics of gastric cancer diagnosed in a national hospital of Callao, Peru].
abstract: OBJECTIVE
  To describe the histologic and endoscopic characteristics reported among patients diagnosed with gastric cancer in Daniel Alcides Carrion National Hospital in Callao.
  
  
  METHODS
  We performed a case series including all patients with histological diagnosis of gastric cancer from January 2009 to December 2011. Data were obtained from the registers of the pathology service of Daniel Alcides Carrion National Hospital. Factors such as age and gender of patients, histologic type, endoscopic location, presence of intestinal metaplasia, histologic degree, and cancer morphology were evaluated.
  
  
  RESULTS
  120 patients were included. Mean age was 65.4 ± 13.6 years; 59 (49%) were male. Based on the histologic type, intestinal type was found among 68 (56%); diffuse type among 45 (38%), and a mixed type in 7 (6%). Regarding the site, 23 (19%) of gastric cancers were located in the fundus; 52 (43%) in the body; 39 (33%) in the antrum, and 6 (5%) in the pylorus. Patients with gastric cancer of the intestinal type were in average older than those with a diffuse type (69.1 ± 10.3 versus 59.3 ± 15.3). 60.3% of intestinal-type gastric cancers were located proximally, versus 66.6% of diffuse-type cancers.
  
  
  CONCLUSIONS
  Among the studied population, diffuse-type gastric cancer appears at an earlier age than the intestinal type, and its most common location is proximal.
