CPS medical testing refers to the tumor immuno-scoring method of evaluating the intensity of PD-L1 staining prior to the use of drugs.
Tumor immune CPS scoring method is a way of evaluating the intensity of PD-L1 staining, where the CPS value is the ratio of the total number of macrophages, tumor cells, and lymphocytes that are positive for PD-L1 staining to the total number of tumor cells in the test sample.The CPS score can be used as an indicator of the therapeutic effect of a cancer patient after immunotherapy.
After the CPS test, if the score is relatively high, it means that the treatment with immunotherapy drugs is more effective. If the CPS score is too low, it means that the patient is less effective with immunotherapy.
The evaluation of the efficacy of the treatment and the medication should be done under the supervision of a physician.
