Abstract

Recently, great advances have been made in the surgical treatment of intramedullary spinal cord tumors (IMSCTs). Many articles have been published; but looking at the literature of the last 5 years, there are only descriptive reviews and no works in which a literature statistical analysis was performed. Here, we analyzed the literature to identify potential prognosticators of good functional outcome in IMSCT patients. To level out the selected studies, we stratified patients’ neurological status as independent (ambulation possible without caregiver assistance) or disabled (cannot ambulate or can only ambulate with caregiver assistance). 18 out of 125 articles were included in the analysis (691 patients). A significant higher percentage of gross total resection (GTR) in ependymomas, hemangioblastomas and cavernomas compared to the astrocytomas (particularly high-grade gliomas) was observed. We found a strong correlation between a good pre-operative neurological function and a good post-operative and at follow-up (FU) neurological status and between GTR and a good post-operative and at FU neurological status. A significant better outcome was found in ependymomas, hemangioblastomas and cavernomas compared to astrocytomas. Our analysis suggests that an early surgery could be reasonable in IMSCTs, because a good pre-operative neurological function is a strong predictor of good neurological outcome. In patients with high-grade gliomas, there is no indication to attempt a GTR due to the infiltrative growth pattern of this tumor that leads to a higher surgical morbidity. Although not innovative, the evidences of our literature statistical analysis strengthen the results from previous surgical series and descriptive reviews.
