Oligodendrogliomas account for a small subset of all gliomas, but they often are more sensitive to treatment than other glioma subtypes. In addition, oligodendrogliomas are the first central nervous system neoplasm for which a specific molecular abnormality, allelic loss of 1p/19q (1p/19q loss), correlates with patient outcome in large-scale prospective clinical trials. However, the incorporation of 1p/19q status into clinical practice remains controversial. Other molecular alterations found in oligodendrogliomas include hypermethylation of the promoter for the MGMT gene, TP53 mutations, EGFR and platelet-derived growth factor/PDGFR alterations, and 9p and 10q loss.

Summary: This study aimed to evaluate the real-world effectiveness of immune checkpoint inhibitors in the treatment of patients with progressive multifocal leukoencephalopathy (PML). Retrospective data from 79 PML patients who received immune checkpoint inhibitors were analyzed, and the results showed that mortality remained high and the development of inflammatory features or PML-IRIS was commonly observed. The study highlights the importance of personalized use of immune checkpoint inhibitors for PML patients.

Summary: This retrospective analysis examined the outcomes and prognostic factors of 539 newly-diagnosed PCNSL patients aged 60 years and older from 20 U.S. academic centers. The study found that induction regimens using high-dose methotrexate (HD-MTX) combined with rituximab, as well as maintenance therapy, optimized the outcomes for older PCNSL patients. Additionally, several factors including age, hypoalbuminemia, high CIRS-G score, and ECOG performance status were associated with inferior outcomes.

Summary: The objective of this multicenter retrospective study was to examine the incidence, patient characteristics, pathology, and outcomes associated with Epstein-Barr virus (EBV)-related CNS lymphoma (CNSL) in older patients. The study found that 11.7% of CNSL patients aged ≥ 60 had EBV + tumors, mainly solid organ transplant-related post-transplant lymphoproliferative disorders (PTLD). EBV positive tumors were associated with younger age, solid organ transplant or autoimmune disease, and immunosuppressive treatment. Furthermore, EBV + PTLD had a shorter median overall survival compared to EBV + non-PTLD and EBV-negative patients.

Summary: The study investigates the use of immunotherapy in treating HGG, with a focus on how radiation can enhance immunogenicity and the feasibility of combination therapy. While some studies have not shown consistent improvements in clinical outcomes, there are still important lessons to be learned from completed research in this early-stage field.
