Article Abstract
A retrospective cohort study was carried out aiming to evaluate the survival of 655 women with breast cancer, seen in the Single Health System, Joinville, Santa Catarina, Brazil. For the analysis of survival, the method of Kaplan-Meier and Cox model was applied. The survival according to the staging of women was significantly different in accordance with the results of the test of Log-rank Test. The rate of risk of instantaneous death between the stages I/II, I/III and I/IV was 3.26, 15.40 and 25.51, respectively. These findings are in consonance with literature data, and indicate that the staging is a variable that explains the differences in the survival among women with breast cancer.

Background: The online nature of decision aids (DAs) and related e-tools supporting women's decision-making regarding breast cancer screening (BCS) through mammography may facilitate broader access, making them a valuable addition to BCS programs.
Objective: This systematic review and meta-analysis aims to evaluate the scientific evidence on the impacts of these e-tools and to provide a comprehensive assessment of the factors associated with their increased utility and efficacy.
Methods: We followed the 2020 PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines and conducted a search of MEDLINE, PsycINFO, Embase, CINAHL, and Web of Science databases from August 2010 to April 2023.

Mammography is one of the main methods available for breast cancer screening in Brazil. However, differences in timely access and performance of the exam can be highlighted based on social determinants of health, considered relevant due to their influence on the health situation of a population. Thus, the present study aimed to identify the social determinants of health associated with access to and performance of mammography in Brazilian women.

This article aims to identify the relationship between material deprivation and mortality from breast, cervical, and prostate neoplasms in the Brazilian adult population and the relationship between ethnicity/skin color and material deprivation. This cross-sectional ecological study calculated the mean mortality rate per 100,000 inhabitants, and deaths were standardized by age and gender and redistributed per to ill-defined causes, stratified by age group and ethnicity/skin color. We applied the Negative Binomial model, containing the interaction between ethnicity/skin color and the Brazilian Deprivation Index (IBP).

A recent publication by Bornes and colleagues explored the impact of the estrous cycle on mammary tumor response to neoadjuvant chemotherapy (NAC). Using genetically engineered mouse models, Bornes and colleagues revealed that chemotherapy is less effective when initiated during the diestrus stage compared to during the estrus stage. A number of changes during diestrous were identified that may reduce chemosensitivity of mammary tumors: an increased mesenchymal state of breast cancer cells during diestrous, decreased blood vessel diameters, and higher numbers of macrophages in the tumor microenvironment.
