#4194 Temozolomide treatment induces an MMR-dependent hypermutator phenotype in well-differentiated pancreatic neuroendocrine tumors

Introduction: Temozolomide (TMZ), an alkylating agent, is an effective treatment used in multiple tumor types including advanced pancreatic neuroendocrine tumors (PanNET). In glioblastomas, TMZ induces a hypermutator and hyperprogressor phenotype in a subset of patients through MMR deficiency. In advanced colon cancer, TMZ priming increases tumor mutational burden (TMB), favouring immunotherapy efficacy.
