Gastric cancer represents a public health problem because of its high incidence. Survival of all types of cancer globally is estimated at 68.9% at 5 years, in contrast to gastric cancer where survival only reaches 32%. In our sample, some studies have found a 5-year survival rate of 10.6% (29) as opposed to countries where survival rates are 48.5%.Data collection was done by searching the records of the pathology service and the medical histories of the Central Military of personnel diagnosed with gastric adenocarcinoma in the Period between 2012 and 2015. The mean age was 59.3 years (59,3±18,12). The gender distribution was in men 74.5% and women 25.5%; by intestinal histological type 52%, diffuse 39.8% and mixed 8.2%; by stages, IV was the most frequent with 45.9%.The overall survival rate was 19%. The median overall survival was 18.2 months (95% CI of 11.5-24.8) and the survival rate for those younger than 60 years was estimated at 25% and 24% for those over 60 years old, analyzed at 4 years.The overall survival rate was 19% for the 48-month study period, lower than that reported for developed countries (The United States for 29%). The survival for the first and second year is similar to that for the study period. It´s can be explained by adequate treatment but a late diagnosis, since 77.5% of the patients in our study were in stages III and IV.
