Abstract
Introduction

High grade gliomas are the most common primary malignant brain tumours. Treatment with chemoradiation and adjuvant chemotherapy with Temozolomide may prolong survival but some patients develop complications during or soon after therapy due to radiation necrosis, oedema or tumour progression.

Patients

We report the use of Bevacizumab in four patients with newly diagnosed high grade gliomas who developed cerebral oedema due to tumour progression or radiation necrosis that did not respond to corticosteroids, and who were not candidates for surgical debulking.

Outcomes

All four patients had a rapid response to treatment with bevacizumab, tolerating a decrease of the dose of corticosteroids, and were able to continue their standard therapy.

Conclusions

Bevacizumab is effective in controlling some of the neurological complications from oedema, radiation necrosis, or rapid tumour progression during the initial treatment of malignant gliomas.

Resumen
Introducción

Los gliomas de alto grado son los tumores malignos más frecuentes del sistema nervioso central. El tratamiento con quimiorradioterapia y quimioterapia adyuvante con temozolomida puede prolongar la supervivencia, pero algunos pacientes desarrollan complicaciones durante o poco después de acabar el tratamiento debido a radionecrosis, edema o progresión tumoral.

Pacientes y métodos

Presentamos el uso de bevacizumab en 4 pacientes que desarrollaron edema cerebral en relación con radionecrosis o progresión tumoral durante la fase inicial del tratamiento, con respuesta inadecuada a los corticoides y que no eran subsidiarios de tratamiento quirúrgico por la localización de la lesión o la mala situación clínica.

Resultados

Los cuatro pacientes presentaron una rápida respuesta al tratamiento con bevacizumab, lo cual permitió reducir la dosis de corticoides y continuar el tratamiento estándar.

Conclusiones

Bevacizumab es efectivo en el control de algunas complicaciones neurológicas debidas a edema, radionecrosis o rápida progresión de tumores no extirpables durante el tratamiento inicial de los gliomas malignos.
