Abstract 101: The Tanzanian Pediatric Cancer Network: A Comprehensive Evaluation of the Incidence of Presenting Patients and Access to Pediatric Cancer Care in Tanzania

Purpose: In sub-Saharan Africa, cancer treatment facilities are often scarce and centered in urban areas, which means many patients must travel long distances to reach cancer care. Still, little is known about how this distribution of cancer centers impacts patients9 ability to access care. Methods: Records of all pediatric patients ( Results: In 2019, a total of 821 pediatric patients were diagnosed with cancer with an incidence of 1.42/100,000 population. The most common diagnoses were Wilms tumor (17.2%, n=134), retinoblastoma (16.8%, n=131), and acute lymphoblastic leukemia (15.9%, n=124). There was regional variation by diagnosis, with the Lake Zone having the highest incidence of Burkitt lymphoma (0.29; average 0.15) and retinoblastoma (0.5; average 0.33). Reported regional incidence inversely correlated to distance to cancer treatment facility. Median travel time to cancer care for patients was 4.55 hours. Currently 74.5% of the population lives within 4 hours of existing cancer care facilities, and it would require adding cancer care capacity to 8 additional facilities to reach 95% coverage. Conclusions: This is the first comprehensive evaluation of the incidence of presenting pediatric cancer patients in Tanzania. Only 18.8% of the estimated pediatric patients with cancer in Tanzania were treated in 2019. The reported incidence was lower in areas further away from treatment centers, suggesting the importance of increased access to cancer care facilities as part of a future national scale-up strategy.
