Introduction: Globally, gliomas account for > 70% of all brain tumors.In Iraq, there is a tendency towards a higher rate of gliomas.The Iraqi Cancer Registry in 2019 stated that central nervous system tumors were among the top three cancers in Iraq and the top ten cancers in Sulaymaniyah.Method: In this hospital-based frequency analysis study, information from 104 glioma patients was reviewed.Data were then subjected to critical analysis, taking into consideration all relevant factors related to demographic data (age, sex, and ethnicity).The histopathological type, tumor grade, and site of disease were collected.Results: Patients with grade I gliomas had a mean age of 24.7119.08years, while those with grade II, grade III, and grade IV tumors had mean ages of 38.517.02,45.6717.03,and 50.74 17.83 years, respectively (p = 0.001).Grade IV gliomas had a higher percentage (45, 47.4%).HGG (64.2%) were more common than LGG (35.8%).GBM was common in 49 patients (80.3%).The left parietotemporal region was the most common site of gliomas (32.2%).The results indicated that older age at diagnosis was significantly associated with higher risk (OR=1.04,p=0.002).Additionally, tumors located in the parietotemporal region were more likely to have HGG (OR=2.3,p=0.03).Conclusion: HGG, particularly glioblastoma, is more prevalent than low-grade gliomas.The mean age at diagnosis increased with the tumor grade, indicating that older patients were more likely to develop high-grade tumors.Tumor location is also an important factor, with high-grade gliomas more frequently observed in the parietotemporal and frontal lobes.Multivariate analysis identified age and parietotemporal location as the independent predictors of HGG.
