Programmed death-ligand 1, commonly abbreviated PD-L1, is protein with an important role in immune system regulation, and thus cancer aggressiveness.
It is also known as CD274.[1]
Prognosis
- Good prognosis - in high-grade ovarian serous carcinoma, associated with tumour-infiltrating lymphocytes.[2]
Drugs
- Atezolizumab.[3]
Application of PD-L1 antibodies
PD-L1 antibodies are being used to treat:[4]
- Malignant melanoma.
- Non-small cell lung cancer.
- Associated with response predicted by tumour-infiltrating lymphocytes and PD-L1 IHC positivity of the tumour cells.[3]
- Renal cell carcinoma.
