Multiple large tumour fragments were submitted for neuropathological evaluation. The BTTB prepares batches of frozen human brain tumours and matching normal tissue and clinical data for neuro-oncology research in Canada and internationally. Standardised tissue and blood collection methods allow excellent preservation of mRNA and enzymes. A second third is embedded in OCT and frozen. The central third is processed for light microscopy to determine the quality of banked tissue.
Stored tissue is linked to basic demographic, clinical follow-up and treatment information.
