Glioblastoma (GBM) is the most common lethal primary brain cancer in adults. Despite treatment regimens including surgical resection, radiotherapy, and temozolomide (TMZ) chemotherapy, growth of residual tumor leads to therapy resistance and death. At recurrence, a quarter to a third of all gliomas have hypermutated genomes, with mutational burdens orders of magnitude greater than in normal tissue. Here, we quantified the mutational landscape progression in a patient’s primary and recurrent GBM, and we uncovered Cas9-targetable repeat elements. We show that CRISPR-mediated targeting of highly repetitive loci enables rapid elimination of GBM cells, an approach we term “genome shredding.” Importantly, in the patient’s recurrent GBM, we identified unique repeat sequences with TMZ mutational signature and demonstrated that their CRISPR targeting enables cancer-specific cell ablation. “Cancer shredding” leverages the non-coding genome and therapy-induced mutational signatures for targeted GBM cell depletion and provides an innovative paradigm to develop treatments for hypermutated glioma. Tan et al. introduce “cancer shredding,” a proof-of-concept CRISPR approach for treating recurrent glioblastoma. Utilizing personalized sgRNAs targeting repetitive non-coding sequences, including temozolomide chemotherapy-induced mutational signatures, they show rapid glioblastoma cell depletion. This offers a potential avenue to develop cancer-specific treatments for hypermutated gliomas and other hypermutated cancers.
