About this study
Official title: Multi-center Prospective Study on EUS-guided Radiofrequency Ablation for Solid Pancreatic Neoplasms
Radiofrequency ablation has been used for treatment of solid neoplasms of the liver, lung, kidney and adrenal. Recently, EUS-guided RFA has become available and the device allows EUS-guided treatment of pancreatic neoplasms. The procedure has been shown to be feasible in the porcine pancreas and was used to treat small groups of patients that are not suitable for surgery suffering from pancreatic neoplasms.
The aim of the current study is to perform a multi-center prospective study on EUS-guided radiofrequency ablation (RFA) of solid pancreatic neoplasms. The hypothesis is that EUS-guided RFA is safe, feasible and effective for treating solid pancreatic neoplasms.
Read the detailed description
RFA causes tissue destruction through the application of a high frequency alternating current, generating local temperatures above 60°C and leading to coagulative necrosis. The technique has been widely used in many solid organ tumors and has been shown to result in 5-year survival rates comparable to surgery. The technique is currently the standard therapy in hepatocellular carcinoma and colorectal pulmonary metastasis particular in patients that are not suitable for surgery.
This study is a multi-center prospective study involving four high volume international institutions. Consecutive patients suffering from pancreatic neuroendocrine tumors and pancreatic cancers would be recruited. EUS-guided RFA would be performed using a 19-gauge RFA electrode and a generator. The primary outcome would be the overall adverse events rate. Secondary outcomes include mortality, technical success rate, completion ablation rate, 1 \& 3 year overall and disease-free survival.
