Neuro-oncology research has increasingly focused on the molecular and clinical diversity of tumors such as primary central nervous system lymphoma (PCNSL) and glioblastoma. A comprehensive multi-omic analysis of 147 immunocompetent PCNSLs revealed significant heterogeneity, leading to the identification of four prognostically significant clusters (ref: Hernández-Verdin doi.org/10.1016/j.annonc.2022.11.002/). In a randomized phase III trial, the addition of temozolomide (TMZ) to high-dose methotrexate (HD-MTX) and whole-brain radiotherapy (WBRT) was evaluated for newly diagnosed PCNSL, showing improved survival outcomes (ref: Mishima doi.org/10.1093/neuonc/). Furthermore, a phase 3 trial of autologous tumor lysate-loaded dendritic cell vaccination in glioblastoma patients indicated a median overall survival of 19.3 months, significantly higher than the control group, suggesting potential therapeutic benefits (ref: Liau doi.org/10.1001/jamaoncol.2022.5370/). The exploration of glioblastoma-derived extracellular vesicles as diagnostic tools following treatment with 5-aminolevulinic acid also highlights the evolving landscape of liquid biopsy approaches in neuro-oncology (ref: Hsia doi.org/10.1002/jev2.12278/). These studies collectively underscore the importance of personalized treatment strategies based on tumor biology and molecular profiling.
