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.

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.
