In the citation burst analysis, we identified that the earliest highly cited paper with the strongest citation burst was published in 2010: “Integrated genomic analysis identifies clinically relevant subtypes of glioblastoma characterized by abnormalities in PDGFRA, IDH1, EGFR, and NF1.” This study played a pivotal role in glioblastoma classification, revealing distinct molecular subtypes based on genetic alterations in PDGFRA, IDH1, EGFR, and NF1. Here, IDH1 is linked to glioblastoma.
