A Case of Success With Immunotherapy After Changing the Therapeutics Strategy in Non-small Cell Lung Cancer.

Immune checkpoint inhibitors (ICI) have already shown benefit with higher response and survival rates when compared to standard chemotherapy in advanced non-small cell lung cancer (NSCLC). Although there is evidence that radiation and immunotherapy offer good response rates without additional toxicity, these treatments are not currently utilized in our everyday clinical practice to treat advanced disease. We present a case of success of a 50-year-old male with stage IIIC adenocarcinoma of the lung with high PD-L1 expression and no driver mutations whose disease progressed after two cycles of induction chemotherapy.
