Objetivo: identificar associações entre variáveis clínicas e sociodemográficas de mulheres com neoplasias malignas mamárias. Métodos: estudo ecológico e retrospectivo, conforme Standards for Quality Improvement Reporting Excellence. Participaram mulheres com neoplasias malignas mamárias (código C50) entre 2015 e 2021. Realizou-se análise descritiva, teste Qui-quadrado (α=5%) e Análise de Correspondência Simples entre idade, escolaridade, estado conjugal, raça, unidade federativa e estádio clínico pelo Sistema de Classificação de Tumores Malignos com dados dos Registros Hospitalares de Câncer. Resultados: houve associação entre estádios avançados e ensino fundamental incompleto, idade entre 30-59 anos e raça negra (p<0,005), enquanto maior grau de escolaridade e Unidade Federativa de tratamento localizada nas regiões Sul e Sudeste associam-se a estádios iniciais. Conclusão: neoplasias mamárias em mulheres brasileiras apresentam estadiamento avançado entre mulheres negras, com menor escolaridade e tratadas no Norte e Nordeste. Contribuições para a prática: é necessário diagnóstico precoce especialmente para mulheres com menor escolaridade, idade >30 anos, no Norte e Nordeste.
Objective: to identify associations between clinical and sociodemographic variables among women with breast cancer. Methods: ecological, retrospective study conducted in accordance with the Standards for Quality Improvement Reporting Excellence. Records from women with breast cancer (ICD-10 code C50) diagnosed between 2015 and 2021 were included. Descriptive analysis, chi-square tests (α = 5%), and simple correspondence analysis were performed to examine associations among age, educational attainment, marital status, race/skin color, state, and clinical stage, using Hospital-Based Cancer Registry data. Results: advanced-stage disease was associated with not completing elementary school, age 30–59 years, and being classified as Brown or Black (p < 0.005), whereas higher educational attainment and treatment in states located in the South and Southeast Regions were associated with early-stage disease. Conclusion: breast cancer in Brazilian women was more often diagnosed at an advanced stage among Brown and Black women, those with lower educational attainment, and those treated in the North and Northeast Regions. Contributions to practice: early diagnosis is especially needed for women with lower educational attainment, those aged 30 or older, and those in the North and Northeast Regions.
