Durable Response to Maintenance Treatment Comprised of Viagenpumatucel-L, Nivolumab, Ramucirumab, and Docetaxel in a PD-L1-Low Advanced-Stage Non-Small-Cell Lung Cancer: A Case Report

Case Reports in Oncology, 2023
Checkpoint inhibitors (CIs) are now standard of care for late-stage non-small-cell lung cancer (NSCLC); however, only a minority of patients treated with a CI show clinical benefit compared to platinum-based chemotherapy alone, regardless of programmed ...
