Abstract
BACKGROUND
Glioblastoma (GBM) is the most common primary brain tumor. Epidemiologic studies on GBM are rarely reported in the special age group of adolescents and young adults (AYA) in comparison to other age groups. We aim to present data on GBM in Jordan, with a focus on the AYA age, including the incidence, gender, location and outcome, as well as long term survival (LTS).
METHODS
Data on GBM was requested from the Jordan Cancer Registry (JCR), and statistical analysis was performed. All data were retrospective and anonymized.
RESULTS
Eight hundred GBM cases were analyzed from 2000 to 2016 including 505 males (63.1 %). Males outnumbered females across are studied years (p-value <0.001). There were 49 pediatrics (0-14 years, 6.1 %), 125 AYA (15-39 years, 15.6 %), 358 adults (40-59 years, 44.8 %) and 268 elderly (60+ years, 33.5 %) cases. Supratentorial location predominated across all age groups (p-value <0.001). The preponderance of males and supratentorial tumors remained across the AYA age group in comparison to others. The median overall survival (OS) was 23.61 months. AYA age group had a better outcome in comparison to the adults/elderly age group (p-value< 0.001). LTS appear to be more common in the AYA age group (p-value 0.021).
CONCLUSIONS
This is the first comparative epidemiologic study of GBM in Jordan, focusing on the AYA age group. The AYA age group appears to be associated with a better outcome compared to older age groups, with more LTS compared to others.
