Microdissected gliomas/data analysis.

tissue: abbreviation of diagnosis based on histology. n: number of individual tumors analyzed. differentiation: specifies morphology of microdissected tumor components. Σ (n): sum of cases with respective molecular finding in tumors of similar provenience but different tumor grading (i.e. OII/OIII (*),OAII/OAIII (∫)); without distinction of oligodendroglial and astrocytic morphology. Σ%: percentage of a molecular finding summed up for therespective tumor components in tumors of similar provenience but different tumor grading (i.e. OII/OIII (*), OAII/OAIII (∫)). (upper field: frequency in % in the oligodendroglial tumor component; lower field: frequency in % in the astrocytic tumor components.).
