From: Molecular diagnostics helps to identify distinct subgroups of spinal astrocytomas
Characteristics of spinal astrocytomas. Diagnoses are based on the integration of histological assessment, molecular genetics and, where available, methylation classifier results. The presence of endothelial proliferation and necrosis was assessed by H&E histology, the Ki67 labelling index by immunohistochemistry. LOH 1p/19q, loss of heterozygosity at 1p/19q
