  • Publication number: 20230220446
    Abstract: The field of the invention generally relates to cancer, including methods for diagnosing, prognosing, and treating cancer. In particular, the field of the invention relates to novel signatures of unique sets of point mutations involving a change of a cytosine or a guanidine, and methods, systems, and components thereof based upon the novel signature for identifying tumor samples having increased tumor mutational burden (TMB). Both the signatures and the methods, systems, and components thereof may be utilized for identifying cancer patients, microsatellite stable-cancer patients in particular, who will effectively respond to immune checkpoint blockade therapy.
