Abstract: Neuroendocrine neoplasms (NENs) are a group of malignancies arising from neuroendocrine cells and peptidergic neurons. The high heterogeneity of NENs leads to challenges and complexities in its diagnosis and treatment. Experts from relevant disciplines were convened by the Society of Neuroendocrine neoplasm of China Anti-Cancer Association to develop this first edition of the Chinese Guideline for diagnosis and treatment of NENs (2022) based on existing evidence combined with domestic and international guidelines and consensus. In this article, we summarize the important contents of this guideline and make further discussion on some controversial issues, with the aim to provide treatment reference in clinical practice.
