Dr. Weiss on PD-L1 Biomarker in Lung Cancer

Jared Weiss, MD, assistant professor, UNC Lineberger Comprehensive Cancer Center, discusses the development of biomarkers in the study of lung cancer.

PD-L1 is a much contested biomarker in this field, Weiss explains. While its positive predictive value is beneficial, PD-L1 expression does not provide a stable negative predictor.

According to Weiss, researchers should move on from PD-L1 and start looking into different biomarkers such as mismatch repair, mutational load and mRNA expression signatures, which all show promise.
