a surgical procedure (total pancreatectomy) with a transplant procedure (islet cell autotransplantation) for the treatment of chronic pancreatitis and benign pancreatic tumors

Conditions: Benign Pancreatic Neoplasm; Chronic Pancreatitis; Recurrent Acute Pancreatitis

Summary: this phase i/ii trial assesses the safety and effectiveness of total pancreatectomy with islet cell autotransplantation for the treatment of patients with long-term pancreatic inflammation (chronic pancreatitis) and non-cancerous (benign) pancreatic tumors. total removal of the pancreas (pancreatectomy) can be used to treat chronic pancreatitis, but it may result in diabetes. an islet cell autotransplantation involves removing cells from a patient's pancreas (the islet cells) and infusing them into the liver. islet cells are responsible for producing hormones like insulin, reducing the occurrence of diabetes in patients undergoing total pancreatectomy. total pancreatectomy with autologous islet cell transplant is an accepted and food and drug administration-approved treatment for patients with chronic pancreatitis. however, patients with chronic pancreatitis and pancreatic tumors have historically not been candidates for this procedure due to concerns of spreading potentially cancerous cells to other parts of the body. this clinical trial evaluates the safety and effectiveness of this treatment in patients with chronic pancreatitis and benign pancreatic tumors.

primary objective: i. to evaluate the oncologic safety of total pancreatectomy with islet cell autotransplantation (tpiat) in chronic pancreatitis patients with benign pancreatic neoplasms. secondary objectives: i. to evaluate postoperative insulin requirements in patients with presumed benign pancreatic neoplasms undergoing tpiat. ii. to evaluate postoperative opiate requirements in patients with presumed benign pancreatic neoplasms undergoing tpiat. iii. to evaluate the postoperative survival of patients with presumed benign pancreatic neoplasms undergoing tpiat. exploratory objectives: i. to evaluate quality of life outcomes in patients undergoing tpiat with presumed benign pancreatic neoplasms. ii. to evaluate subjective pain-related outcomes in patients undergoing tpiat with presumed benign pancreatic neoplasms. outline: patients undergo total pancreatectomy and autologous islet cell transplant intravenously (iv) over 15-60 minutes on day 1. after completion of study treatment, patients are followed up for 2 years.

abstinence) prior to undergoing pancreatectomy and iat. should a participant become pregnant or suspect a pregnancy prior to planned pancreatectomy and iat, the participant should inform their treating physician immediately exclusion criteria: * prior allogenic or autologous islet cell transplantation * underlying liver disease, unless participant has undergone hepatology consultation to evaluate hepatic risk from iat and been deemed low-risk, including: * cirrhosis, defined by either * pathologic diagnosis of cirrhosis or * diagnosis of cirrhosis by hepatology following evaluation prompted by clinical, radiographic, or biochemical evidence of cirrhosis * hepatic steatosis as defined by pathologic examination of the liver or liver magnetic resonance imaging in the absence of pathologic evidence * use of any systemically absorbed steroid (e.g., prednisone but not budesonide) within the prior month * untreated malignancy of a non-pancreatic primary * cytology or biopsy of a pancreatic neoplasm diagnostic for malignancy prior to the time of iat * a pancreatic neoplasm deemed to be at high risk for harboring occult malignancy as assessed by the multi-disciplinary pancreas tumor board and multi-disciplinary chronic pancreatitis conference after comprehensive evaluation of relevant clinical, radiographic, pathologic, and serologic data. features of high-risk neoplasms include the following, however the below items are not to be taken as absolute contraindications to tpiat: * obstructive jaundice in a patient with a pancreatic cystic neoplasm in the head of the pancreas * enhancing mural nodule of any size * main pancreatic duct \>= 5mm * acute pancreatitis with cystic lesion as the only potentially identifiable cause * cyst \>= 3cm, if lesion is a mucinous neoplasm * thickened/enhancing cyst walls * abrupt change in caliber of pancreatic duct with distal pancreatic atrophy on imaging * celiac/portal lymphadenopathy * serum ca19-9 above the institutional upper limit of normal * pancreatic cyst growth rate \>= 5mm every 2 years * cytology suspicious for malignancy * clinical suspicion for main duct involvement based on imaging * evidence of metabolic syndrome, as defined by any 3 of the below features, unless the participant has undergone hepatology consultation to evaluate hepatic risk from iat and been deemed low-risk: * waist circumference more than 40 inches in men and 35 inches in women * elevated triglycerides 150 milligrams per deciliter of blood (mg/dl) or greater * reduced high-density lipoprotein cholesterol (hdl) less than 40 mg/dl in men or less than 50 mg/dl in women * elevated fasting glucose of 100 mg/dl or greater * blood pressure values of systolic 130 mmhg or higher and/or diastolic 85 mmhg or higher * multifocal or large pancreatic neoplasms such that an insufficient volume of remnant pancreas would remain for the patient to benefit from iat following resection of the neoplasms in the opinion of the multi-disciplinary chronic pancreatitis board * history of allergic reaction to human albumin preparations * demonstrated medical non-compliance * patient unsafe to undergo the required pancreatectomy procedure in the opinion of the attending surgeon and/or anesthesiologist * patients deemed not suitable for the iat follow-up protocol by any member of the multi-disciplinary iat care team * any alcohol or tobacco use within 6 months of study enrollment * financial, logistic, or insurance constraints preventing adequate and timely pre-operative evaluation, case scheduling, or post-operative monitoring/follow-up * pregnant individuals are excluded from this study because invasive abdominal surgical procedures such as pancreatectomy have the known potential to cause pregnancy loss
