Özet
Aim: In developed countries, there has been a recent increase in the prevalence of adenocarcinoma of the esophagus and cardia, along with a decrease in distal gastric cancers. Little is known regarding the prevalence of these diseases in developing countries. The aim of the present study was to evaluate changes in the prevalence of gastric adenocarcinomas in Turkey as a function of anatomic location. Methods: Data were retrospectively collected from 16 centers from January 1990 to December 2000. Owing to the exclusion criteria, a total of 4065 cases of tumors of the stomach and distal esophagus were included. Tumors localized to the body, the antrum and pyloric channel were considered distal cancers. Helicobacter pylori (H. pylori) was also detected. Results: Patients' mean age was 60.7 +/- 9 years, with a male : female ratio of 68:32. The ratio of distal/proximal adenocarcinoma was 2:1 for the western part of Turkey and 3:8 for the eastern part of the country (P < 0.0001), and this did not change during the 11 years. H. pylori was detected significantly less in the west compared to the east for distal tumors (65.7 vs 38.7%, respectively, P = 0.02). Conclusion: In Turkey, a developing country with a high H. pylori prevalence, contrary to the state of developed countries, the ratio of distal versus proximal gastric adenocarcinomas has not changed. Geographical distribution should be taken into the account in projecting the changing patterns of gastric cancers.
