Incidence of Endemic Burkitt Lymphoma in Three Regions of Mozambique.

Abstract

Data on the burden and incidence of endemic Burkitt lymphoma (eBL) across Mozambique are scarce. We retrospectively retrieved information on eBL cases from reports of the three main hospitals of Mozambique: Maputo Central Hospital (MCH), Beira Central Hospital (BCH), and Nampula Central Hospital (NCH) between 2004 and 2014. For 2015, we prospectively collected information of new eBL cases attending these hospitals. A total of 512 eBL cases were reported between 2004 and 2015: 153 eBL cases were reported in MCH, 195 in BCH, and 164 in NCH. Mean age of cases was 6.9 years (standard deviation = 2.8); 63% (319/504) of cases were males. For 2015, the estimated incidence rate of eBL was 2.0, 1.7, and 3.9 per 106 person-year at risk in MCH, BCH, and NCH, respectively. Incidence was higher in NCH (northern Mozambique), where intensity of malaria transmission is higher. Data presented show that eBL is a common pediatric malignancy in Mozambique, as observed in neighboring countries.
