Brief Summary

Pancreatic cancer remains a devastating disease with an average 5-year survival rate of about 3-5%. Previous retrospective studies showed that perioperative epidural block and/or dexamethasone are associated with improved outcome after cancer surgery. This randomized trial aims to investigate the effect of perioperative epidural block and/or dexamethasone on long-term survival in patients following pancreatic cancer surgery.

Detailed Description

Pancreatic cancer is the fourth leading cause of cancer-related death in the world, and is estimated to become the second one in 2030. For patients with resectable pancreatic cancer, radical surgery is the first-line therapy. However, the clinical outcomes remain poor even after radical resection, as the incidence of postoperative morbidity is up to 50% and the 5-year survival rate remains below 30%.

For patients undergoing major intraabdominal surgery, epidural block may provide advantages by blocking the afferent nociceptive stimuli, providing better pain relief, decreasing opioid consumption, and alleviating stress response. These effects may be helpful in preserving immune function. Some retrospective studies showed that epidural block is associated with delayed cancer recurrence/metastasis and improved survival after cancer surgery.

Low-dose dexamethasone is frequently used to prevent postoperative nausea and vomiting. Recent evidences from retrospective studies suggest that perioperative dexamethasone may also affect long-term outcome after cancer surgery. For example, in patients undergoing lung cancer surgery, intraoperative dexamethasone is associated with improved recurrence-free and overall survival. Similar results are also reported in patients after pancreatic cancer surgery.

The investigators hypothesize that perioperative epidural block and dexamethasone may improve survival in patients after radical pancreatic surgery. The purpose of this study is to investigate whether perioperative epidural block and/or dexamethasone can improve 2-year survival in patients after pancreatic cancer surgery.

Arm && Interventions

Group	Intervention	Description
Epidural block	Epidural block	Patients in this group receive combined epidural-general anesthesia (0.375% ropivacaine for epidural block), without perioperative dexamethasone. Patient-controlled epidural analgesia is provided after surgery.
Epidural block+Dexamethasone	Epidural block	Patients this group receive dexamethasone (10 mg) before anesthesia induction and combined epidural-general anesthesia (0.375% ropivacaine for epidural block). Patient-controlled epidural analgesia is provided after surgery.
Dexamethasone	Dexamethasone	Patients in this group receive dexamethasone (10 mg) before anesthesia induction and general anesthesia, without epidural block. Patient-controlled intravenous analgesia is provided after surgery.
Epidural block+Dexamethasone	Dexamethasone	Patients this group receive dexamethasone (10 mg) before anesthesia induction and combined epidural-general anesthesia (0.375% ropivacaine for epidural block). Patient-controlled epidural analgesia is provided after surgery.

Primary Outcome Measures

Name	Time	Method
2-year overall survival	Up to 2 years after surgery.	2-year overall survival

Secondary Outcome Measures

Name	Time	Method
Postoperative gastrointestinal complications.	Up to 30 days after surgery.	Rate of postoperative gastrointestinal complications.
Overall postoperative complications.	Up to 30 days after surgery.	Rate of overall postoperative complications.
Length of stay in hospital after surgery.	Up to 30 days after surgery.	Length of stay in hospital after surgery.
All-cause 30-day mortality.	Up to 30 days after surgery.	Rate of all-cause 30-day mortality.
2-year progression-free survival	Up to 2 years after surgery.	Cancer progression is evaluated according to the Response Evaluation Criteria in Solid Tumors (RECIST) guideline version 1.1.
Quality of life in 1- and 2-year survivors.	At the end of the first and second year after surgery.	Quality of life is assessed with the European Organization for Research and Treatment of Cancer Quality of Life Questionaire (EORTC QLQ)-PAN26. It is a 26-item questionnaire that evaluates 9 symptoms and 5 emotional difficulties related to pancreatic cancer. Each item is scaled 0-100. High scores indicate worse symptoms and poorer quality of life.
Hospital readmission within 2 years after surgery.	Up to 2 years after surgery.	Rate of hospital readmission within 2 years after surgery.
