This study was designed to examine changing trends in localization of gastric cancer in Turkey in recent years. Materials and Methods: A total of 796 adult patients with newly diagnosed, histologically proven adenocarcinomas, treated and followed up at our oncology center between 2000-2011, were examined retrospectively. In all cases tumor localization were identified and recorded with clinicopathological features. Results: The median age was 58 with a range between 22-90 for the 552 men and

... women. Median follow up was 12 months (1-276) and median overall survival was also 12 months (11.5-12.4). There was a trend for a change in tumor localization from distal to proximal. Survival of patients was low with advanced T and N stage tumours. Positive surgical margins, lymphovascular invasion, perineural invasion, cardioesophageal localization were predisposition factors for metastatic disease in gastric cancer. There was no relation between age or sex and histopathological type of gastric cancer. Conclusions: There is a trend in our country for a change in gastric tumour localization from distal to proximal, with clear significance for treatment choices.
