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...
Background: The NCI Surgery Branch has developed experimental therapies that involve taking white blood cells from participants' tumor or from their blood, growing them in the laboratory in large numbers, and then giving the cells back to the patient. Objective: This study will allow participants to be followed for up to 15 years following treatment on an NCI Surgery Branch Gene Therapy Trial as required by the FDA. Eligibility: Participants must have been enrolled on an NCI Surgery Branch Gene Therapy Protocol Design Participants will be followed with a physical examination and blood tests for up...
The basic mechanisms underlying comprehension of spoken language are still largely unknown. Over the past decade, the study team has gained new insights to how the human brain extracts the most fundamental linguistic elements (consonants and vowels) from a complex and highly variable acoustic signal. However, the next set of questions await pertaining to the sequencing of those auditory elements and how they are integrated with other features, such as, the amplitude envelope of speech. Further investigation of the cortical representation of speech sounds can likely shed light on these fundamental questions. Previous research has ...
An open-label, single institutional phase II trial of losartan in patients with primary and metastatic brain tumors with an individual stepped-wedge, randomized, assessor-blinded, dose-finding design on three indications.
