| Abstract: | This article expounds the involvement of subunits encoded by DNA polymerase (POLE) and DNA polymerase delta 1 (POLD1) in DNA replication and proofreading, summarizes the effects of POLE/POLD1 mutations on tumor mutation load and intratumoral immune cell infiltration, and reviews the research progress of POLE/POLD1 mutations in immunotherapy of endometrial cancer, colorectal cancer and lung cancer. This article also discusses the challenges faced by POLE/POLD1 mutations as potential molecular markers for the predicting efficacy of immune checkpoint inhibitors. |
