Survival of patients operated on for breast cancer in Ouagadougou/Burkina Faso.

ABSTRACT

BACKGROUND AND OBJECTIVES: Breast cancer is the most common cancer in women. The objective is to study the survival of patients operated on for breast cancer. METHODS: Descriptive and analytical study of the survival of patients operated on for breast cancer between January 1, 2013 and December 31, 2020 in Ouagadougou. Survival was assessed by the Kaplan-Meier method and comparisons by the log-rank test. Prognostic factors were determined using the Cox model. RESULTS: We collected 550 cases. Overall survival at 5 years was 66.2%. Those under 30 years of age had a low 5-year overall survival (53%). The 5-year overall survival was poor in rural patients (63.5%), triple-negative patients (77.2%), HER2+ patients (50.5%) and stage IV patients (29.8%). In multivariate analysis, higher education (p < 0.001) and higher socioeconomic level (p < 0.001) were associated with better prognoses. CONCLUSIONS: The survival of patients operated on for breast cancer remains to be improved. It is influenced by multiple factors especially the socio-economic and educational level of the patients.
