Gastric cancer is the one of the most frequent neoplasms of gastrointestinal tract.Regarding distribution, there is a rare incidence in people under 30, about 10% of patients are under 50; the average mean of patients is between 55 and 65 years. Males suffer more from this disease than females - 2:1 proportionally.The aim of this paper is to establish the importance of gastroscophy as a reliable method for gastric cancer diagnosis as well as to establish the importance of specific parameters (sex, macroscopic result) on survival of patients.This is a retrospective-prospective study. The study included 70 patients with gastric cancer or adenocancer diagnosis. The diagnosis was verified by gastroscophy and pathohistological result.Gastroscophy is a reliable method for gastric cancer diagnosis because early diagnosis is of great importance for survival of these patients. Tumor size, lymphnodaly status and pathohistological results are of great importance for the type of operative procedure to be applied and metastasis as well. Radical lymphodenoctomy with total or subtotal gastrectomy increases the survival rate.
