18-1505 - Review of IVC Filter Practice Patterns
PI: Johnathan Lindquist, MD
The purpose of this study is to retrospectively evaluate clinical outcomes, practice patterns, and risk factors specific to different patients. This study looks at both inpatients and outpatients who have had IVC filters placed or retrieved. The main interest is to compare the filters and filter retrieval devices and their outcomes within UCH. Over 25 years of retrospective data will be evaluated and used to document adjunctive/advanced retrieval techniques, implanting factors on filter duration, and filter placement/retrieval complications.
18-0392 - Tomosynthesis Mammographic Imaging Screening Trial (TMIST)
PI: Dulcy Wolverton, MD
The purpose of TMIST is to determine whether tomosynthesis (TM) can or should replace digital mammography (DM) to screen for breast cancer. Healthy female patients are randomly assigned to either the 2D screening (DM) arm or the 3D screening (TM) arm over the course of 5 years, with an additional 3 years of follow up, to determine the effectiveness of the technology. If it is determined that tomosynthesis is more effective in finding important breast cancers, i.e., those that are more likely to advance and kill women, then those in the (TM) arm will see a decrease in these cancers compared to the (DM) arm. This study will look at the utility of the different screening tools as well as the advantages and disadvantages of each screening method.

16-0812: Radiation-Emitting SIR-Spheres in Non-resectable (RESIN) Liver Tumor Patient Registry
PI: Robert Ryu, MD
The purpose of the RESiN registry is to collect information about patients who have primary and secondary liver cancer receiving SIR-Spheres as part of their overall oncologic management. SIR-Spheres is a medical device containing Yttrium-90 (Y-90), a radioactive material that has been used to shrink liver tumors. The RESiN registry will collect information including: patient demographics (sex, age, race/ethnicity); previous, concurrent and follow-up oncologic treatments; details of Y-90 treatment; and outcomes and complications.
The information generated will help doctors better understand treatment patterns involving Y-90 therapy and gain insight in the long-term outcomes for patients. It will also guide future research for using Y-90 therapy, especially for those conditions where data are currently limited.
15-0743: Prospective Study of Magnetic Resonance Imaging (MRI) and Multiparameter Gene Expression Assay in Ductal Carcinoma In Situ (DCIS)
PI: Wei Shin Wang, MD
The purpose of this study is to evaluate advanced imaging to more accurately identify the anatomic extent of the disease with molecular characteristics of Ductal carcinoma in situ (DCIS) and to more accurately characterize the biology of the disease rather than just the symptoms and pathology of the disease. Ductal carcinoma in situ (DCIS) is a non-invasive cancer where abnormal cells have been found in the lining of the breast milk duct. The atypical cells have not spread outside of the ducts into the surrounding breast tissue. This integrated anatomical and biological characterization from the Magnetic Imaging Resonance (MRI) of DCIS lesions is expected to better stratify the need for therapeutic interventions, while maintaining excellent clinical outcomes, facilitating more informed shared decision making, and preserving quality of life.

14-2053: Clinical Validation of a Predictive Model for the Presence of Cervical Lymph Node Metastasis in Papillary Thyroid Cancer
The purpose of this study is to compare the accuracy of two methods of lymph node evaluation using ultrasound in patients who have papillary thyroid cancer (PTC): research method vs. standard method. The standard method is what is usually performed as standard of care where the radiologist evaluates the ultrasound images of the lymph nodes overall and decides whether each node seen should or should not be biopsied. In the research method, a radiologist evaluates the ultrasound images of the lymph nodes and uses a small, specific checklist of ultrasound appearance to determine whether each node should or should not be biopsied. Information from both of these evaluation methods is recorded to determine which method more accurately identifies the cancer in the lymph node.

10-1335: ACRIN 6690: A Prospective, Multicenter Comparison of Multiphase Contrast-Enhanced CT and Multiphase Contrast- Enhanced MRI for Diagnosis of Hepatocellular Carcinoma and Liver Transplant Allocation
The purpose of this study is to determine and compare the accuracy of computed tomography (CT) scans and magnetic resonance imaging (MRI) in diagnosing liver cancer. The most effective way to treat patients with liver cancer and other liver disease may be liver transplantation. With improved imaging methods, the study doctors believe they can improve current methods of listing patients with advanced liver disease on the waitlist for liver transplant. To discover which imaging method gives a clearer picture of liver disease, the images from both the CT and MRI scans will be compared to the actual liver after it is removed during transplant surgery and examined.

15-1608: Registry of Angiovac Procedures In Detail Outcomes Database
For more information about this trial, please visit http://investors.angiodynamics.com/releasedetail.cfm?releaseid=926187
PI: Paul Rochon, MD
PRESERVE is a large, multi-center clinical trial that aims to prospectively evaluate the safety and efficacy of inferior vena cava (IVC) filters. IVC filters are small metal devices that are placed in the IVC to stop large blood clots from traveling to the lungs. The purpose of this study is to get information about why these filters are used, when they are removed, and to collect health information about patients who have these filters placed. Patients who are enrolled in this study will have an IVC filter placed and will be followed for up to 2 years or 1 month following IVC filter removal, whichever comes first.
