Abstract:
We analyzed the longitudinal concentrations and prognostic roles of plasma β-synuclein (β-syn), glial fibrillary acidic protein (GFAP), and neurofilament proteins (NfL and NfH) in 33 patients with malignant gliomas, who underwent surgical and adjuvant therapy. GFAP and NfL levels were increased in patients with glioblastoma compared to cases with other tumors. β-syn, NfL and NfH increased after surgery, whereas GFAP decreased at long-term follow-up. β-syn and neurofilament concentrations were influenced by surgery and/or radiotherapy regimens. GFAP and neurofilament levels were significantly associated with survival. Plasma neuronal and astrocytic biomarkers are differentially altered in malignant glioma types and displayed distinct trajectories after surgical and adjuvant therapy.
