Integrated Cancer Repository for Cancer Research

The iCaRe2 is a multi-institutional resource created and maintained by the Fred \& Pamela Buffett Cancer Center to collect and manage standardized, multi-dimensional, longitudinal data and biospecimens on consented adult cancer patients, high-risk individuals, and normal controls. The distinct characteristic of the iCaRe2 is its geographical coverage, with a significant percentage of small and rural hospitals and cancer centers. The iCaRe2 advances comprehensive studies of risk factors of cancer development and progression and enables the design of novel strategies for prevention, screening, early detection and personalized treatment of cancer. Centers with expertise in cancer epidemiology, genetics, biology, early detection, and patient care can collaborate by using the iCaRe2 as a platform for cohort and population studies.

Tissue Adhesive Glue Modified Cyanoacrylate (Glubran® 2) in Soft Pancreas

This is a single-center, randomized controlled trial comparing the efficacy of pancreaticojejunostomy with modified N-butyl-2-cyanoacrylate(Glubran® 2) versus standard pancreaticojejunostomy without cyanoacrylate in preventing postoperative pancreatic fistula (POPF) in patients undergoing pancreaticoduodenectomy with soft pancreatic texture. The primary endpoint is the incidence of postoperative pancreatic fistula at 30 days post-surgery, as defined by the International Study Group on Pancreatic Fistula (ISGPF) criteria.Secondary outcomes include surgical complications and length of hospital stay. The study will enroll approximately 194 patients at a single center.

Treatment of Distal Malignant Biliary Obstruction by Uncovered, Partially Covered, or Fully Covered Metal Stents

The goal of this randomized controlled trial is to compare uncovered, partially covered, and fully covered self-expandable metal stents (SEMS) in the palliative treatment of distal malignant biliary obstruction in a Swedish multicenter study. The main questions it aims to answer is: Is the stent patency rate different depending of stent type? Is the stent patency time different depending of stent type? Is the patient survival different between the groups? Which complications are seen, and do they differ between the groups? Are there different mechanisms behind the stent failure depending on stent type? Patients will at ERCP, with a guidewire passed through the stenosis in the bile duct, be allocated to either uncovered, partially covered, and fully covered (SEMS). Totally, 450 patients will be recruited, 150 in each study arm, according to the power analysis. Patients will be followed in a monthly surveillance by a study nurse up to 12 months after stent insertion. Endpoints are: alive after 12 months with a patent stent, death with a patent stent, stent dysfunction with a subsequent intervention i.e. repeated ERCP or PTC = "objective stent failure", stent dysfunction, jaundice or cholangitis, but not intervention has been undertaken due to a poor condition of the patient, "clinical stent failure", the patient has undergone curative surgery or a bilio-enteric by-pass (a gastro-enteroanastomosis or a duodenal stent is not a reason for exclusion), the patient refuses further follow-up.

Monitoring of patIents With Microdialysis Following Pancreaticoduodenectomy

A pancreaticoduodenectomy is performed in patient with pancreatic cancer. The most common and serious complication is leakage between the intestine and the remnant pancreas after this procedure. It occurs in 20-30%. The result is often prolonged hospital and ICU stay, reoperations and deaths (3-5%). To detect a leakage early before the patient becomes seriously ill, thereby initiating treatment is therefore very important. By inserting a thin microdialysis catheter near the anastomosis between pancreas and intestine before closure of the abdominal wall, the investigators will analyze substances such as lactic acid, pyruvate, glycerol, etc. and if these substances may reveal anastomosis leakage at an early stage. Observational studies have shown that if a leakage occurs, glycerol concentration in the microdialysate will rise significant after few hours, and changes in lactic acid and pyruvate values will change as a sign of inflammation. The investigators want to conduct a randomized study comparing patients undergoing pancreaticoduodenectomy and using microdialysis in half of the included population.

Modulated Mid-frequency Whole-body Electromyostimulation and Nutritional Therapy in Gastrointestinal Cancer Patients

The purpose of this study is to assess the efficacy of modulated mid-frequency whole-body electromyostimulation (WB-EMS) combined with nutritional therapy in patients with gastrointestinal cancer.

Quebec Pancreas Cancer Study

The Quebec Pancreas Cancer Study is a prospective clinic-based study consisting of clinical, family history and epidemiologic data, with accompanying biospecimens, from patients diagnosed with either pancreas cancer, a related cancer or a related pre-cancerous condition, and their families.
