Cost of Operating Population-Based Cancer Registries: Results from 4 Sub-Saharan African Countries.

Large differences exist in the coverage and quality of cancer surveillance systems across the world, with limited data currently available from low-resource settings. Information on the resources required to register cancer cases are needed in order for global, national, regional, and local stakeholders to adequately support cancer registry operations. The objective of this study is to estimate the cost of cancer registration and report the cost per cancer incident case, the cost per inhabitant in the area covered by the registry, and cost allocated to specific registry activities. The International Registry Costing Tool (IntRegCosting Tool) of the Centers for Disease Control and Prevention was used to assess the costs and resources used by 4 registries in sub-Saharan Africa (Zimbabwe, Uganda, Kenya, and Seychelles). The cost of registering a cancer case ranged from $9 to $96, with lower costs in low- and middle-income countries than in the high-income country. The cost of cancer registration at the population level is very low, ranging from 1 to 17 cents per person. The detailed cost information provided in this manuscript can help registries in in sub-Saharan Africa understand the cost of their registry operations and identify approaches to improve efficiency to meet program priorities. Furthermore, it provides additional evidence to inform funding and resource allocation decisions to advance cancer registration in the region.

Esophageal cancer male to female incidence ratios in Africa: A systematic review and meta-analysis of geographic, time and age trends.

Esophageal squamous cell carcinoma (ESCC) remains the predominant histological subtype of esophageal cancer (EC) in many transitioning countries, with an enigmatic and geographically distinct etiology, and consistently elevated incidence rates in many Eastern and Southern African countries. To gain epidemiological insights into ESCC patterns across the continent, we conducted a systematic review and meta-analysis of male-to-female (M:F) sex ratios of EC age-standardised (world) incidence rates in Africa according to geography, time and age at diagnosis. Data from 197 populations in 36 countries were included in the analysis, based on data from cancer registries included in IARC's Cancer Incidence in Five Continents, Cancer in Africa and Cancer in Sub-Saharan Africa reports, alongside a systematic search of peer-reviewed literature. A consistent male excess in incidence rates overall (1.7; 95% CI: 1.4, 2.0), and in the high-risk Eastern (1.6; 95% CI: 1.4, 1.8) and Southern (1.8; 95% CI: 1.5, 2.0) African regions was observed. Within the latter two regions, there was a male excess evident in 30-39 year olds that was not observed in low-risk regions. Despite possible referral biases affecting the interpretability of the M:F ratios in place and time, the high degree of heterogeneity in ESCC incidence implies a large fraction of the disease is preventable, and directs research enquiries to elucidate early-age exposures among young men in Africa.
