Breast Cancer Survival at Brazzaville University Hospital from 2011 to 2020

---

Résumé

Introduction: Survival rates for patients with breast cancer have increased dramatically due to increasing exploration of the
role and impact of prognostic factors. Five-year breast cancer survival rates vary considerably around the world, ranging
from over 80% in high-income countries to less than 40% in low-income countries. The aim of our work was to determine
the survival of patients with breast cancer, and the factors associated with this survival in the oncology department of the
Brazzaville University Hospital.
Patients and Method: This was a monocentric, retrospective descriptive study conducted over a ten-year period, from January 1, 2011 to December 31, 2020. Survival curves were calculated using the Kaplan-Meier model, and factors associated
with survival were studied using the Cox model. The significance level was set at 5%.
Results: 354 patients were included, 348 women and 6 men. The mean age at diagnosis was 47.25 years. 74.29% of patients
had T4 stage at diagnosis; 78.53% had lymph node involvement, and 25.14% had metastatic disease. The 5-year overall survival rate was 19%. Survival was significantly associated with age (p = 0.04), general condition (p = 0.03), stage (p = 0.003), specific treatment (p = 0.000), immunohistochemistry (p = 0.000) and time to consultation (p = 0.01).
Conclusion: The incidence of breast cancer is rising worldwide. It is therefore essential to develop a screening strategy that
will enable more effective management and better results.
