Abstract

Background: Breast cancer mortality is increasing in Brazil. This study examines the impact of sociodemographic factors, screening procedures, and primary healthcare (PHC) on breast cancer mortality.

Methods: An ecological study analyzed secondary data of women diagnosed with breast cancer who died between 2000 and 2019. Sociodemographic factors, screening procedures, and PHC were examined in relation to breast cancer mortality. Statistical analyses included normality tests, Kruskal-Wallis and one-way ANOVA tests with post hoc comparisons, Pearson and Spearman correlation tests, age-period-cohort analysis, Kaplan-Meier analysis, and Cox regression analysis. Significance was set at p < 0.05.

Results: Mortality rates were higher in the southeast (15.77) and south (15.97) regions compared to the north (5.07) (p < 0.0001). Survival rates were longer in the southeast (70.3 ± 0.05) and south (70.6 ± 0.09) than in the north (63.98 ± 0.053) (p ≤ 0.001). Mortality increased with age after 32 years (p ≤ 0.001). Brown and indigenous women had lower mortality and survival rates. Increased coverage of PHC, ultrasound, and biopsy did not reduce mortality. However, improved cytopathologic analysis led to a decrease in mortality.

Conclusions: Sociodemographic factors, screening procedures, and PHC are specific predictors of breast cancer mortality in Brazil.

社会形态因素、筛查和卫生服务组织对巴西癌症死亡率的影响：20年生态学研究。

背景：癌症死亡率在巴西呈上升趋势。本研究探讨了社会人口统计学因素、筛查程序和初级保健（PHC）对癌症死亡率的影响。方法：一项生态学研究分析了2000年至2019年间死于癌症的女性的二次数据。研究了社会形态因素、筛查程序和PHC与癌症死亡率的关系。统计分析包括正态性检验、Kruskal-Wallis和带事后比较的单因素方差分析检验、Pearson和Spearman相关性检验、年龄段队列分析、Kaplan-Meier分析和Cox回归分析。显著性设定为p＜0.05。结果：东南部（15.77）和南部（15.97）地区的死亡率高于北部（5.07）（p＜0.0001）。东南部（70.3±0.05）、南部（70.6±0.09）的存活率长于北部（63.98±0.053）（p≤0.001）。32岁后死亡率随年龄增加而增加（p≤001）。棕色人种和土著妇女的死亡率较低死亡率和存活率。PHC、超声和活检覆盖率的增加并不能降低死亡率。然而，细胞病理学分析的改进降低了死亡率。结论：社会形态因素、筛查程序和PHC是巴西乳腺癌症死亡率的具体预测因素。
