Introduction: Esophageal cancer is a malignancy of high mortality worldwide. Studies on Population-based of this neoplasm in Brazil are scarce. In the central-western of Brazil there are population-based cancer registries to monitor the impact of cancer. However there are no studies describing the profile of this tumor in the central-western of Brasil. Another reason for this study is the large-scale of internal migration happened in the 70's from Porto Alegre to the central-western. Such migration may have influenced the incidence and mortality rates of esophageal cancer in the region. Objective: To evaluate the performance of the Population-Based Cancer Registry of Goiânia (PBCR of Goiânia) in the collecting of basic variables and recommended variable (clinical staging) of incident cases of esophageal cancer. To describe the epidemiological profile of the incidence, mortality and trends esophageal cancer in central-western Brazil. Methods: From the PBCR of Goiânia it was analyzed the completeness of variables related to the patient, tumor and clinical staging of esophageal cancer cases for incidence analysis the period were: Cuiabá (2000-2005), Brasília (1999-2002) and Goiânia (1995-2008). Mortality data were obtained from DATASUS (2010) for the period 1980-2008 for all capitals of central western region. For statistical analysis we used version 15.0 of SPSS for Windows ®, the X2 test and odds ratios were calculated by applying significance at p<0.05 and Joinpoint Regression Program for trend analysis. Results: In the period from 1988 to 2008 were reported 827 cases of esophageal cancer in Goiania in a 3:1 ratio (men/women). Most cases were diagnosed in advanced stages. The analysis of variables collected by RCBP Goiânia identified indices of good completeness of the basic variables related to the patient and tumor, whereas for clinical staging was low (5%). The highest incidence of esophageal cancer in the center-western of Brazil was observed in Cuiabá and lowest in Goiania, while rates in women were similar in Brasilia and Cuiaba. The mortality rates have a heterogeneous increase trend among men in Cuiaba and Campo Grande and among women in Goiania. Conclusions: The RCPB Goiânia had a good performance in collecting of basic variables of esophageal cancer, and low for clinical staging. The profile of incidence of esophageal cancer in the central-western of Brazil was higher in Brasilia and Cuiaba, with incidence rates for men similar to those of Porto Alleger in some periods. There was an increased in mortality in men in Cuiaba and Campo Grande and among women in Goiania. Long-term studies may confirm the influence of migration on the incidence rates of esophageal cancer in this region.
