SURG-85. Treatment outcomes of pineal region lesions: 23-year experience from a tertiary care center
Year: 2025
Type: conference-abstract
Abstract: INTRODUCTION Tumors in the pineal region are exceptionally rare and comprise only 0.5-1.1% of all brain tumors. The pineal region was once thought of as the ‘forbidden zone’ for surgery due to the significant surgical challenges that it posed, especially due to its deep-seated location. In this study, we aim to describe the experience from a single tertiary care center of managing pineal region lesions. We analyzed the treatment outcomes of the patients. METHODS This is a single-center cross-sectional study. Data for all patients who underwent treatment of pineal region lesions from 2000 to 2023 were included. Relevant data points were extracted from the hospital’s medical records. Descriptive analysis of the data was performed. RESULTS We enrolled 67 patients with a mean age of 22.9±13.52 years. Of them, 54% were male. Most common presenting complaints included headache (92.5%), nausea/vomiting (83.6%), and diplopia (15%). Pre-operative hydrocephalus was reported in 45 (67%) patients. Mean tumor size (largest dimension) was 3.5±1.7 cm. The most common histopathological diagnoses were glioma, germinoma, and pineal parenchymal tumor of intermediate differentiation. Patients who underwent surgical resection, 17 (61%) had gross or near-total resection. Most of the patients had two surgical procedures done, biopsy and tumor resection. An average clinical follow-up of 44.2±56.4 months was calculated. CONCLUSION With technological advances, the surgical management of pineal tumors is improving. We reported an average follow-up of 44.2±56.4 months. Of patients who underwent surgical resection, 61% had gross or near-total resection. Both supra and infra-tentorial approaches were used depending on the tumor location.
