Background: Accurate epidemiological data are vital in estimating the burden of disease in a country. Little is known about the incidence of childhood cancer in Ghana. This study describes the incidence patterns of cancer in children below 14 years and 11 months from 2015 to 2019 at the only two main pediatric cancer referral centers in Ghana: Korle Bu Teaching Hospital (KBTH) and Komfo Anokye Teaching Hospital (KATH).
Method: Data on the incidence of cancer in children below 14 years and 11 months were collected retrospectively between 1st January 2015 and 31st December 2019 from patients' medical folders at KBTH and the cancer registry at the pediatric units of KATH. Descriptive statistics were used to describe the data. Incident rates expressed as age-specific rates (ASRs) per 100,000 person-years using population estimates for age groups and sex in each year, were determined by age groups (0-4, 5-9, 10-14 years and 11 months), sex, region of residence and cancer types based on the International Childhood Cancer Classification, third edition.
Results: The total ASR per 100,000 person-years from 2015 to 2019 was 9.36 based on 1073 cases observed. The ASR increased from 1.6 per 100,000 person-years in 2015-2.41 in 2017, thereafter decreasing to 1.45 in 2019. The ASR was higher in male children (2.10 per 100,000 person-years), children between 0 and 4 years (0.27 per 100,000 person-years), and children living in the Greater Accra region (4.17 per 100,000 person-years). The most prevalent cancers were lymphomas (2.17 per 100,000 person-years) and leukemia (1.88 per 100,000 person-years).
Conclusion: The study provides baseline information on the incidence patterns of childhood cancer from 2015 to 2019, addressing a critical gap in childhood cancer epidemiology in Ghana.
