1. Epidemiology Of Chronic Lymphocytic Leukemia

   Rochester, Minn.

   The overall goals of this study are to evaluate similarities and differences of the known genetic and non-genetic epidemiological factors associated with chronic lymphocytic leukemia (CLL) risk across African Americans, Hispanics, and Caucasian populations.

2. Onvansertib For The Treatment Of Recurrent Or Refractory Chronic Myelomonocytic Leukemia

   Rochester, Minn.

   This phase I trial evaluates the safety, effectiveness, and best dose of onvansertib for the treatment of patients with chronic myelomonocytic leukemia that has come back (recurrent) or that does not respond to treatment (refractory). Onvansertib is a drug that binds to and inhibits an enzyme called PLK1, preventing cancer cell proliferation and causing cell death.

3. MR-Guided Cryoablation Of Prostate Bed Recurrences

   Rochester, Minn.

   The purpose of this research is to see if MR-guided cryoablation can effectively treat prostate tumor recurrences.

4. Differences In Immunological Effects Of Vitamin D Replacement Among African American Prostate Cancer Patients With Localized Versus Metastatic Disease

   Scottsdale/Phoenix, Ariz., Jacksonville, Fla.

   The aims of this study are to evaluate the prevalence of vitamin D insufficiency among B/AA prostate cancer patients and to determine the deficits in immunity associated with vitamin D insufficiency. Also, we will evaluate whether the peripheral blood immune cell function is different in B/AA prostate cancer patients with metastatic disease as compared with those with localized disease.

5. A Study of Women undergoing Mammogram Screening at Mountain Park Clinic

   Rochester, Minn., Scottsdale/Phoenix, Ariz.

   The goal of this research is to identify risk profiles of women (with particular emphasis on Hispanic women) for breast cancer based on family history, breast density and other factors known to impact risk such as age, weight, age at menarche, age at birth of first child, etc.

6. Aggressive Malignancy PDX (Avatar) and Cryopreservation Program

   Rochester, Minn.

   The purpose of this study is to assess the ability to successfully create numerous validated patient-derived xenograft (PDX) models from patient tumor specimens obtained at surgery/biopsy via the new Pathology/TRAG cryopreservation protocol, and to generate a large catalog and repertoire of previously unavailable histologically validated PDX.

    

7. Serum Derived From Patient Donors With Paraneoplastic Pemphigus (PNP) to Be Used as a Positive Control for PNP Test

   Rochester, Minn.

   The purpose of this study is to obtain serum from patients with certain rare immunobullous diseases (e.g., paraneoplastic pemphigus, laminin-332 pemphigoid) to replenish a source of positive control for our clinical testing (e.g., Mayo test codes PNPAB, RSBV).  

   • To verify the performance characteristics of anti-Paraneoplastic Pemphigus (PNP) serum and validate its use as a positive control in PNP test.  

   • Serum from patients with PNP will be used for a positive control for the PNP test upon successful validation. 

   Background:  

   For various rare immunobullous diseases, detection of a circulating autoantibody is necessary for accurate diagnosis. As a CLIA requirement, every clinical test run requires positive and negative controls for quality control.  Currently, we use either archived sera or commercially available sera from patients with known relevant immunobullous diseases as a structural integrity positive control of rat bladder or transfected cells, which are the substrates for these indirect immunofluorescence tests.  

   While we have no difficulty locating negative control sera, it is challenging to source positive control sera, due to the rarity of these diseases. Specifically, commercial positive control serum is no longer available for purchase and only limited archived material is available. 

8. Hematology Electronic Consultations (e-Consults) the Mayo Clinic Experience

   Jacksonville, Fla.

   The purpose of this study is to evaluate hematology e-consults to determine their specific use, time to completion, advantages and disadvantages, perceptions from primary care physicians and specialists and economic impact. 

9. 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.

10. Human Blood and Tissues Repository for Neuroscience Research

    Jacksonville, Fla.

    The purpose of this study is to collect adult human blood, cerebrospinal fluid, brain, and spine tissues/fluids at time of surgery in order to conduct future studies of the cellular mechanisms of tissue invasion utilized by brain and spine tumors of the central nervous system (CNS).
