				        	Lung cancer is the most common cause of cancer-related death worldwide. There are two classes of lung cancer: non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). NSCLC represents approximately 85% of all lung cancer cases. Immune checkpoint inhibitors (ICIPs) are a class of inhibitors of programmed death-1 and programmed death-ligand 1. Preclinical studies have shown that ICIPs have shown good clinical efficacy and durable response in diverse cancers. Among them, atezolizumab (MPDL3280), an anti-PD-L1 monoclonal antibody, is being investigated as a potential therapy against solid tumors and hematologic malignancies in humans. Pseudoprogression is reported as one of the unique phenomena with immune therapeutic agents. Here we report case of a person with advanced NSCLC who developed pseudoprogression after receiving immunotherapy. We hope this case could help clinicians to make appropriate decision when assessing therapeutic effects of immunotherapy.
