The findings of this study demonstrate that the atezolizumab plus carboplatin and nab-paclitaxel regimen as front-line management might provide greater survival benefits in PD-L1-positive metastatic nonsquamous NSCLC patients in a selected population than the carboplatin and nab-paclitaxel regimen, with a tolerable safety profile. The gene discussed is CD274; the disease is non-small cell lung carcinoma.
