Abstract

Introduction: Breast cancer is the most frequent type of câncer in women, except for cases of non-melanoma skin cancer. It is the fifth cause of cancer death in general and the most common cause of cancer death in women.

Patients were selected through evaluation of Hospital Registry of Cancer.

Most of patients were stage II (30.5%) and had unspecified breast malignant neoplasm as primary site (93.68%). In this study, an overall survival of 85.13% was found.

Analysis of breast cancer survival in a northeastern Brazilian state based on prognostic factors: A retrospective cohort study

“…In the multivariate (adjusted) analysis, time to treatment after 60 days, stage IV, and triple-negative classification remained independent prognostic factors. The survival estimates observed in the study were lower than those found in some affluent areas of Brazil [ 22 – 24 ], as well as in high-income countries [ 25 , 26 ] and China (89.4%) [ 27 ].…”

Perfil Clínico E Epidemiológico De Pacientes Submetidas a Mastectomia No Norte De Minas Gerais, 2017-2022

“…Foi constatado que 74,4% dos pacientes tiveram acesso ao tratamento por meio do SUS. Estudos mostram que a sobrevida de pacientes que recorrem ao SUS é consideravelmente menor comparadas àquelas que tem acesso ao serviço privado por serem diagnosticadas tardiamente e se encontrarem com maior estadiamento no momento do diagnóstico, além da disparidade na qualidade de tratamento (Alvarenga et al, 2017;Cabral et al, 2019;Guerra et al, 2015). Este estudo demonstrou que o sistema público de saúde diagnosticou cerca de duas vezes menos pacientes no estágio 0-I (15% vs 33%) e duas vezes mais pacientes no estágio III (33% vs 16%) quando comparada à rede privada.…”
