Abstract
O estudo teve como objetivo estimar a prevalência e a letalidade das neoplasias cerebrais primárias em crianças entre 1-15 anos, Bahia, 1995. O desenho foi de corte transversal, incluindo todos os casos de neoplasia cerebral diagnosticados por múltiplas fontes. A partir dos casos identificados foi utilizado o método de captura-recaptura para estimar o provável número real de casos e medir as prevalências, com intervalos de confiança (IC) a 95%. Por este método estimou-se a existência de 87 casos (IC = 64 ;111) de neoplasias cerebrais no Estado, sendo 72 (IC =54 ; 91) na capital. A prevalência resultante foi 1,85/100 000 crianças entre 1 e 15 anos (IC =1,36; 2,36/100 000) para o Estado e 10,1/100 000 (IC = 7,58 ;12,77/100 000) para a capital. A letalidade foi 5,4% (IC = 4% ; 8%) para a capital e 8,9% (IC =7% ; 13%) para o estado. O método de captura-recaptura mostrou elevada precisão na estimativa do total de casos. Possíveis causas para o não diagnóstico e/ou tratamento das neoplasias cerebrais são comentadas.
The aim of the study was to estimate the prevalence and fatality rate of primary cerebral neoplasms among children between 1 and 15 years old, State of Bahia, Brazil,1995. It was a cross-sectional study which includes all cases of brain tumors diagnosed by several sources. From these cases the capture-recapture method was used to estimate the probable number of cases and measure the prevalence and confidence intervals at 95%. By this method it was estimated the existence of 87 cases (CI = 64 ; 111) of brain tumores in the State, being 72 (CI = 54 ; 91) in the capital. The estimated prevalence was 1.85/100 000 for children between 1 to 15 years old (CI = 1.36 ; 2.36/100 000) for the State, and 10.1/100,000 (CI = 7.58 ; 12.77/100,000) for the capital. The fatality rate was 5.4 percent (CI = 4% ; 8%), and 8.9% (CI = 7% ; 13%) for the capital and the State respectively. The capture-recapture method showed high precision to estimate the total number of cases. Possible causes of no diagnostic nor treatment of cerebral neoplasms are discussed.
