Tumor-initiating genetics and therapy drive divergent molecular evolution in IDH-mutant gliomas
Astrocytomas and oligodendrogliomas are slow-growing and treatment-sensitive IDH-mutant gliomas diagnosed at ages 30-50. Local tumor regrowth and treatment resistance is inevitable resulting in 3-10 y...
