Molecular alterations in recurrent microdissected gliomas.

*Tumor not suitable for microdissection.
**Oligodendroglioma with discernible tumor component of predominantly astrocytic morphology.
Surgery: designates the individual center of tumor operation:
B: Charité Universitätsmedizin, Berlin, Germany.
#: number of all tumors analyzed.
n (P): number of individual tumor pairs.
P/R: identifies primary (P) and recurrent (R) tumor of each tumor pair.
ID: internal tumor ID.
Tissue: abbreviation of diagnosis based on histology.
het.: retained heterozygosity.
LOH: loss of heterozygosity.
wt: wild type TP53/IDH1.
Figure: Figure illustrating respective molecular data.

Bold characters:
n (P): highlight every second tumor pair of individual patients.
P/R: highlight every primary tumor of individual patients.
In all remaining columns bold characters highlight tumor pairs with heterogeneous distinct molecular alterations in their respective astrocytic and oligodendroglial tumor component.

Italic characters:
Highlight tumor pairs with novel molecular alterations during tumor progression.

Bold italic characters:
Highlight tumor pairs in which molecular alterations of the primary tumor are lost during tumor progression.
