Treatment sequencing in gastroenteropancreatic neuroendocrine tumors

The oncological treatment of neuroendocrine tumors (NET) has improved significantly in the last few years. Several informative clinical studies on NET have been conducted recently and updated NET guidelines have been published by the European Neuroendocrine Tumor Society (ENETS) in 2023 and 2024. With the growing number of positive phase III trials in NET, the main difficulty today is selecting the most appropriate treatment for a patient at the right time. The purpose of this short review is to delineate the main concepts and important changes in the therapy sequences for gastroenteropancreatic NET (gepNET) outlined in current European guidelines. In clinical practice, more individualized treatment decisions are often required that go beyond these general recommendations.
