Introduction and aim: Gastic cancer is the most frequent neoplasia of the digestive tract worldwide. Incidence rates vary according to the region or country analyzed. Variation in the different regions of Mexico is attributed to very specific dietary, environmental, and genetic patterns. The aim of the present work was to carry out an epidemiologic analysis of the cases of gastric cancer treated at the Hospital Regional de Alta Especialidad 'Ciudad Salud', located in Chiapas, Mexico.
Material and methods: A descriptive, ambispective, longitudinal study was conducted. Cases of gastric cancer were searched for in the database from the oncology service of our hospital, that were treated within the time frame of 2007 to 2014. The data obtained were analyzed using the SPSS v. 20 statistics program.
Results: A total of 100 cases of gastric cancer were detected, 84 of which were included in the study. Forty-one of the cases were men, 43 were women, and their mean age was 57.3 years. Incidence was 2.14 for every 100 oncology patients released from the hospital. Of the study patients, 35.71% stated they had been alcoholics, 22.61% were smokers, and 90.16% were diagnosed with adenocarcinoma. At the end of follow-up, 18 of the study patients had died.
Conclusion: The results of the present epidemiologic analysis showed that the consumption of alcohol and tobacco played an important role in the development of gastric cancer in the patients studied, as well as having a family history of any type of cancer. Because gastric cancer is usually diagnosed in advanced stages, it would be reasonable to formulate a strategy for the prevention, early detection, and control of the disease in the State of Chiapas, Mexico.
