The CPS score is the tumor immunity CPS score, and its negative result indicates that the patient’s tumor has poor sensitivity to immunotherapy or the patient is not suitable for treatment with immunosuppressants. The CPS score of tumor immunity generally refers to the comprehensive positive tumor immunity score, which can be used to determine whether the PD-1/PD-L1 monoclonal antibody is effective in treating the tumor, and the larger the value indicates that the tumor is more sensitive to immunotherapy, the immunotherapy efficacy is better and the adverse effects of the treatment are smaller. If the patient’s puncture specimen is found to have a CPS score of 0%, then the patient’s CPS score is considered negative, indicating that the patient’s treatment with immunosuppressive drugs is ineffective, and the tumor may not be under good control. If the CPS score is negative after immunosuppressant treatment, the patient should change the treatment plan under the guidance of the doctor, which can be changed or combined with other drugs. If you are suffering from tumor, please consult the hospital in time, and actively diagnose and treat the tumor as early as possible so as not to delay the condition.
