Cervical cancer survival times in Africa

Abstract

ObjectiveAccessibility to quality healthcare, histopathology of tumor, tumor stage and geographical location influence survival rates. Comprehending the bases of these differences in cervical cancer survival rate, as well as the variables linked to poor prognosis, is critical to improving survival. We aimed to perform the first thorough meta-analysis and systematic review of cervical cancer survival times in Africa based on race, histopathology, geographical location and age.Methods and materialsMajor electronic databases were searched for articles published about cervical cancer survival rate in Africa. The eligible studies involved studies which reported 1-year, 3-year or 5-year overall survival (OS), disease-free survival (DFS) and/or locoregional recurrence (LRR) rate of cervical cancer patients living in Africa. Two reviewers independently chose the studies and evaluated the quality of the selected publications, in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA-P). We used random effects analysis to pooled the survival rate across studies and heterogeneity was explored via sub-group and meta-regression analyses. A leave-one-out sensitivity analysis was undertaken, as well as the reporting bias assessment. Our findings were reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA-P).ResultsA total of 16,122 women with cervical cancer were covered in the 45 articles (59 studies), with research sample sizes ranging from 22 to 1,059 (median = 187.5). The five-year overall survival (OS) rate was 40.9% (95% CI: 35.5–46.5%). The five-year OS rate ranged from 3.9% (95% CI: 1.9–8.0%) in Malawi to as high as 76.1% (95% CI: 66.3–83.7%) in Ghana. The five-year disease-free survival rate was 66.2% (95% CI: 44.2–82.8%) while the five-year locoregional rate survival was 57.0% (95% CI: 41.4–88.7%).ConclusionTo enhance cervical cancer survival, geographical and racial group health promotion measures, as well as prospective genetic investigations, are critically required.
