1. A Study To Evaluate Hyperthermic Intraperitoneal Chemotherapy To Treat Patients With Pancreatic Cancer And Peritoneal Metastasis

   Rochester, Minn.

   The primary purpose of this study is to assess short-term morbidity and disease-free survival outcomes for patients with pancreatic adenocarcinoma with limited low volume peritoneal metastasis or positive peritoneal cytology undergoing hyperthermic intraperitoneal chemotherapy.

    

    

2. A Study To Detect Pancreatic Cancer Using Circulating Tumor Markers

   Rochester, Minn.

   The primary purpose of this study is to select and validate candidate methylated DNA markers (MDMs) (individually and in combined panels) for the detection of pancreative ductal adenocarcinoma (PDAC). The potential complementary value of mutant KRAS and CA19-9 will also be evaluated.

3. A Study to Assess Outcome of Hospitalization for Cirrhosis Patients

   Rochester, Minn., Jacksonville, Fla., Scottsdale/Phoenix, Ariz.

   The purpose of this study is to evaluate the outcome of hospitalization related to the presence of cirrhosis. We are participating in optional blood, saliva, urine, ascitic fluid and stool collection. 

    

    

4. Gastrointestinal-Related Cancers and Diseases

   Rochester, Minn.

   The purpose of applying to the Institutional Review Board (IRB) for the collection of GI-related tissue is to enable comprehensive molecular investigations into the mechanisms underlying gastrointestinal cancers and diseases.

5. Prospective Tissue Collection of Hepatic Epithelia:

   Rochester, Minn.

   The purpose of this research study is to improve our understanding of normal liver and gallbladder function and liver and gallbladder diseases including PBC, PSC, ADPKD (Autosomal Dominant Polycystic Kidney Disease), and ARPKD (Autosomal Recessive Polycystic Kidney Disease) and gallbladder inflammation (cholecystitis).

    

    

6. A Colon Bank for Early Detection of Colon Cancer

   Rochester, Minn.

   The purpose of this study is to establish a biobank of samples (blood and stool) to support the development of non-invasive tests for early detection of colon cancer and its precursors.

7. A Study of Measurable Ultrasound Imaging Biomarkers of Crohn's Disease

   Rochester, Minn.

   The purpose of this study is to assess the effectiveness of a new multi-parameter ultrasound technology for evaluation of Crohn’s disease.

8. A Study Of A New Molecular Approach To Blood DNA Screening For Cancer

   Rochester, Minn.

   The primary aim of this study is to evaluate the distribution of marker levels determined by this multi-marker, multi-compartment blood DNA test approach across persons without known cancer or precancer.

9. A Study to Understand the Mechanisms of Normal and Disordered Defection

   Rochester, Minn.

   The purpose of this study is to compare rectal emptying and rectoanal pressures in healthy people and DD. Our hypotheses are that (i) the rate and amount of rectal emptying is higher in healthy people than in patients with DD, (ii) some patients with symptoms of DD will have a normal balloon expulsion test but reduced rectal emptying measured with fecomanoflowmetry, and (iii) compared to healthy people, the rectal pressure increment and/or anal relaxation is reduced in patients with DD.
    

10. A Study to Evaluate Colorectal Polyps with Dietary Inflammation During Colonoscopy

    Jacksonville, Fla.

    Colorectal cancer is the third most commonly diagnosed cancer in both men and women in the United States (1). Colorectal cancer arises from colonic polyps. The major types of polyps associated with colorectal cancer development are adenomatous (tubular which is most common and other types are villous and tubulovillous) and serrated (hyperplastic, sessile or traditional) polyps with varying degrees of dysplasia (2). Hyperplastic polyps are common but they have a low malignancy potential (3). There is evidence that colonic inflammation plays a major role in colon polyp and colorectal cancer development. For example, inflammatory bowel disease is a major predisposing factor for colorectal cancer occurrence, implicating inflammation in the development of colorectal cancer (4). In addition,  obesity, a chronic inflammatory state, is associated with increased colorectal cancer risk (5). However, the use of anti-inflammatory agents in the prevention of colorectal cancer is controversial, although there is some suggestion that its use may lower colorectal cancer risk (6,7). Diet may affect cytokine levels and inflammation (8). Diet rich in trans-fat and sugar has been shown to increase pro-inflammatory cytokines IL-6 and TNFα (9, 10) and the Mediterranean Diet has been shown to decrease inflammatory cytokines (11) and decrease the risk of colon cancer in an UK study (12). Recently, the EDII was developed and validated to assess inflammatory potential of diet based on the Food Frequency Questionnaire (FFQ) (13).  Here we propose to investigate the association between diet-derived inflammation, as measured by the EDII, risk of colon polyps during screening colonoscopy and colorectal cancer development.
