Breast cancer overall survival, annual risks of death, and survival gap apportionment in sub-Saharan Africa (ABC-DO): 7-year follow-up of a prospective cohort study.

ABSTRACT:

Background

There are few estimates of breast cancer survival and its determinants at 5 years and beyond in sub-Saharan Africa. We aimed to estimate survival up to 7 years, estimate annual mortality risk, and apportion survival gaps.

Methods

The African Breast Cancer-Disparities in Outcomes (ABC-DO) prospective cohort study was done at eight hospitals across five sub-Saharan African countries (Namibia, Nigeria, South Africa, Uganda, and Zambia). We prospectively recruited women (aged ≥18 years) who attended hospital with suspected breast cancer. Vital status was updated telephonically once every 3 months for 7 years. We collected detailed sociodemographic, clinical, and treatment data. The primary outcome was overall survival. We estimated age-standardised net survival, condi
