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.
