Abstract
Background
IDH-wild-type glioblastoma (GBM) is a disease with devastating prognosis. First-line therapy consists of gross total resection and adjuvant radiotherapy with concomitant temozolomide. Several clinical parameters have been identified to provide prognostic value. We investigated whether peri-operative overall neurological performance could also be used to evaluate patients’ prognosis.
Methods
All patients with histologically diagnosed GBM between 2014 and 2017 over 18 years and MRI within 72 h after surgery were reviewed. To quantify neurological performance, the medical research council neurological performance score (MRC-NPS) was used. Univariate analysis with Kaplan–Meier estimate and log-rank test was performed. Survival prediction and multivariate analysis were performed employing Cox proportional hazard regression.
Results
One hundred thirty-nine patients were included. In univariate analysis, survival decreased with increasing post-operative MRC-NPS scale. Moreover, post-operative MRC-NPS of 4 was statistically significant associated with reduced overall survival when analyzed for complete (p = 0.027) and partial resection (p = 0.002) as well as unilobar (p = 0.003) and multilobar tumor location (p < 0.0005). In multivariate analysis, extent of resection (hazard ratio (HR) 3.142), adjuvant therapy regimen (HR 3.001), tumor location (HR 2.005), and post-operative MRC-NPS (HR 2.310) had significant influence on overall survival.
Conclusion
We propose the post-operative neurological performance as an independent prognostic factor for GBM patients.
