Clinicopathological pattern of brain tumors: A 3-year study in a tertiary care hospital in India

Background: Brain tumors are heterogeneous group of neoplasms, affecting different age groups. Although some studies have been published regarding pathological pattern of brain tumors from different countries of the world and also from India, comprehensive clinicopathological studies from Eastern India is lacking. Aims: The aim of this study was to observe recent incidence of different brain tumors and to study clinical and histopathological spectrum of brain tumors in Eastern India. Materials and Methods: The present study was a cross-sectional observational study involving 130 cases of brain tumors which were diagnosed during the 3-year study period (January 2010–December 2012). Data regarding clinical presentation and radiological features of all cases were collected from all patients. Histopathological diagnosis was correlated with clinical and radiological diagnosis. Results: We found 130 cases of brain tumor with a male preponderance. The cases were distributed in a wide age range from 4 years to 78 years with the mean age of 42.38 years. Most common tumor type in our study was neuroepithelial tumor (92 cases, 70.76%). Among the neuroepithelial tumors, most frequent subtype was astrocytic tumor (54 cases, 41.5%). The second most frequent brain tumor was meningioma (20 cases, 15.3%). We found higher incidence of oligodendroglial tumor (8.46%) and medulloblastoma (7.69%) in our series. Conclusion: Males are more predispose to brain tumors in comparison to females. Astrocytic tumors are most common subtype in Eastern India. However, the WHO Grade I neoplasms are more frequent brain tumors.
