An overview of PD-L1
scoring by tumour type

Use the right scoring method for each tumour type1

Scoring with TPS or CPS depends on the type of tumour. Different types of tumours may express PD-L1 differently, therefore separate scoring systems have been developed to account for these differences. To optimize your report, use the right PD-L1-expression scoring method for each tumour type.

Note the PD-L1 score cut points for KEYTRUDA® for reporting purposes.
