Core Tip

Core Tip: The application of immune checkpoint inhibitor (ICI) in neuroendocrine neoplasm (NEN) is regulated by the latest clinical practice guidelines. However, immunotherapy has achieved some breakthroughs for high-grade or advanced NENs of the digestive system, for which there is currently no effective drug therapy. In this regard, we investigated the causes of the heterogeneous efficacy of ICI in NEN with different grades, differentiation, and primary organs. This review summarizes the state-of-the-art progress and trend of clinical trials for different ICI-containing regimens in NENs of the digestive system, which will aid in the conduct of subsequent clinical trials and research of related mechanisms.
