Pediatric low-grade gliomas; a 12-year retrospective review from a tertiary care hospital in LMIC
摘要
Central Nervous System (CNS) tumors are the leading solid malignancies in children, 50% of CNS tumors in children are glial tumors, with two-thirds of these gliomas being categorized as low-grade gliomas (LGG). We aimed to review the clinical profile, management, and outcomes of pediatric LGG cases.
MethodologyA retrospective cohort study was conducted at Aga Khan University Hospital between 2013 and 2025 including patients aged ≤ 18 years diagnosed with LGG.
ResultsA total of 191 patients were identified, with a slight preponderance of male patients (51.3%). Median age was 10 years (IQR 6–14) with the larger age group being 10–18 years (50.3%). Median duration of presenting symptoms was 4 months (IQR 1–18). Headaches (n = 112, 58.6%) and vomiting (n = 93, 48.7%) were the primary presenting complaints. Tumors were predominantly supratentorial (n = 115, 60.2%). The most common histopathology was Pilocytic Astrocytoma (n = 119). Upfront surgery was done in 163 (85.3%) patients; Gross Total Resection (GTR) was achieved in 85 patients (52.1%). Twenty-six (13.7%) patients received Chemotherapy while 9 (4.8%) had radiation therapy. Disease didn’t progress in 131 (68.6%) patients while progression and relapse occurred in 36 (18.8%) and 7 (3.7%) patients, respectively. Seventeen (8.9%) patients did not have any follow-op scans. The Overall Survival (OS) was 95.3%, with only 9 deaths recorded. Biopsy was deferred to 28 patients (14.7%), a group primarily comprising Subependymal Giant Cell Astrocytomas (SEGA) (n = 17, 60.7%), Tectal Plate Glioma (n = 3, 10.7%), and Optic Path Glioma (n = 5, 17.8%). Kaplan-Meier analysis estimated a median EFS of 84.2 months (95% CI: 70.9–97.5 months). However, this estimate should be interpreted cautiously given the relatively short median follow-up and substantial right-censoring.
ConclusionDespite heterogeneity in histopathology and location, outcomes were comparable to those reported in the literature, underscoring the effectiveness of current practices while highlighting the need for improved follow-up and comprehensive outcome reporting in resource-limited settings.
