Contribution of comparative genomic hybridization (CGH) to the classification of diffuse gliomas

Diffuse gliomas are the most common primary malignant tumors of CNS in adults. These tumors are classified based on to the recommendations WHO 2016 and cIMPACT-NOW. This classification results in an “integrated histo-molecular diagnosis” with better clinical correlation. In fact, it takes into account the results of genetic analyzes. The objective of our work is to discuss the contribution and limitations of CGH to classify diffuse gliomas and describe a cohort of patients with this tumor.
