Study of prevalence pattern of neoplastic intracranial tumor in the tribal area of Rajasthan, India

Cheeni Jain, Vivek Kumar Jain, N. Mogra


Background: Prevalence estimates available for brain tumors reflect the portion of tumors that are malignant. Just as routine incidence statistics from cancer registries under represent the full spectrum of primary brain tumor cases. Prevalence rates are ideally suited to provide an overall estimate of cancer survivorship and direction for health planning.

Methods: A total of 70 cases of CNS tumors were retrieved from the archives of the Department of Pathology, Geetanjali Medical College & hospital, Udaipur from April 2014 to September 2016. The diagnoses in all the cases were made on histological examination of processed tissue.

Results: In our study astrocytoma was the most common brain tumor (34.28%), followed by meningioma (32.85%). The third common tumor was oligodendroglioma (11. 42%). However, metastatic brain tumors were seen in only 5.55 % of cases in the present study.

Conclusions: Males were at higher risk of developing CNS lesions in comparison to females. WHO Grade I lesions were more common in our institutional set up. Astrocytoma WHO grade IV lesions were more common in comparison to Grade I lesions, indicating need for imaging and neurology consultation at primary grass root level.
