ZHURNAL VOPROSY NEIROKHIRURGII IMENI N. N. BURDENKO 2022; 86:21-27.

Abstract
OBJECTIVE To study the effect of TERT mutation on overall and relapse-free survival in patients with IDH-negative diffuse astrocytomas grade III (anaplastic gliomas). MATERIAL AND METHODS The study included 45 patients aged 45.5 years. Forty-two patients underwent resection of tumor, other 3 ones - stereotactic biopsy. TERT mutation was identified in 21 patients. External beam radiation therapy was performed in 35 patients (60 Gy), chemotherapy - in 34 patients (mainly temozolomide). Follow-up data were available in 44 patients. RESULTS Median of overall survival in patients with TERT mutation was 15.3 months, in patients with TERT-negative tumors - 65.1 months. Median of relapse-free survival in patients with TERT-positive anaplastic astrocytoma (AA) was 13.3 months, in patients with TERT-negative glioma - 57.7 months. These differences were not significant. Relapse-free survival was higher in patients with AA and no TERT mutation at all intervals, but especially at early stages (12 and 24 months). CONCLUSION Inclusion of TERT mutation in mandatory examination panel for gliomas in general and, in particular, gliomas grade II/III without IDH mutation can lead to sub-classification of these tumors in the near future. Routine analysis of TERT mutation in these patients will be valuable for correct medical consultation regarding prognosis and adequate adjuvant treatment.

Prognostic impact of PDGFRA gain/amplification and MGMT promoter methylation status in patients with IDH wild-type glioblastoma. Neurooncol Adv 2022; 4:vdac097.

Abstract
Background Platelet-derived growth factor receptor alpha (PDGFRA) is the second most frequently mutated tyrosine kinase receptor in glioblastoma (GBM). However, the prognostic impact of PDGFRA amplification on GBM patients remains unclear. Herein, we evaluated this impact by retrospectively analyzing outcomes of patients with IDH wild-type GBM. Methods Using a custom-made oncopanel, we evaluated PDGFRA gain/amplification in 107 GBM samples harboring wild-type IDH, along with MGMT promoter (MGMTp) methylation status. Results We detected PDGFRA gain/amplification in 31 samples (29.0%). PDGFRA gain/amplification predicted poor prognosis (P = .003). Compared to unamplified PDGFRA, PDGFRA gain/amplification in GBM was associated with higher patient age (P = .031), higher Ki-67 score (P = .019), and lower extent of surgical resection (P = .033). Unmethylated MGMTp also predicted poor prognosis (P = .005). As PDGFRA gain/amplification and unmethylated MGMTp were independent factors for poor prognosis in multivariate analyses, we grouped GBM cases based on PDGFRA and MGMTp status: poor (PDGFRA gain/amplification and unmethylated MGMTp), intermediate (PDGFRA gain/amplification or unmethylated MGMTp), and good (PDGFRA intact and methylated MGMTp) prognosis. The Kaplan-Meier survival analysis indicated that these groups significantly correlated with the OS of GBM patients (P < .001). Conclusions Here we report that PDGFRA gain/amplification is a predictor of poor prognosis in IDH wild-type GBM. Combining PDGFRA gain/amplification with MGMTp methylation status improves individual prognosis prediction in patients with IDH wild-type GBM.

Identification of three tumor antigens and immune subtypes for mRNA vaccine development in diffuse glioma. Theranostics 2021; 11:9775-9790. [PMID: 34815785 PMCID: PMC8581422 DOI: 10.7150/thno.61677] [Citation(s) in RCA: 24] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/15/2021] [Accepted: 09/19/2021] [Indexed: 12/31/2022] Open
Abstract
Rationale: Diffuse glioma patients have high mortality and recurrence despite multimodal therapies. This study aims to identify the potential tumor antigens for mRNA vaccines and subtypes suitable for the immunotherapy of patients with diffuse glioma. Methods: Gene expression profiles and corresponding clinical information were obtained from the Chinese Glioma Genome Atlas (CGGA) and the Cancer Genome Atlas (TCGA) databases. Genetic alterations were extracted from cBioPortal. Differential gene analysis, survival analysis, correlation analysis, consensus clustering analysis, and immune cell infiltration analysis were conducted based on the various databases. Finally, the hub genes, the modules related to tumor antigens, and the immune subtypes were identified using WGCNA method. Results: Three over-expressed, amplified, and mutated tumor antigens, including KDR, COL1A2, and SAMD9, were associated with clinical outcomes. The expression of the three genes had a positive correlation with the abundance of antigen-presenting cells (APCs) and APC marker expression. Subsequently, three immune subtypes (Ims1, Ims2, and Ims3) were distinguished in the TCGA cohort, which exhibited distinct molecular, cellular, and clinical characteristics consistent with the CGGA cohort. Diffuse gliomas with subtype Ims1 were more malignant with immunosuppressive phenotypes and more associated with poor prognosis than the other two subtypes. The three antigens and the immune checkpoints were differentially expressed among the three immune subtypes. Finally, functional enrichment analysis of the genes related to tumor antigens and immune subtypes suggested that they are enriched in many immune-associated processes. Conclusions: KDR, COL1A2, and SAMD9 are potential antigens for developing mRNA vaccines against diffuse glioma. The results suggest that immunotherapy targeting these three antigens is more suitable for patients with subtype Ims1. This study provides insights into immunotherapy for diffuse glioma.

Abstract
ABSTRACT The classification, diagnosis, and biological understanding of high-grade gliomas has been transformed by an evolving understanding of glioma biology. High-grade gliomas, in particular, have exemplified the impact of molecular alterations in pathology. The discovery of mutations in a key metabolic enzyme (IDH), histone genes (H3-3A), and large-scale chromosome changes (+7/-10, 1p/19q) are examples of specific alterations that now supplant traditional histologic interpretation. Here, we review established and recently defined types of adult and pediatric high-grade gliomas with discussion of key molecular alterations that have been leveraged for subclassification, grading, or prognosis.
