To determine the minimum scan duration for fluorine-18 positron-emitting radioactive isotope-fluorodeoxyglucose (18F-FDG) positron emission tomography (PET)/computed tomography (CT) scans performed on a total-body PET/CT scanner that results in non-inferior image quality to 18F-FDG PET/CT scans performed on a conventional PET/CT scanner. The subject population will be patients being staged for lung cancer, lymphoma, or melanoma.
This is a study to allow continued treatment for participants enrolled in studies of BXQ-350. This study is intended only for those who have completed the required study observation period or are still on treatment upon the closure of their respective BXQ-350 clinical study. The additional treatment is optional and voluntary.
This research aims to explore the relationship between hormonal receptor expression and the clinical and histopathological characteristics of meningiomas. The underlying hypothesis is that hormonal receptor expression, as well as the methylation profile of their gene promoters, are associated with specific aspects of meningiomas and patients' clinical outcomes. The main objective is to study the correlation between the immunohistochemical expression of hormonal receptors and clinicopathological data. The secondary objectif is to study the correlation between the methylation profile of hormonal receptor gene promoters and their...
It has been suggested that pathologists' diagnostic accuracy and confidence could be improved if they gained access to additional clinical information and in-vivo clinical and dermoscopic images of melanocytic tumors. This study examines the effect of digital training for pathologists in interpreting dermoscopic and clinical skin tumor images. The primary outcome of the upcoming DAHT RCT (Dermoscopy Augmented Histology Trial, a randomized controlled trial) is the diagnostic value (accuracy, sensitivity, and specificity) for the intervention and control group. For this purpose, we need an irrefutable gold standard diagnosis for all ...
This is a feasibility single arm study designed for obtaining early data for optimization and evaluation of the clinical potential for a new MR technique using deuterated glucose. The purpose of the study is to investigate whether this technique is useful in metabolic imaging of glioblastoma multiforme (GBM) and whether radiochemotherapy (RCT) induced changes in the brain metabolism can be detected and might be predictive for treatment response. The study will include 10 patients with histologically verified GBM scheduled for standard RCT. Patients will have MRI scan performed before and within 8 weeks after starting RCT. The scans ...
Prospective clinical trial investigating combined, dual 18F-FDG PET/CT and 64Cu-DOTATATE PET/CT imaging of patients with gastroenteropancreatic neuroendocrine neoplasms (GEP-NEN)
Early Check provides voluntary screening of newborns for a selected panel of conditions. The study has three main objectives: 1) develop and implement an approach to identify affected infants, 2) address the impact on infants and families who screen positive, and 3) evaluate the Early Check program. The Early Check screening will lead to earlier identification of newborns with rare health conditions in addition to providing important data on the implementation of this model program. Early diagnosis may result in health and development benefits for the newborns. Infants who have newborn screening in North Carolina will be eligible to...
The purpose of this study is to find out about the quality of life and health in patients who had retinoblastoma in one eye (unilateral retinoblastoma), who either received treatment with chemotherapy injected directly into an artery leading to the eye (intra-arterial chemotherapy) or removal of the eye (enucleation). By quality of life, the investigators mean how the participants are feeling about being satisfied with things in their life, including, physical health, emotional health, and their ability to carry out daily activities. The investigators want to see if either treatment option would affect quality of life differently....
In the last 10 years, the treatment of metastatic cutaneous melanoma has changed dramatically. The new systemic treatment with immunotherapy has led to a dramatic improvement in quality of life and overall survival. Systemic treatment means that the patient receives the drug as an infusion into a vein. Unfortunately, we know that immunotherapy is not equally successful in all patients. Recent studies have shown that the success of the treatment is not only influenced by the cellular composition of the metastasis, but also by its surroundings. This is called tumor microenvironment. Depending on the differences in the composition of...
The purpose of this protocol is to provide patients with adequate informed consent to understand that screening tests with minimal health risk will be performed to evaluate their eligibility for a research study. The protocol makes it clear that patients initial visit to the intramural clinical program may include screening studies that are not medically necessary for disease management, but are done purely for research purposes. Patients with a known or suspected diagnosis of cancer, HIV infection, skin disorder or immunodeficiency who are being considered for enrollment in a National Cancer Institute intramural clinical research...
