3.1. Characteristics of the Study Population
The records of 164 patients diagnosed with GBM in Guilan Province from
2014 to 2018 were retrospectively analyzed. The study cohort had a mean
age of 54.34 ± 14.16 years, ranging from 3 to 82 years. Among these, 106
patients (64.6%) were 60 years or younger, and 98 (59.8%) were male.
The higher prevalence in men and patients aged 60 years or younger was
statistically significant (p < 0.001) (Table
1). Moreover, the tumor site displayed overlapping characteristics in
112 patients, constituting 68% of the cases. The most prevalent
specific locations were the frontal lobe in 17 cases (10%), the
temporal lobe in 11 cases (7%), and the parietal lobe in 10 cases (6%)
