Tumor Antigen Markers

Tumor antigen markers are protein molecules that appear or are abnormally highly expressed during tumor occurrence and development, which may exist on the tumor cell surface or be released into body fluids such as blood. They serve as important indicators for tumor screening, auxiliary diagnosis, efficacy evaluation, and recurrence monitoring; some tumor antigens are also immunogenic and can be recognized by the immune system, making them important targets for tumor immunotherapy and vaccine development.
