ABSTRACT
ABSTRACT

Objective:

to analyze the overall survival and prognostic factors of women with breast cancer in the city of Goiânia.

Methods:

this is a retrospective, cross-sectional, observational study that included women with malignant neoplasms of the breast identified by the Goiânia Population-based Cancer Registry. The variables studied were age at diagnosis, tumor size, staging, axillary lymph node involvement, tumor grade, disease extent, hormone receptors, and c-erb-B2 oncoprotein. We performed overall survival analyzes of five and ten years.

Results:

we included 2,273 patients in the study, with an overall survival of 72.1% in five years and 57.8% in ten years. In the multivariate analysis adjusted for tumor size, the factors that influenced the prognosis were axillary lymph nodes, histological grade, progesterone receptor, c erb B2, T staging and disease extension.

Conclusion:

overall survival in ten years is below that observed in other countries, and possibly reflects what happens with the majority of the Brazilian population. The prognostic factors found in this population follow the same international patterns.
RESUMO
RESUMO

Objetivo:

analisar a sobrevida global e os fatores prognósticos de mulheres com câncer de mama na cidade de Goiânia.

Métodos:

estudo observacional, retrospectivo, transversal, que incluiu mulheres portadoras de neoplasias malignas da mama identificadas pelo Registro de Câncer de Base Populacional de Goiânia. As variáveis estudadas foram idade ao diagnóstico, tamanho do tumor, estadiamento, comprometimento dos linfonodos axilares, grau tumoral, extensão da doença, receptores hormonais e oncoproteína c-erb-B2. Foram realizadas análises de sobrevida global, de cinco e de dez anos.

Resultados:

foram incluídas no estudo 2273 pacientes, com sobrevida global em cinco anos de 72,1% e de 57,8% em dez anos. Na análise multivariada ajustada pelo tamanho do tumor, os fatores que influenciaram o prognóstico foram linfonodos axilares, grau histológico, receptor de progesterona, c-erb-B2, estadiamento T e extensão da doença.

Conclusão:

a sobrevida global em dez anos está abaixo da observada em outros países, e possivelmente reflete o que acontece com a maioria da população brasileira. Os fatores prognósticos encontrados nesta população seguem o mesmo padrão internacional.
