Total versus partial pancreas removal for cancers of the pancreatic head, distal bile duct, and ampulla

ToPanc Trial: Survival After Total Versus Partial Pancreaticoduodenectomy for Adenocarcinoma of the Pancreatic Head, Distal Cholangiocarcinoma, and Ampullary Cancer: a Multi-centric Randomized Controlled Trial

Not applicable Interventional Insel Gruppe AG, University Hospital Bern · NCT06801899

This research will see if removing the entire pancreas instead of just the head improves survival without lowering quality of life for people with cancers of the pancreatic head, distal bile duct, or ampulla who are at high risk of a postoperative pancreatic leak.

What this trial studies

This randomized interventional trial compares total pancreatectomy (removal of the whole pancreas) to standard partial pancreaticoduodenectomy in adults with resectable pancreatic head, distal cholangiocarcinoma, or ampullary (pancreatobiliary type) cancers judged to have a high-risk pancreatic anastomosis. Patients give informed consent, provide two small blood samples (preoperative and during hospitalization), and complete quality-of-life questionnaires; surgery and routine follow-up occur at participating Swiss centers. The trial measures overall survival and quality of life as primary outcomes, with attention to postoperative pancreatic fistula rates and metabolic consequences such as need for lifelong insulin and enzyme replacement. If randomized, treatments and outcomes will be compared to see whether total pancreatectomy reduces leak-related complications and affects long-term survival and daily functioning.

Who should consider this trial

Good fit: Adults (≥18) scheduled for pancreaticoduodenectomy for suspected or proven pancreatic ductal adenocarcinoma, distal cholangiocarcinoma, or ampullary (pancreatobiliary type) cancer who are judged by imaging to have a high-risk pancreatic anastomosis and who can give informed consent.

Not a fit: Patients with other tumor types (duodenal or intestinal-type ampullary cancers, neuroendocrine tumors), chronic pancreatitis, those not judged high-risk for pancreatic leak, or who cannot tolerate major surgery are unlikely to benefit from this comparison.

Why it matters

Potential benefit: If successful, this approach could improve long-term survival for high-risk patients by preventing pancreatic leaks without worsening overall quality of life.

How similar studies have performed: Total pancreatectomy has been used selectively for advanced cases to avoid leaks, but randomized evidence comparing survival and quality of life versus partial resection in high-risk anastomosis patients is limited, making this comparison relatively novel.
