Core Tip

Core Tip: In this paper, we report a patient with metastatic epidermal growth factor receptor-mutant non-small cell lung cancer showed dramatic response to immunotherapy after pemetrexed plus carboplatin and achieved a durable disease control over 10 mo. We aimed to analyze the potential reasons why the patient can benefit from immunotherapy and explore the strategy that should be adopted in the future.
