    Abstract:
    Glioblastoma multiforme is a malignant tumour with a universally fatal diagnosis. We report two patients with glioblastoma with symptomatic metastasis to the spinal cord and perform a systematic review all 35 reports of symptomatic glioblastoma dissemination to the spinal leptomeninges and/or intramedullary spinal axis. Our analysis of the data shows a median time to spinal metastasis of 10 months and a median time of three months from spinal metastasis to death. Treatments described include palliative laminectomies, radiotherapy and chemotherapy. No treatment strategy offered a therapeutic advantage as patients deteriorated rapidly regardless of intervention. Patients who underwent only a biopsy for intracranial glioblastoma had a shorter time to development of spinal metastasis. In addition, there may be an association between intramedullary metastasis and shorter survival. This paper highlights the importance of considering symptomatic spinal dissemination in glioblastoma multiforme. We also review the incidence and postulate mechanisms of tumour dissemination in the central nervous system. Clearly, further research into radiotherapeutic and chemotherapeutic options in this clinical setting is required.
