Multicenter Safety Trial Assessing an Innovative Tumor Molecular and Cellular Print Medical Device in Glioma

Current limitations in the management of high grade brain tumors partly reside in the lack of access to pathological tissue.

Conventional biopsy devices can cause severe side effects, thus limiting the amount of tissue that can be collected for molecular characterization. The Brain-Tissue-Imprint Devices evaluated in this trial offers a unique opportunity to perform multiple non-lesion sampling in both tumor tissue and peritumoral areas. The approach relies on the use of tailored silicon chips integrated in surgical devices enabling tissue sampling through a brief "silicon to tissue contact", thus limiting potential side effects, and opening a way to extensive molecular investigation of brain tumors and their microenvironment.
