OBJECTIVE: To estimate the incidence of central nervous system (CNS) tumors in Suriname. METHODS: A retrospective chart review was performed at the Academic Hospital Paramaribo and the State Health Insurance foundation. Patients receiving a diagnosis of CNS tumor in the period 2000-2010 were included in the study if a computed tomography scan or magnetic resonance imaging study was available. Demographic data and patient characteristics and disease variables were retrieved. RESULTS: The study comprised 251 patients who met the inclusion criteria. The incidence of treated CNS tumors was 5 per 100,000 per year. There was a peak incidence in the 41-50 age group and a male-to-female ratio of 1:1.46. Of CNS tumors, 21% were gliomas, 26.7% were meningiomas, 4.7% were schwannomas, and 12.0% were pituitary adenomas. Suriname has a low glioma incidence compared with globally (40%-60% of CNS tumors globally). The incidence of pituitary adenoma was higher than expected. There are indications for a higher glioma and meningioma incidence in Javanese and a higher metastases incidence in Creoles. CONCLUSIONS: The annual incidence of treated CNS tumors of 5 per 100,000 inhabitants in Suriname was in accordance with the expectation of an incidence of 3-6 per 100,000. Suriname is considered a country with a low cancer incidence. The differences found among various subgroups were too small to make definitive statements.
