Pancreatic Radiofrequency Under High Echo-endoscopy in the Management of Pancreatic Neuroendocrine Tumors

Summary

Pancreatic radiofrequency ablation (RFA) could therefore be an alternative to the monitoring of pancreatic neuroendocrine tumors (PNETs) and more particularly nonfunctioning PNETs (NF-PNETs), which is costly and anxiety-inducing for patients. To date, only a few small studies have evaluated this treatment and the results are encouraging. It appears necessary to consider a large-scale study to ensure the efficacy and low morbidity of pancreatic RFA applied to PNETs.
