WCLC 2024 | Dr. Kenneth O’Byrne:Spatial Metabolic Mapping Accelerates Biomarker Development for Predicting ICI Therapy Responses
Immune checkpoint inhibitors (ICIs) have brought new hope to the treatment of non-small cell lung cancer (NSCLC). However, their effectiveness is limited to only a subset of patients. Current biomarkers, such as tumor mutational burden (TMB) and PD-L1, show limited predictive power. According to Dr. Kenneth O’Byrne’s report(Icon Cancer Centre Greenslope) at the 2024 World Conference on Lung Cancer (WCLC), tests revealing high TMB or PD-L1 positivity only have a positive predictive value of around 40%.
