Breast cancer is leading the cancer incidence and mortality ranks worldwide. Currently, breast cancer represents 30.1% of all cancers occurring in women in Congo. In sub-Saharan Africa, breast cancer is diagnosed delayed in 70% of cases. The purpose of this work is to study the epidemiological aspects of patients with late diagnosis of breast cancer at the Brazzaville University Hospital, Congo.
We carried out a cross-sectional analytic study in the medical oncology service of the University Hospital of Brazzaville. We used systematic, exhaustive sampling. Logistic regression was used for data analysis, and values ≤5% were considered significant.
Data for 182 patients were collected. Delay in diagnosis represented 91.21% of cases. Delay in diagnosis was significantly associated with lack of finance ( = 0.011) and with breast cancer stages greater than 2 ( < 0.001), but the proximity to the center was suggestive. Multivariate analysis revealed an association between diagnostic delay and proximity to the center ( = 0.025) as well as with breast cancer stages greater than 2 ( < 0.001).
The delay in breast cancer diagnosis widely discussed in the literature remains relevant in Congo. Routine screening, the construction of a cancer center and its optimal equipment, and the subsidy of care are all critical factors for battling delayed breast cancer diagnosis in Congo.
乳腺癌在全球癌症发病率和死亡率排名中位居前列。目前，乳腺癌占刚果女性所有癌症病例的30.1%。在撒哈拉以南非洲，70%的乳腺癌病例诊断延迟。本研究旨在探讨刚果布拉柴维尔大学医院乳腺癌晚期诊断患者的流行病学特征。
我们在布拉柴维尔大学医院肿瘤内科开展了一项横断面分析研究。采用系统、全面的抽样方法。数据分析采用逻辑回归，P值≤5%被认为具有统计学意义。
共收集了182例患者的数据。诊断延迟占病例的91.21%。诊断延迟与资金短缺（P = 0.011）以及乳腺癌分期大于2期（P < 0.001）显著相关，但距离中心较近有一定提示作用。多因素分析显示，诊断延迟与距离中心较近（P = 0.025）以及乳腺癌分期大于2期（P < 0.001）有关。
文献中广泛讨论的乳腺癌诊断延迟在刚果仍然存在。常规筛查、癌症中心的建设及其优化设备，以及医疗补贴都是刚果对抗乳腺癌诊断延迟的关键因素。
