Genomic Alterations in Molecularly Defined Oligodendrogliomas

Neurosurgery 96:328–337, 2025

• Study Focus: Genomic alterations in oligodendrogliomas using standardized NGS panels.

• Key Genes: CIC, FUBP1, and TERTp are the most frequently altered genes.

• Patient Cohort: Retrospective analysis of 95 patients with NGS reports.

• Methodology: Kaplan-Meier plots and log-rank tests for survival analysis.

• Findings: CIC alterations linked to reduced PFS at earlier time points.

• Additional Genes: NOTCH1 and PIK3CA show potential prognostic value.

• Clinical Implications: Potential integration of genomic alterations into clinical practice.

• Future Research: Larger studies needed to validate findings.

• Seizures: Most common presenting symptom in patients.

• Treatment: Majority underwent surgery followed by observation.

• Tumor Grade: Predominantly WHO grade 2 at first surgery.

• Mutation Analysis: 435 cancer-related genes analyzed.

• Statistical Tools: MATLAB R2022b used for analysis.
