Abstract

BACKGROUND:

Breast cancer is commonly diagnosed at an advanced stage in Brazil.

AIM:

Analyze the determinants of advanced staging in Brazilian women with breast cancer.

METHODS:

Crosssectional study, including women diagnosed with breast cancer in Brazil, between 2000 and 2009.

RESULTS:

A total of 59,317 women were included, 53.5% being classified as advanced stage (≥IIB). Younger age (18 to 49 years old) (OR=1.61 95% CI 1.51 to 1.72) or between 40 and 49 years old (OR=1.08 95% CI 1.03 to 1.14), having low educational level (OR=1.53 95% CI 1.48 to 1.58), living in less developed geographical regions (OR=1.27 95% CI 1.21 to 1.33), having invasive ductal carcinoma (OR=2.70 95% CI 2.56 to 2.84) and invasive lobular carcinoma (OR=2.63 95% CI 2.42 to 2.86) were associated with advanced breast cancer.

CONCLUSION:

We conclude that future interventions should focus on these high risk groups.
