A low PD-L1 score that is usually discussed in combination with chemotherapy.
Parent marker: PD-L1
Not a diagnosis and not final medical advice. Must be reviewed by a doctor.
Clinical meaning
In this group immunotherapy is generally discussed together with chemotherapy. Other markers such as TMB may add consideration.
How this finding appears in a report
The TPS score is reported along with the antibody and platform used by the laboratory.
When therapy stops working
Changes in scores after therapy may occur so re-examination is sometimes considered.
What needs verification
- Complete variant name as written in the laboratory report.
- Examination methods and types of samples used.
- Examination dates were compared with ongoing therapy.
Marker context: PD-L1
PD-L1 scores are reported to differ according to cancer type: TPS (tumor proportion score) in lung cancer, CPS (combined positive score) in gastric cancer. Rates from one type of cancer cannot be transferred to another type of cancer.
A negative result does not always mean absent
