GBM
and AA are neoplasic entities of the CNS, with high biological and clinical
aggressiveness. Metabolic phenotyping of high grade glioma may provide new
information for better management of this disease. In this communication, we
show high grade glioma molecular profiles and metabolic subgroups based on
HRMAS spectra of 31 high grade glioma biopsies. One of the subgroups, which
includes most AA samples, reflects a less aggressive type of tumour with
lower levels of phosphocholine. Metabolic discrimination between these subgroups
according to the PCA, include the levels of some metabolites which can be
seen by MRS in vivo.
