OBJECTIVE: In this study, we aimed to determine the significance of the staging systems (EORTC, De Groot, MACIS, and @entity2802 ) on the prognosis of @entity259 @entity1 who underwent surgery in our clinics. MATERIAL AND METHODS: This retrospective study included 181 @entity1 who were operated between December 1995-December 2007, with a diagnosis of @entity259 . In order to obtain data related to @entity5 staging, a computer program for @entity2461 was developed to facilitate parameter recording. Survival analysis was performed. The findings were compared to the predicted rates by the staging systems. RESULTS: According to the De Groot staging system, stage 1 and stage 2 @entity1 ' results were compatible, but stage 3 and 4 @entity1 ' results were different (stage 3; 87% versus 66.6%, stage 4; 35% versus 100%, p=0.04). In the MACIS staging system, 20-year survival rates are determined and comparison should not be made due to insufficient follow-up period in this study. When compared to the EORTC staging system, stage 3 and stage 4 @entity1 ' results were determined different (stage 3; 51% versus 100%, stage 4; 33% versus 50%, p=0.02). The most consistent results in terms of prognosis was determined in comparison with the @entity2802 staging system (stage 1; 100% versus 97.8%, stage 4; 45.3% versus 50%). CONCLUSION: Many classification systems are proposed for @entity259 , to predict the behavior of the @entity5 . In this study, we concluded that for determination of prognosis in @entity259 , the @entity2802 staging system could best predict prognosis consistent with clinical findings.
