Filter this list of studies by location, status and more.

1. Whole Exome Sequencing and Other Emerging Technologies of Endoscopic Ultrasound Cytopathology

   Rochester, Minn.

   The purpose of this research study is to gather information on the feasibility of performing novel molecular analysis on Endoscopic Ultrasound acquired cytologic material and to assess molecular changes in cytology samples to see if that may aid treatment decision planning for future patients.

2. Mayo Clinic Health TAPESTRY: Use of Genomic Sequencing in Clinical Practice

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

   Tapestry is a Mayo Clinic research study, which includes receiving genetic sequencing data from Helix, up to the full whole exome dataset. The goal of this study is to provide: (i) an immediate interpretation of ancestry/genealogy and several non-disease traits, as well as, clinically actionable variants for an inherited form of high cholesterol called familial hypercholesterolemia (FH), breast and ovarian cancer (HBOC), and Lynch syndrome to each participant; (ii) an additional subset of focused clinically actionable genetic findings, such as, certain types of hereditary cancers, hereditary heart conditions and severe responses to certain medications, will be returned to the provider and to the participant, via the provider, genetic counselor consultation, and/or Mayo Clinic research interpretation; (iii) storing of genomic and phenotypic data for future research analysis.

3. A Study to Evaluate Voice-enabled Artificial Intelligence to Diagnosis Hepatic Encephalopathy

   Rochester, Minn.

   early detection of hepatic encephalopathy

4. Chemotherapy Alone or Chemotherapy Plus Radiation Therapy in Treating Patients with Locally Advanced Rectal Cancer Undergoing Surgery

   Rochester, Minn., Scottsdale/Phoenix, Ariz.

   The standard treatment for locally advanced rectal cancer involves chemotherapy and radiation, known as 5FUCMT, (the chemotherapy drugs 5-fluorouracil/capecitabine and radiation therapy) prior to surgery. Although radiation therapy to the pelvis has been a standard and important part of treatment for rectal cancer and has been shown to decrease the risk of the cancer coming back in the same area in the pelvis, some patients experience undesirable side effects from the radiation and there have been important advances in chemotherapy, surgery, and radiation which may be of benefit. The purpose of this study is to compare the effects, both good and bad, of the standard treatment of chemotherapy and radiation to chemotherapy using a combination regimen known as FOLFOX, (the drugs 5-fluorouracil (5-FU), oxaliplatin and leucovorin) and selective use of the standard treatment, depending on response to the FOLFOX. The drugs in the FOLFOX regimen are all FDA (Food and Drug Administration) approved and have been used routinely to treat patients with advanced colorectal cancer.

5. Tissue Collection for Patients with Cancers other than Hepatobilairy Cancers with Metastasis to the Liver

   Rochester, Minn.

   The goal of this study is to develop a resource (bank) of biospecimens (blood, tissue) from patients having cancers that metastasis to the liver. The purpose of the resource bank is to facilitate studies on the pathogenesis of cancers metastasizing to the liver and also in order to assess the ability of new tests to detect early cancer in the cohort of patients undergoing routine surveillance for cancer. The biospecimens will include cultures of tumor cells and tumor-associated non-malignant cells, as well as xenografts established from freshly isolated metastatic cancers in immunodeficient mice. We plan to administer a risk factor questionnaire to facilitate identification of risk factors for development of metastatic liver cancer. The study will also  determine survival of patients from time of diagnosis.

    

6. Biobank for Cholestatic Liver Diseases

   Rochester, Minn.

   This study is a biobank of specimens and clinical data for use in current and future research to better understand the cholestatic liver diseases primary biliary cirrhosis/cholangitis (PBC) and primary sclerosing cholangitis (PSC).

7. Cystic Kidney and Liver Disease Biobank

   Rochester, Minn.

    

   This research study is being done to create a collection of biospecimens (blood, urine, cyst fluid, bile, kidney or liver tissue, etc.) that can be used to facilitate the conduction of research on polycystic kidney and/or liver disease.

8. Fecal Microbiome Transplant National Registry

   Rochester, Minn.

   The overarching goal of the FMT registry is to expand knowledge and optimize practice in the transplantation of fecal microbiota or other gut-related-microbiota products.

9. Phase II Study of EUS-guided Verteporfin PDT in Solid Pancreatic Tumors

   Rochester, Minn.

   The goal of project is to target of locally advanced pancreatic cancer (LAPC) with a photodynamic therapy (PDT) to evaluate response of tumor.

10. Nitrous Oxide For Endoscopic Ablation of Refractory Barrett's Esophagus

    Rochester, Minn.

    The purpose of this multicenter, prospective, single arm, non-randomized clinical trial to evaluate the safety and efficacy of the C2 CryoBalloon Focal Ablation System (CbFAS) for the treatment of persistent dysplasia or intestinal metaplasia (IM) in the tubular esophagus after 3 or more radiofrequency ablations (RFA) for dysplastic BE, or <50% eradication of Barrett's Esophagus (BE) after 2 RFA treatments.
