Prognostic value of ventricular wall fluorescence during 5-aminolevulinic-guided surgery for glioblastoma.
The meaning of the ventricular wall fluorescence during 5-aminolevulinic (5-ALA)-guided surgery in patients with glioblastoma (GBM) is still unknown. The authors studied the association between ventricle fluorescence, clinical outcome and survival, and described the histopathological findings of selective biopsies from the ventricular wall. ⋯ Preoperative MRI predicts if the ventricle will be opened using the 5-ALA fluorescence, according to tumour location. It does not predict, however if the ventricle wall is going to be fluorescent or not. The fluorescence of the ventricle wall is not a predictor for complications or survival. Periventricular tumour location is an independent bad prognostic factor in GBM.
