PD-L1-targeted PET imaging for non-invasive assessment of immunotherapy response in lung cancer

Background <p>Immune checkpoint inhibitors have improved outcomes for several malignancies; however, there remains a lack of accurate, non-invasive methods to assess tumor PD-L1 expression levels and guide immunotherapy. This study aimed to evaluate the role of PD-L1-targeted positron emission tomography (PET) imaging in predicting immunotherapy response and prognosis in lung cancer.</p> Methods <p>Four healthy volunteers and 22 treatment-nai&#x0308;ve lung cancer…
