Abstract
BACKGROUND
Recurrence of breast cancer is a critical indicator of disease progression and survival rates. Therefore, this systematic review and meta-analysis aimed to assess the prevalence of recurrence and associated factors of breast cancer in Sub Saharan Africa.
METHODS
We conducted a thorough search of the following international databases between January 1 and February 7, 2024: PubMed, EMBASE, CINAHL, Google Scholar, Science Direct, and the Cochrane Library. A data extraction format was used by two authors to independently extract all required data. STATA Version 14 was used to evaluate the quantitative data and the Cochrane Q test statistics and I2 test were used to evaluate the heterogeneity among the included studies using a random effects meta-analysis model.
RESULTS
The overall prevalence of breast cancer recurrence is 27.44 % (95%CI: 26.41, 28.46). The highest prevalence was found in Uganda (89.927 % (87.0, 92.851)), followed by Tanzania (82.174 % (77.228, 87.120)). Involved deep surgical margin (OR: 3.62, 95 % CI: 2.11, 5.12), positive lymph node status (OR: 6.85, 95 % CI: 1.42, 12.3)), and histological grade III (OR: 7.43, 95 % CI: 3.56, 11.3)) were all significantly associated factors.
CONCLUSION
The pooled prevalence of breast cancer recurrence in this review was significantly high. Histological grade III, positive lymph node statuses, clinical staging III, and involved deep surgical margin were associated factors. Therefore, frequent monitoring, regular screenings, imaging tests, and consultations with oncologists, take extra care to ensure clear and deep surgical margins using advanced imaging techniques are highly recommended.
