OBJECTIVE Incidence of esophageal cancer varies among countries, with differences found particularly between developed and less-developed regions. The aim of the present study was to investigate differences in incidence between the Eastern Anatolia Region (EAR) and the Eastern Black Sea Region (EBSR). METHODS Data were obtained from the databases of the EAR (1996-2010) and the EBSR (1999-2013). A total of 47 patients from the EBSR and 135 patients from the EAR were included. RESULTS Higher incidence of esophageal cancer was found in the EAR, compared to the EBSR. In the EAR, overall survival was 20 months, median survival was 13 months, and 1-, 3-, and 5-year survival rates were 51.3%, 20.1%, and 13.4%, respectively. Following termination of treatment, overall survival was 18 months in the EBSR, median survival was 12 months, and 1-, 3-, and 5-year survival rates were 52.5%, 10.9%, and 6.6%, respectively. CONCLUSION A significant difference was found between regions regarding incidence of esophageal cancer. This cancer may be prevented through public education and awareness. Programs that promote prevention must be implemented worldwide, particularly in the EAR.
