Endoscopic Ultrasound-Guided Radiofrequency Ablation of Pancreatic Cysts - A Safety and Efficacy Trial (ERASE Study)
This clinical trial evaluates the safety and effectiveness of endoscopic ultrasound-guided radiofrequency ablation (EUS-RFA) for the management of patients with pancreatic tumors (including cysts) performed during recommended surveillance endoscopic ultrasound examinations. Pancreatic tumors (cysts) can progress to pancreatic cancer at rate of more than 25% per year risk. Pancreatic cancer is a fatal disease that is difficult to diagnose at an early stage, and the five-year survival rate is currently less than 10%. It is projected to be the second leading cause of cancer-related mortality by the year 2030. A procedure known as radiofrequency ablation may help. Radiofrequency ablation is an established way to treat benign and cancerous tumors in the human body. In the last 5 years, radiofrequency ablation has been applied to treat precancerous tumors (including cysts) in the pancreas. This procedure implements a medical technology that destroys tumors in a much less invasive way compared to traditional surgical removal. By delivering a high-frequency alternating current, radiofrequency ablation uses electrical energy and heat to destroy cancer cells. Radiofrequency ablation is being recognized as a management option in patients with high-risk pancreatic tumors (cysts) but are not deemed surgical candidates. While surgical removal offers a chance of cure, pancreatic surgeries have 20-40% morbidity rate (short and long-term complication) and a 1-2% mortality rate in patients who are surgical candidates. Furthermore, radiofrequency ablation can potentially decrease the need for frequent imaging/surveillance of the pancreatic tumor (cyst). In patients with immediate prohibitive, but reversible risks for surgery, radiofrequency ablation of a high-risk tumors (cysts) can potentially prevent further progression of the lesion and bridge the time before the need for surgical resection.
• Age \> 18 years
• A diagnosis of a PCN confirmed by EUS-FNA including cyst fluid next generation sequencing (NGS) and/or EUS-guided needle-based confocal laser endomicroscopy (nCLE) and/or EUS- guided through-the-needle biopsy (TTNB)
• The pancreatic cystic lesion (PCL) measures at least 2 cm in diameter on either CT or MRI/MRCP or EUS and demonstrates concerning worrisome and/or high-risk features as defined by International Consensus Guidelines (2017 revised Fukuoka Guidelines)
• The patient is not a surgical candidate. Common clinical scenarios include -
‣ Cirrhosis of the liver (common clinical scenario)
⁃ Advanced ( \>= 75 years) age (common clinical scenario)
⁃ Morbid obesity
⁃ Significant cardiorespiratory comorbidity
⁃ Patient's choice (patient elects for non-surgical management)
⁃ Other significant comorbid conditions that impose prohibitive surgical risks
• Estimated life expectancy of at least 1 year
• Capable of giving written informed consent or has a legally authorized representative (LAR) to consent for them
• Women of childbearing potential must have a negative pregnancy test (serum/urine) on the day of treatment. Pregnancy testing is the routine standard of care practice in the endoscopy laboratory for all patients undergoing endoscopy and sedation for endoscopy
• The patient prefers non-surgical management after consultation with hepato-pancreato-biliary (HPB) surgery
• The patient is not a surgical candidate and has had prior attempts at ablation of the PCN by EUS-guided injection of chemotherapy (Ohio State University \[OSU\] Institutional Review Board \[IRB\] protocol 2020C0198)
