Abstract
10032 Background: Burkitt Lymphoma (BL) is a common pediatric cancer in sub-Saharan Africa. Despite advances in care, prognosis is poor. The BL treatment protocol at our center in Kenya used since 2010, had a one-year survival of 29% (Martijn et al. BMJ Paed Open 2017). We hypothesized that financial burdens and delays in start of therapy impact outcomes. Methods: Our trial tested interventions aimed to: 1) Shorten time from presentation to start of treatment to improve survival; and 2) Support families during therapy to reduce abandonment. Initial eligibility included clinical suspicion of BL in a child 0-13 years of age. Patients with confirmed diagnosis of a mature B-cell lymphoma received support to complete therapy. Children with prior treatment of cancer were excluded. The trial was approved by human protection boards in Kenya and Indiana and consent was obtained prior to study entry. We enrolled 96 children with possible BL. Study personnel expedited routing of tissue samples to laboratories. Touch preps or smears were stained with Giemsa and reviewed by pathologists. Fresh tissue from all sources was used for flow cytometry. Tissue from core needle or incisional biopsies was processed for routine and immunohistochemical staining. Of 96 patients, 43 had BL confirmed by pathologic studies and were treated with combination chemotherapy given over 25 weeks. We paid families for transport costs for care, called after missed appointments, and provided direct monetary support (~$200 USD) for the 200 days children were on treatment. Results: Facilitating the biopsy shortened, by 3 days, the median time from admission to initiation of therapy for BL, because families did not need to raise funds for testing. Monetary support reduced abandonment of treatment by patients. Only 2 of 43 (5%) patients abandoned therapy, compared to abandonment by 22 of a cohort of 63 (35%) patients treated previously (p < 0.001). The combination of rapid diagnosis, early therapy, and financial support and communication with families improved event free survival of children with BL to 50% at 1 year (p = 0.045). Conclusions: Simple interventions to improve efficiency of diagnosis and reduce abandonment leads to improved outcomes for children with BL in Kenya.
