Primary intracranial tumours- A five year hospital based cross-sectional study

Primary brain tumors are a major cause of cancer-related deaths worldwide, and numerous studies have indicated an increase in their incidence over the past two decades. This study aimed to estimate the frequency of primary intracranial tumors presenting at KLE’s DR Prabhakar Kore’s Hospital and MRC, Belgaum, and to examine correlations between various factors, including age, sex, clinical symptoms, and signs. Between January 2006 and December 2010, 159 patients with proven cases of primary intracranial tumour based on CT/MRI scans were included in the study. Gliomas were the most frequent tumor type (45.28%), followed by meningiomas (23.89%). Males were more commonly affected (55.97%) than females, and the most commonly affected age group was 41-60 years, including 74 of the 159 cases (46.65%). Over half of the tumors were located in the cerebral lobes, with the frontal lobe being the most frequently involved. Headaches, seizures, and focal neurologic deficits related to the anatomic site of involvement were the most common presenting signs and symptoms. The findings of this study can be extrapolated to the population of North Karnataka and are consistent with similar studies conducted elsewhere in the country. Additionally, the study reveals a significant relationship between patient age and sex and the occurrence of different tumor types.
