All participants with high probability of glioblastoma will initially be included, final inclusion will be dependent on the definitive histopathological diagnosis of the tumor.\n\nThe main question is:\n\nCan the researchers identify a proteomic profile in CSF from study participants with glioblastoma in association with a longer progression free survival? Participants will undergo the following procedures, that do not deviate from normal standard diagnostic care.\n\n1. Lumbar puncture to obtain CSF.\n2. Blood draw.\n3. Trans-surgical tissue sample of the brain tumor. Additionally participants will be planned for follow up appointments every 3 months following the first 12 months after the surgical tumor resection.",[51,52,53,54,55],"Glioblastoma","Glioblastoma WHO Grade IV","Glioblastoma (GBM)","Glioblastoma Multiforme of the Brain","Glioblastoma, Adult",[51,57,58,59,60,61],"Cerebrospinal fluid","CSF","GBM","Proteomics","Biomarker","NOT_YET_RECRUITING","2025-02-21",{"date":65,"type":66},"2025-02-25","ACTUAL",{"date":68,"type":46},"2025-03-01",{"date":70,"type":46},"2028-03-30",{"name":5,"class":6}]
