Abstract
BackgroundHospital-based cancer registries can provide information on the magnitude and distribution of cancers in a given hospital. Hospital-based brain tumor registry data, focusing on glioma, from a tertiary care rural neurological center is lacking in the scientific literature. This data can be useful in understanding the need for research and funding required for these specific brain tumors.Data of patients operated for glioma, at our institute, was collected between January 2004 and December 2015. Patients’ clinical details and histopathological diagnosis were recorded. Data were analyzed and compared with that of previously published literature, and inferences were drawn on patterns of reporting and epidemiology.ResultsA total of 1450 cases of glioma, with a mean age of 39.3 (± 17.36 SD) years with males (66.6%) comprising more population as compared to females. Majority of patients 70.8% (n = 1027) belong to the economically active age group of country (18–60 years). Majority of cases (41.4%) were glioblastoma with the next common tumor (22.8%) being diffuse astrocytoma (n = 331) followed by pilocytic astrocytoma (6.2%) and oligodendroglioma (4.5%) in that order. While our data followed similar trends with other Indian data the average age of glioma was a decade younger to what is quoted earlier in Indian and international studies.ConclusionThis data for glioma gives a glimpse of the prevalence of this tumor in a primarily rural population and highlights the need for a National Brain Tumor Registry with the need for the development of evidence-based policymaking and enhanced research into this particular ailment.

Majority of the previous series have focused on brain tumors as a whole, but we have focused our interest on histopathologically proven cases of glioma only
Seventy-five percent of patients were below 53 years. 15.3% (n = 222) pediatric patients were below 18 years of age whereas 13.9% (n = 201) patients were above 60 years of age
Summary
Hospital-based cancer registries can provide information on the magnitude and distribution of cancers in a given hospital. Hospital-based brain tumor registry data, focusing on glioma, from a tertiary care rural neurological center is lacking in the scientific literature. This data can be useful in understanding the need for research and funding required for these specific brain tumors. Glioma constitute 38.7% of CNS tumors, with the highgrade (grades III and IV) variants comprising 59.5% and low-grade (grades I and II) varieties approximately 33.1%. The glioblastoma (40%), followed by metastatic tumors (20%) and meningioma (15%) are the most prevalent CNS tumors in the adult [1]. Majority of the previous series have focused on brain tumors as a whole, but we have focused our interest on histopathologically proven cases of glioma only. There is an increase in the incidence of glioma possibly due to better diagnostic armamentarium or increasing carcinogens around us in
