Curative management of locally resectable invasive adenocarcinomas located in the cephalic region of the pancreas (pancreas, duodenum and ampulla of Vater) requires a pancreaticoduodenectomy followed by adjuvant chemotherapy. Pancreaticoduodenectomy is a major surgery that often leads to major complications including approximately 20% of relevant clinical postoperative pancreatic fistula.
Postoperative complications following pancreaticoduodenectomy can lead to early discontinuation of the complete oncologic strategy, i.e., chemotherapy for malignancy is performed in only about a third of patients who experienced a grade C fistula.
A total pancreatectomy rather than a pancreaticoduodenectomy is an alternative procedure that involves the complete and definitive resection of all pancreatic tissue, eliminating any risk of postoperative pancreatic fistula but is associated with unavoidable endocrine insufficiency and potentially severe metabolic complications, such as "brittle diabetes".
Total Pancreatectomy following by intraportal Islet AutoTransplantation (TPIAT) can prevent "brittle diabetes" and improve the quality of life. The endocrine islets can be isolated from the pancreatic surgical specimen with standardized procedures and transplanted in the liver through intraportal infusion, in absence of immunosuppression and allow adequate control of glucose metabolism with a reduced need for exogenous insulin and an effective graft function in 70% of cases at 3 years Thereby, the investigators hypothesize that total pancreatectomy with intraportal Islet autotransplantation rather than classical pancreaticuduodenectomy, in patients with high-risk of postoperative fistula will increase the rate of complete access to adjuvant chemotherapy, while maintaining an adequate metabolic control.

Single group
total pancreatectomy
Procedure/SurgeryThe total pancreatectomy will be performed in two steps: The pancreatectomy will begin by a standard pancreaticoduodenectomy procedure. The section margin will be sent for intraoperative histological analysis to confirm the absence of invasion of the left remnant pancreas. When absence of tumor invasion is confirmed and the high-risk of postoperative pancreatic fistula is validated intraoperatively, the extended left distal pancreatectomy will be performed, with splenic preservation when possible. Then, the left side of the pancreas will be resected and cooled (4-6°) in the preservation solution and shipped to Lille Biotherapy platform to perform islet isolation and purification. The reconstruction after total pancreatectomy will be done as usually performed by center expert surgeon.
intraportal islet autotransplantation
Biological/VaccineThe final islet preparation will be cultured and shipped 48 hours after total pancreatectomy from the Lille laboratory to the surgical center, and finally transplanted into the patient through a venous catheter placed in the portal trunk (91% of the total islet mass) and at the same time, a small fraction of the isolated islet (5% of the total islet mass) will be transplanted into the forearm muscle.
the rate of patients who have completed the chemotherapy planned
success is defined when patients treated with TPIAT will have completed the adjuvant systemic chemotherapy initially approved and planned by the local multidisciplinary expert team according to current international guidelines
Rate of postoperative complications related to total pancreatectomy.
postoperative complication will be evaluated with Dindo Clavien classification
Rate of complications related to islet transplantation during the study
complications related to islet transplantation will be reported according to CTCAE v5.0.
Mean time (in weeks) between TPIAT and adjuvant systemic chemotherapy.
the time in weeks between TPIAT procedure and the adjuvant systemic chemotherapy will be reported
Rate of patients with cancer recurrence
The cancer recurrence will be assessed according standard of care imaging (Thorax multi-detection Computed Tomography, Abdomino-pelvis imaging : Mutli-detection Computed Tomography OR Magnetic Resonance Imaging) through the follow up using the Recist 1.1 criteria
