1、MARCH2026Trends in Oncology Biomarker Testing in the U.S.Advancing Precision OncologyOver the last two decades,advances in cellular and molecular understanding of cancer have significantly accelerated,leading to better characterization of tumor biology.This has paved the way for a transition towards

2、 increasing use of targeted therapeutics in oncology.Predictive biomarkers enable the use of these therapies.However,gaps remain in achieving optimal biomarker testing across tumor types,potentially resulting in eligible patients not receiving timely treatment.Prior IQVIA Institute research publishe

3、d in 2020 identified major barriers that limit biomarker testing for solid tumors in the U.S.The research assessed biomarker testing evolution over time and offered solutions to help reduce the identified testing barriers in oncology.The purpose of this report is to understand how the biomarker test
