NSCLC

Biomarkers

The diagnosis of NSCLC typically involves a combination of radiological and pathological assessment.1​​ After a NSCLC diagnosis, comprehensive biomarker testing is crucial in identifying an appropriate patient care plan for the unique characteristics of a patient and their disease.2,3

To obtain samples for diagnostic testing, pulmonologists use several biopsy methods, including EBUS- and CT-guided procedures. Following diagnosis, these samples undergo testing to identify actionable biomarkers that can guide the use of targeted therapies.3-5​​​
