Monitoring Disease Progression in GEP-NETs

In gastroenteropancreatic neuroendocrine tumors (GEP-NETs), assessment of tumor size alone is a suboptimal means of tracking disease progression. This is because GEP-NETs tend to grow slowly, and treatments tend to stabilize, rather than shrink the tumor.1-3 Therefore, it is important to monitor progression criteria for GEP-NETs such as morphological progression,1,4 symptomatic progression,1,5,6 and progression on nuclear medicine imaging.1,7 See recommended monitoring frequency and additional details in the infographic below.
