Resumo
Craniofaringiomas são tumores histologicamante benignos, extrínsecos ao parênquima cerebral. Visando ao controle da doença, preconiza-se, como tratamento padrão, a tentativa de ressecção completa, meticulosamente planejada com vistas a preservar as funções habituais do paciente. Outras formas de terapias podem ser utilizadas como alternativas ou como adjuvantes à cirurgia. Considerando-se que muitos craniofaringiomas apresentam componente cístico, a utilização de cateteres posicionados no interior do lúmen cístico para aplicação de agentes quimioterapêuticos, como o interferon alfa (IFNa), tem-se mostrado promissora. Administração intratumoral de 3 milhões de unidades de IFNa em dias alternados, totalizando doze ciclos, tem sido utilizada empiricamente. Relatamos o caso de uma paciente de 12 anos de idade, com diagnóstico de craniofaringioma de predomínio cístico, tratada no Hospital de Câncer de Barretos (HCB) utilizando a aplicação de IFNa semanalmente, que apresentou evolução favorável.
Abstract
Craniopharyngiomas are histologicaly benign tumors, whose ideal brain treatment requires its complete surgical resection, while preserving most of the usual functions of the patient. Due to the complexity of the surgical procedure, related to location (surrounded by paraselar structures), it is often difficult to achieve its complete resection. Thus, alternative therapies have been reported, including the use of intracystic IFNa on alternate days. We report the case of a 12 year-old female, diagnosed with cystic craniopharyngioma, weekly treated with intracystic IFNa, for a total of 12 cycles, with favorable outcome.
