Summary
Introduction

The majority of craniopharyngioma (CF) have a cystic component and only 10% are completely solid. In tumors with a large cystic component, stereotactic drainage or instillation of radioctive and/or chemotherapeutic agents have been used. Only several authors have reported the use of bleomycin for the treatment of cystic CF.

Case report

The authors present the case of a nineteen years oíd patient with a recurrent cystic CF who was treated with intratumoral injections of bleomycin. The patient had been operated on three times before because of regrowth of the tumor. This last time he had a severe disturbance of his visual acuity and a huge regrowth of the cystic CF. An intracystic catheter stereotactically placed was connected to an Ommaya reservoir and, after assuring the impermeability of the cyst, bleomycin was administered through the reservoir up to a total dose of 45mg distributed in six doses. No complications were detected during and after the procedure. A MR performed 4 months after treatment showed a clear reduction in the size of the cyst but 10 months later a new regrowth of the cyst was detected by MR with no new signs or symptoms. A total dose of 30mg divided in six doses was administered. No complications occurred. The MR 18 months after the first treatment showed the reduction in size of the tumor. The ophtalmological study showed almost normal visual acuity in both eyes.

Discussion

Although there is not an stablished protocol for the indication and the form of application of intracystic bleomycin, results with this treatment for cystic CF seem good in the literature. However, the risk of local complications after the administration of intratumoural bleomycin in these patients is around 10%, and some fatal toxic reactions have been recently reported.

Conclusión

Intracystic administration of bleomycin is a valid option as adjuvant therapy for CF in patients with recurrences that are not surgical candidates because of the high risk of complications. The role of bleomycin as a primary treatment for CF and treatment protocols remain to be stablished with additional studies.

Resumen

La mayoría de craneofaringiomas (CF) tienen un componente quístico, siendo solamente un 10% completamente sólidos. Para el tratamiento de tumores con gran componente quístico se han usado el drenaje estereotáxico o la instilación de agentes radioactivos y/o quimioterápicos. Pocos autores han publicado sobre el uso de la bleomicina para el tratamiento de CF quísticos.

Presentamos el caso de un paciente de 19 años con un CF quístico recidivado que fue tratado con inyecciones intratumorales de bleomicina. E1 paciente había sido intervenido en tres ocasiones por recrecimientos del tumor. Esta última vez presentaba una disminución severa de la agudeza visual y un recrecimiento gigante del CF quístico. Con ayuda de estereotaxia se le colocó un catéter intraquístico conectado a un reservorio Ommaya y, tras comprobar la estanqueidad del quiste, se le administró bleomicina a través del reservorio a una dosis total de 45mg repartida en seis veces. La RM realizada 4 meses después mostraba la clara disminución en el tamaño del quiste. 14 meses después una RM mostró un nuevo recrecimiento del quiste, sin existir signos ni síntomas asociados al mismo. Se administró bleomicina a través del reservorio Ommaya a una dosis total de 30mg repartida en 6 dosis. No ocurrieron complicaciones y la RM 18 meses después del primer tratamiento mostró la clara disminución del tamaño tumoral. E1 estudio oftalmológico era casi normal en ambos ojos.

Aunque no existe un protocolo establecido de indicaciones y forma de aplicación de este tratamiento, los resultados de los casos reportados en la literatura parecen buenos. Sin embargo, el riesgo de complicaciones locales tras la administración de bleomicina en estos pacientes está alrededor del 10%, y recientemente se han pubicado efectos tóxicos fatales.

Así pues, la administración intraquística de bleomicina es una opción válida como tratamiento adyuvante para pacientes con CF quísticos recurrentes no condidatos a cirugía por el alto riesgo de complicaciones. El papel de la bleomicina como primer tratamiento para CF y los protocolos de administración aún están por determinar con sucesivos estudios.
