Evolução temporal dos estádios do câncer de mama ao diagnóstico em um registro de base populacional no Brasil central

Resumo

PURPOSE: To analyze the temporal changes of breast cancer staging at diagnosis among women living in Goiânia, Goiás, Brazil, between 1989 and 2003. METHODS: Retrospective and descriptive study in which the cases were identified from the Population-Based Cancer Registry of Goiânia for the period from 1989 to 2003. The variables studied were age, diagnostic method, topographic sublocation, morphology and breast cancer staging. Frequency analyses were carried out on the variables and means, and the medians for the age were determined. The SPSS ® 15.0 software was used for statistical analyses. RESULTS: A total of 3,204 breast cancer cases were collected. The mean age was 56 years (sd±16 years). With regard to clinical staging, 45.6% of the cases were found to be localized in the breast, with an increased rate of 19.25% between the first and the third five-year period (p<0.001; CI 95%=0.14- 0.23) and 10.2% of cases were with distant metastases. However, a reduction of 17.74% for metastatic cases in the same interval (p<0.001 e CI 95%=0.14-21) was observed. The in situ case rate was 0.2% in 1989-1993 and increased to 6.2% in 1999-2003 (p<0.001, IC95%=4.9-7.4). CONCLUSION: The diagnostic profile of breast cancer in the city of Goiânia is changing. Substantial increases in the number of early breast cancer cases are being found in relation to the number of advanced cases.
