A Study to Establish Novel Tumor Models Using Scant Tumor Specimens from Solid Tumor Patients
Rochester, MN; Scottsdale/Phoenix, AZ
The objective of this research is to determine the feasibility of establishing organoid tumor models using scant solid tumor tissues obtained by image-guided core needle biopsy procedures during routine clinical care. The routine clinical biopsy may be by image-guidance, endoscopic-guidance (e.g., EGD, colonoscopy, bronchoscopy), direct visualization (e.g., skin biopsy) and surgical exploration. Once established, the tumor organoids’ response to anti-cancer agents will be assessed. If proven feasible, this technique can potentially be integrated into routine clinical care of solid tumor patients and help guide the treatment of the donor patient in the clinic.

A Study of Biomarkers to Distinguish Benign from Cancerous Thyroid Tumors
Rochester, MN
The purpose of this study is to evaluate microRNA biomarkers in the blood and fine-needle aspirate biopsies of thyroid nodules to determine their usefullness in pre-operative diagnosis, in particular to distinguish benign from cancerous thyroid nodules.

Endoscopic Ultrasound Guided Fine Needle Biopsy (EUS-FNB-SC) Using a Novel Fork Needle
Jacksonville, FL
This is a clinical trial to compare two needles used in biopsy techniques to acquire tissue from pancreatic cancer. The hypothesis is that the tissue yield, as measured by tumor DNA and cellular material is superior for Flexible Needle Biopsy (FNB) compared with conventional Fine Needle Aspiration (FNA). Specifically, FNB will increase the proportion of cases in which sufficient DNA is obtained to allow genomic profiling and whole exome sequencing.

Submandibular Gland Needle Core Biopsy and Skin Punch Biopsy as Tissue Biomarkers for the Diagnosis and Monitoring of Disease Progression of Parkinson’s Disease and REM Sleep Behavior Disorder
Scottsdale/Phoenix, AZ
Determine 1) the magnitude of SMG and skin a-syn density change over time, 2) the
improvement in adequate tissue acquisition doing bilateral SMG biopsies, 3) any laterality differences between
SMG gland a-syn density, 4) correlate a-syn density and changes in density between SMG and skin biopsies
Specific Aim 1. Determine, with bilateral submandibular gland (SMG) biopsies in 30 clinically
diagnosed subjects with Parkinson’s disease (PD) and 20 clinically probable REM sleep behavior
disorder (RBD) subjects whether bilateral biopsies improve the rate of acquisition of adequate
glandular tissue, whether alpha-synuclein (a-syn) SMG pathology ...

Transcutaneous Submandibular Gland Biopsy: Feasibility of Repeat Biopsy as a Progression Marker for Parkinson's Disease
Scottsdale/Phoenix, AZ
The purpose of this study is to perform biopsies of one of the glands that make saliva. The biopsied tissue will then be analyzed to see if it has changes that occur in Parkinson's disease. This study will determine whether it is possible to do a second biopsy a few years after a previous biopsy and determine whether there are changes in the biopsy that would allow for analysis of disease progression.

A Study to Evaluate the Patient Experience Regarding Image-Guided Percutaneous Breast Biopsy
Jacksonville, FL
The purpose of this study is to to better understand the concerns of patients prior to a breast biopsy so that we may improve our practice and ultimately enhance overall patient experience.

A Study of Disease Risk Caused by Tumor Particles Getting into the Blood from Endoscopic Ultrasound Guided Fine Needle Aspiration
No Locations
The purpose of this study is to assess the risk for cancer spread caused by the leaking of tumor particles into the blood from the biopsy procedure endoscopic ultrasound guided fine needle aspiration.

A Study to Assess the Utility of Cell Count and Differential of Aspirated Fluid in the Diagnosis of Native Vertebral Osteomyelitis
Rochester, MN
The purpose of this study is to assess the utility of cell count and differential from aspirated fluid obtained via CT guided needle aspiration biopsy of vertebral bone and intervertebral disc space in the diagnosis of native vertebral osteomyelitis (NVO).
