Survival of women with cervical cancer in East Africa: a systematic review and meta-analysis

Abstract

Background The prognosis for cervical cancer varies greatly between nations. The disparity in cancer survival rates within nations is largely a result of disparities in public knowledge, the accessibility of cancer services, diagnosis and treatment. The purpose of this systematic review and meta-analysis is to assess the survival rate and associated factors among cervical cancer patients in East Africa. Methods Literature search was carried out using Google scholar, PubMed/Medline, Embase and CINHAL. Covidence, a web-based program, was used to import studies for review process. PRISMA guidelines were followed. A total of 110 abstracts were identified from electronic sources. There were five duplicate articles removed. We looked at 105 papers’ abstracts and titles, and we excluded 78 of them because they did not fit our inclusion criteria. We conducted a full-text analysis of the remaining 27 papers, leaving out 14 researches that did not fit our inclusion requirements. For final review, 13 studies were included. Using the Joanna Briggs Institute (JBI) assessment checklist, methodological quality was evaluated. Results The included articles were cohort studies. They were conducted in Ethiopia, Uganda, Zimbabwe, Kenya, Sudan, Tanzania and Rwanda. One-year, two-year, three-year, four-year and five-year overall survival rates ranged from 67% to 92%, 55% to 84%, 44% to 53%, 32% to 47%, and 26% to 43%, respectively. Conclusions The pooled one-year, two-year, three-year, four-year and five-year survival rates of cervical cancer patients in East Africa were 84%, 71%, 50%, 39% and 36%, respectively. HIV status, late presentation, treatment modalities, older age and presence of comorbidities were the most commonly mentioned prognostic factors for survival.
