简要总结
Pancreatic cancer is the second most common gastrointestinal malignancy. Abdominal discomfort is a main symptom in patients with pancreatic cancer. Approximately 75% have pain at diagnosis and over 90% in advanced stages. Pain control is an important part of the plan of care for patients with pancreatic cancer.. The celiac plexus is a group of nerves that supply organs in the abdomen. EUS-guided celiac plexus neurolysis (EUS-CPN) has been widely used for pain management in patients with pancreatic cancer. Radiofrequency ablation of celiac ganglia or celiac plexus (EUS-RFA) is also being performed to alleviate abdominal pain in pancreatic cancer patients. However currently no comparative studies exist comparing EUS-CPN with EUS-RFA. The purpose of the study is to compare EUS-CPN with EUS-RFA for pain management in pancreatic patients, in order to determine which technique is better at improving pain in pancreatic cancer patients.
详细描述
Pancreatic cancer is the second most common gastrointestinal malignancy and fourth leading cause of cancer mortality. The incidence in the US is estimated at 8.8 per 100,000 population with 30,000 new cases diagnosed annually. The prognosis of unresectable pancreatic cancer is poor; overall 1 and 5-year survivals do not exceed 20 and 4%, respectively. For the minority of patients (15%) who are resectable at diagnosis, the median survival is 10-20 months, with 5-year survival of 10-25%.
Abdominal discomfort is a predominant symptom in patients with pancreatic cancer. Approximately 75% have pain at diagnosis and over 90% in advanced stages. Therefore a major aspect of palliation is provision of adequate pain control. The standard approach to pain management is based on the World Health Organization (WHO) 3-step ladder, beginning with non-opioid analgesics (e.g. non-steroidal anti-inflammatory drugs (NSAIDs) or acetaminophen), followed by weak opioids and then finally strong opioids as necessary. Virtually all patients require escalating doses of opioids during their disease. Adjuvant therapies, including other medications (e.g. trazodone, tricyclic anti-depressants, and bisphosphonates), palliative radionucleotides, external beam radiation, or chemotherapy may also be useful for symptomatic control.
In the last 10 years, EUS-guided celiac plexus neurolysis (EUS-CPN) has been widely practiced for alleviation of pain in patients with pancreatic cancer and has been shown to be effective. At our institution, radiofrequency ablation (EUS-RFA), which involves ablation of celiac ganglia or celiac plexus using a radiofrequency catheter, is being performed to alleviate abdominal pain in pancreatic cancer patients. However currently no comparative studies exist comparing EUS-CPN with EUS-RFA for pain alleviation in pancreatic cancer patients.
In this randomized trial, the investigators will be comparing EUS-CPN with EUS-RFA for pain alleviation in pancreatic patients, in order to determine which technique is better at improving pain in pancreatic cancer patients.

研究组 & 干预措施
Celiac Plexus Neurolysis
CPN will be undertaken at the celiac space which is located between the aorta and the celiac artery origin. A 22 or 19-gauge Fine Needle Aspiration (FNA) needle is used, and its tip is placed slightly anterior and cephalic to the origin of the celiac artery. Aspiration is first performed using a syringe to ensure that vascular puncture has not occurred. 10 mL Bupivacaine is injected first, followed by 20 mL of 98% alcohol.
干预措施: Celiac Plexus Neurolysis (Other)
Radiofrequency Ablation
Once the celiac ganglia are identified on EUS, a 19-gauge FNA needle is inserted into the center of the ganglion or area of celiac plexus under EUS guidance. The radiofrequency (RF) probe (EMcision, Montreal, Canada) is advanced through the FNA needle. Radiofrequency ablation is performed via the probe for 90 seconds, followed by a 90 second rest and repeated as required.

结局指标
主要结局
Subject assessment of abdominal pain
时间窗: Baseline to 4 week follow up
Abdominal pain will be assessed with pain scores from the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Pancreatic Cancer module (QLQ-PAN26). The questionnaire has 26 questions with scoring ranging from a minimum of 26 to a maximum of 104. The higher the score, the worse the subject's quality of life rating.
次要结局
- Narcotic Use(Initial visit; 2 week follow up; 4 week follow up)
- Crossover to alternate technique(48 hours post procedure; 2 week follow up; 4 week follow up)
- Adverse effects, and endoscopic adverse events(48 hours post procedure; 2 week follow up; 4 week follow up)
- Survival rate(2 week follow up; 4 week follow up)
- Subject assessment of Quality of Life.(Baseline; 2 week follow up; 4 week follow up)
- Pain per the VAS tool.(Baseline; 48 hour post procedure; 2 week follow up; 4 week follow up)
