This research aims to define functional mutations in DNA polymerases to predict patient response to immune checkpoint blockade in cancer.
Selected solid tumors with DNA panel sequencing from patients at MSK and DFCI to identify somatic POL variants.
Utilized mutational signature deconvolution and AI modeling to assess the impact of polymerase proofreading on tumor development.
Evaluated overall survival and progression-free survival using multivariable Cox regression, incorporating mismatch repair deficiency status.
84% of identified DNA polymerase variants were pathogenic, impacting survival based on polymerase signature intensity.
Patients with high polymerase signatures had significantly better overall survival compared to those with intermediate or null signatures (HR 0.35, 95%CI 0.16-0.80; p=0.01).
Tumors with predicted inactivating variants exhibited survival rates similar to those with pathogenic variants when assessed with mutational signatures.
