Abstract

Background: Gastric cancer is the second cause of cancer death worldwide and the first cause in Chile. Management of this pathology is controversial. Aim: To report the results on morbidity, mortality, and long-term survival rates of surgical treatment of gastric cancer, and compare them with those reported in the literature. Material and Methods: Follow up of 423 patients (aged 16 to 88 years, 271 males) operated for a gastric adenocarcinoma between 1996 and 2002. Patients were staged with the 5th edition of TNM staging system, and the 2nd edition in English of the Japanese Classification of Gastric Cancer.
