Abstract
Background: Retinoblastoma is by far the most frequent malignant intraocular tumor of childhood. This study was performed to characterize the clinical, diagnostic, treatment and prognostic aspects in patients with retinoblastoma in three reference centers for this pathology in the city of Recife, Pernambuco - Brazil. Methods: A consecutive series of 85 patients with retinoblastoma was reviewed. The authors selected 66 patients (77.6%) that fulfilled the inclusion criteria for these study. Results: Of a total of 66 patients with retinoblastoma, 4.5% had a previous history of the disease in the family. Males were more affected than females at a ratio (male/female) of 1.12. The mean age of appearance of the first symptoms was 23.8 months, with leukocoria and ocular hyperemia being the most frequent. The mean age at time of diagnosis was 31.7 months and for surgical treatment 32.8 months. The right eye was affected in 42.4% of the cases and the left was involved in 37.9% of cases. The tumor was unilateral in 80.3% and bilateral in 19.7% of the cases. There was extraocular involvement in 62.1%, and it was intraocular in 37.9% of the patients. Treatment was surgery combined with chemotherapy in 47.0% of the patients. 27.3% of the patients died and 19.7% abandoned the treatment. Conclusions: The data on the epidemiology of retinoblastoma found in our city resembles that of other developing countries, concerning the epidemioloy of retinoblastoma.
Objetivo: O retinoblastoma é o tumor maligno intraocular mais freqüente da infância. O objetivo deste estudo foi avaliar aspectos clínicos, de diagnóstico, tratamento e prognóstico em pacientes portadores de retinoblastoma atendidos em três centros de referência para esta patologia na cidade do Recife - PE. Métodos: Revisamos 85 prontuários de portadores de retinoblastoma e apresentamos o resultado da análise de 66 destes pacientes, atendidos durante o período de janeiro de 1985 a julho de 1997. Resultados: Apenas 4,5% tinham história pregressa da doença. O sexo masculino foi mais acometido numa razão homem/mulher de 1,12. A média de idade ao surgimento dos primeiros sintomas foi de 23,8 meses, sendo leucocoria e hiperemia ocular os mais freqüentes. A média de idade ao diagnóstico foi de 31,7 meses e a média de idade ao tratamento cirúrgico foi de 32,8 meses. O olho direito, com 42,4% dos casos, foi mais acometido que o esquerdo (37,9%). O tumor era unilateral em 80,3% dos casos e bilateral em 19,7%. Os tumores eram extra-oculares ao diagnóstico em 62,1%, e intra-oculares em 37,9%. O tratamento mais instituído foi a cirurgia associada à quimioterapia, em 47% dos casos. 27,3% dos pacientes tratados foram a óbito e 19,7% abandonaram o tratamento. Conclusões: Os dados encontrados em nosso estado asseme-lham-se àqueles observados em países em desenvolvimento, no que concerne à epidemiologia do retinoblastoma.
