Abstract Text | This cohort study analyzes the medical records of 47 721 patients with various cancer types with POLE/POLD1 mutations to evaluate whether the mutations were associated with immunotherapy outcomes. |

POLD1 | NCBI | CDC2|CRCS10|IMD120|MDPL|POLD | POLD1, DNA polymerase delta 1, catalytic subunit, is the catalytic subunit and the largest of four subunits that form the DNA polymerase delta holoenzyme, which mediates DNA replication (PMID: 27320729) and repair (PMID: 30625304). Germline and somatic mutations in POLD1 have been identified in a variety of human cancers (PMID: 27320729), including colorectal cancer (PMID: 31769227) and lung cancer (PMID: 31673068), and may be associated with high tumor mutational burden and response to immunotherapy (PMID: 31741177, PMID: 31673068, PMID: 31415061, PMID: 30524909). | Tumor suppressor |

POLE mutant | Advanced Solid Tumor | predicted - sensitive | unspecified PD-1 antibody | Clinical Study - Cohort | Actionable | In a clinical study, immune checkpoint inhibitor (ICI) treatment, including CTLA4, PD-1, and PD-L1-targeting antibodies, resulted in prolonged overall survival (34 vs 18 months, p=0.004) in patients with advanced solid tumors harboring POLE or POLD1 mutations compared to wild-type patients, and POLE/POLD1 mutation served as a predictor of response to ICI (p=0.047, HR=1.41) independent of MSI-H status (PMID: 31415061). | 31415061 |
