5 Clinical Trials for Various Conditions
The study will evaluate and refine a breast screening and diagnosis device.
This study focuses on four different lesions: pancreatic cysts, lymph nodes near the gastrointestinal tract, pancreatic masses and GIST tumors. On one hand, the results obtained during previous studies are more advanced for the assessment of the diagnostic performance of Cellvizio needle-based Confocal Laser Endomicroscopy (nCLE) system for Pancreatic cysts. Safety and technical feasibility have already been performed, and an interpretation criteria classification exists. On the other hand, results for pancreatic masses, Lymph nodes and GIST are less developed. the objectives of the study are to * Assess the diagnostic performance of the Cellvizio needle-based Confocal Laser Endomicroscopy (nCLE) system in diagnosing masses and cystic tumors of the pancreas, lymph nodes, submucosal lesions of the GI tract * Define/Validate descriptive criteria of nCLE sequences in masses and cystic tu-mors of the pancreas, lymph nodes, submucosal lesions of the GI tract
The overarching goal of the proposed research is to evaluate whether qualitative and quantitative parameters in real time contrast enhanced ultrasound (CEUS) can aid in assessing suspicious indeterminate cystic appearing breast masses and ultimately determine whether or not an ultrasound guided biopsy is necessary. The underlying hypothesis is that breast masses (given BIRADS 4) that lack enhancement on CEUS will have a benign histology obtained by ultrasound guided core biopsy and/or surgery. Then, in the future, these non-enhancing cystic lesions can be followed and do not need biopsy intervention.
The nature of cysts and solid masses in the pancreas can be difficult to diagnose. They may be benign, precancerous, or cancer. Current tests such as cytology (looking under a microscope) and tumor markers do not always give us the answer. The investigators are looking for genetic markers on biopsy specimens from the pancreas that will give us a better test for diagnosis. This study is only for diagnosing these lesions. The investigators are not treating any patients.
The purpose of this study is to find out whether measurement of body composition has a prognostic value on clinical and overall outcome in pediatric patients with cystic fibrosis.
