Background: Germ cell tumors (GCTs) represent approximately 3% of primary pediatric brain tumors in the West, whereas in Asia, they constitute between 8% and 15% of pediatric brain tumors. Methods: We retrospectively studied all patients with intracranial GCT managed at our institute from January 1998 to December 2013. The clinical data and radiological data were analyzed. Results: Forty-eight patients with intracranial GCT including 36 males and 16 females formed the cohort. The proportion of GCT in our study was 0.29%. The mean age was 16.5 ± 2.5 years. Germinomas constituted 56.3% and nongerminomatous GCTs constituted 43.7% of all the tumors. The most common location was posterior third ventricle (58.3%) followed by suprasellar (22.9%). Histopathological diagnosis was obtained in almost all patients (96%). Surgical procedures included tumor decompression (71.7%), stereotactic biopsy (13%), and endoscopic third ventriculostomy and biopsy (15%). Patient's age, location of the tumor, and histology did not influence the survival. Women with GCTs had poorer survival when compared to men. Conclusions: The present study documented a lower hospital-based incidence of GCT in Indian cohort. A multidisciplinary approach including surgical strategy based on location, appropriate radiation planning, and chemotherapy is needed for effective treatment and improved outcomes.
