Burkitt's lymphoma treatment in a rural hospital in Sierra Leone

Background: Sierra Leone is a low-income sub-Saharan country in the endemic Burkitt's lymphoma (BL) belt. We performed a prospective trial of a reduced-intensity chemotherapy protocol for the treatment of paediatric BL. Patients and methods: The trial included all children clinically diagnosed with BL between 2005 and 2008. Biopsy, bone-marrow aspiration, analysis of cerebrospinal fluid, abdominal ultrasound and plain x-ray of involved sites were performed when feasible. The treatment protocol was a first i.v. dose of cyclophosphamide (CPM) 40 mg/kg, followed by oral CPM weekly for two doses and then bimonthly to a total of six doses. Treatment was based on clinical diagnosis as it was several weeks before pathology results were available. Results: Eighty-seven patientswere included, with a median age 7 years and 4 months; 59/87 (67.8%) were boys. Nearly half (n 1/4 17, 42.5%), presented with moderate or severe malnutrition. Biopsywas performed in 44 patients, BL being verified in 36 (41.4% of all patients). Most children presented with advanced disease: 28 (32%) at stage II, 47 (54%) at stage III and 12 (13.8%) at stage IV. Most patients (71/87, 82%) initially responded to treatment, but just over half (47/87, 54%) experienced relapse and refractory disease. Forty patients (46%) in complete or partial clinical response were lost to follow-up. Conclusion: The outcome for BL in rural Sierra Leone according to this protocol is poor. Low-dose CPM was in effective. Constraintson performing complete diagnosis and staging, frequency of advanced disease at presentation and a high drop-out rate might explain our poor results. © The Author 2013.
