UNASSIGNED: 4254 Background: @entity356 is one of the most frequent @entity5 of the gastrointestinal tract in the Middle East region. Remarkable differences in clinical and pathological features, and the outcome of the disease are observed between countries which lead to define the cases as western and eastern types of @entity356 . However, the place of the Turkish @entity1 in this spectrum is not well defined. METHODS: In this retrospective single center study we aimed to analyze the characteristics and outcomes of Turkish @entity1 with @entity5 . RESULTS: 683 @entity1 (409 males, 274 females; m/f :1.49) were included. Mean age of diagnosis was 57.4    12 years. Anatomical localization of the @entity5 were as follows; antrum 44.1%; corpus 26.9%; @entity418 12.7%; diffuse 15.7%; pylorus 0.6%. At the initial diagnosis only 2.6% of the @entity1 had stage I disease, 8% had stage II, 37. 4% had stage III, and 50.2% had stage IV disease. All the @entity1 had histologically proven @entity420 , 41% were poorly differantiated, 41.6% were moderately differantiated, 12.7% were well differantiated, and 4.7% were @entity5 . Median survival times of the @entity1 were in stage I 52 months, in stage II 42.4 months, in stage III 33.9 and in stage IV 9.8 months. CONCLUSION: . The mean age of Turkish @entity1 are younger and the incidence of @entity5 are still much more @entity5 like the other middle-east countries. But the survival rates according the stage of the disease is different from other middle-east countries with poor survival rates and worse prognosis. High incidence of advanced stages of the disease suggests that screening programs are needed especially in east Anatolian regions of @entity233 for early detection. In conclusion Turkish @entity1 do not belong either to the easten type or the western type @entity356 and show some features of both forms of the disease. No significant financial relationships to disclose.
