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

Official title: 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

Run by Insel Gruppe AG, University Hospital Bern · NCT06801899 · Data updated 2026-11-12

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.

Is this trial a fit for you?

Likely a 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.

Probably 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.

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.

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 gone: 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.

Inclusion Criteria:

* Adult patients (age ≥ 18 years) scheduled to undergo PD for highly suspected or histologically proven, resectable pancreatic ductal adenocarcinoma (PDAC), distal cholangiocarcinoma (DCC), and/or ampullary cancer (pancreaticobiliary type)
* Suspected pancreas anastomosis at high-risk for development of a postoperative pancreatic fistula (POPF) (grade "D" according to Schuh et al. (29): Estimation by CT scan, MRI, and/or Endoscopic Ultrasound
* Written informed consent

Exclusion Criteria:

* Duodenal carcinoma, ampullary cancer (intestinal type), neuroendocrine tumors, benign tumors, chronic pancreatitis
* Medical conditions that do not allow appreciation of the nature, scope, and possible consequences of the trial as judged by the investigator

* Inability to follow the study procedures, e.g., due to psychological disorders, dementia, etc.
