Dr. Wistuba on Biomarkers for Immunotherapy in Lung Cancer

Ignacio I. Wistuba, MD, chair, Division of Translational Molecular Pathology, Division of Hematology/Pathology, The College of Texas MD Anderson Most cancers Middle, discusses the present panorama of biomarkers for immunotherapy in lung most cancers.PD-L1 expression and tumor mutation burden (TMB) are the 2 distinguished biomarkers, however there’s nonetheless a lot room for enchancment to advance these even additional, says Wistuba.

Evaluating PD-L1 as a biomarker has turn into efficient, however solely after a couple of years of analysis and dialogue. The identical factor is occurring now with TMB, Wistuba says.There are nonetheless ongoing scientific trials to find out a transparent genotyping platform in TMB that can consequence within the correct therapy. For the longer term, Wistuba provides, a deeper understanding of tumor profiling is critical to develop new biomarkers.
