ABSTRACT
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 comoadjuvantes à cirurgia. Considerando-se quemuitos 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.
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.

BACKGROUND: Craniopharyngioma tumors and their treatment can lead to significant long-term morbidity due to their proximity to vital structures. The optimal treatment has been debated for many years. We aimed to review the long-term outcomes of children treated for craniopharyngioma in our institution over the past decade and describe trends in treatment and outcomes over the past 3 decades. METHODS: Charts of children with craniopharyngioma treated and followed at The Hospital for Sick Children between 2001 and 2011 were reviewed. Data regarding findings at diagnosis, treatment, and long-term outcomes were analyzed. Comparison was made with previously published data from our institution. RESULTS: Data from 33 patients are included; mean age at treatment, 10.7 ± 4.8 years. In 18 children (55%), the initial surgical approach was tumor cyst decompression with or without adjuvant therapy, compared with only 0-2% in the preceding decades (P < .01). Diabetes insipidus occurred in 55% of children and panhypopituitarism in 58% compared with 88% (P < .01) and 86% (P < .01), respectively, in the previous 10 years. Overall, there was a 36% reduction in the number of children who developed severe obesity compared with the preceding decade. Body mass index at follow-up was associated with body mass index at diagnosis (P = .004) and tumor resection as an initial treatment approach (P = .028). CONCLUSIONS: A shift in surgical treatment approach away from gross total resection has led to improved endocrine outcomes. This may have beneficial implications for quality of life in survivors.
