This research aims to establish clinical evidence for optimal treatment guidelines for adrenal diseases using real-world data. The approach involves building prospective and retrospective patient registries, which will be utilized to develop and conduct research on disease-specific protocols for adrenal disorders. The study targets patients with primary aldosteronism, pheochromocytoma, adrenal cancer, adrenal incidentalomas, and mild autonomous cortisol secretion. Registries for patients with adrenal diseases will be obtained from Seoul National University Hospital and Asan Medical Center, along with securing a common data model. The ultimate goal is to conduct research to...
The purpose of this study is to discover the potential convenience and ease of using a Magnetic Resonance Imaging (MRI) technique, named Magnetic Resonance Fingerprinting (or MRF), to achieve high-quality images within a short scan time of 5 min for viewing the entire brain. This is an advanced quantitative assessment of brain tissues. This method is being applied with IVIM MRI to be able to tell the difference between a brain with radiation necrosis and a brain with tumor recurrence. Participants will consist of individuals who have received radiation therapy in the past and were diagnosed with radiation necrosis, individuals with recurrent tumors, and healthy individuals who...
The goal of this prospective observational study is to generate new personalised 3D preclinical models of pancreatic neuroendocrine tumors. The models will be exploited for studying the mechanisms underlying disease development and progression, as well as for performing drug testing. For the development of the newly proposed models, patients' surgical specimens will be evaluated by the Pathological Unit. If the presence of pathological material in excess, not required for the routine diagnostic procedure, is confirmed, such material will be employed for the generation of the proposed personalised models.
Cell-free fetal DNA (cffDNA) is present in the maternal blood from the early first trimester of gestation and makes up 5%-20% of the total circulating cell-free DNA (cfDNA) in maternal plasma. Its presence in maternal plasma has allowed development of noninvasive prenatal diagnosis for single-gene disorders (SGD-NIPD). This can be performed from 9 weeks of amenorrhea and offers an early, safe and accurate definitive diagnosis without the miscarriage risk associated with invasive procedures. One of the major difficulties is distinguishing fetal genotype in the high background of maternal cfDNA, which leads to several technical and analytical challenges. Besides, unlike noninvasive...
Tumors of the central nervous system affect 21 people per 100,000 every year, a figure that refers to countries with advanced economies, with an increase in incidence over time. Experimental evidence suggests that cancer stem cells (CSCs) may play a key role in the malignancy of these tumors. In fact, due to the hypoxic tumor microenvironment, these cells are able to create compensatory pathways that confer stem-like, angiogenic and pro-tumoral functions. Furthermore, it has been demonstrated that brain tumor stem cells are radio- and chemo-resistant and therefore not treatable with the therapeutic protocols currently in use. To date, in fact, there are no definitive treatments for...
Introduction : The incidence of duodenal neuroendocrine tumors (DNETs) is increasing. Endoscopic resection is recommended for the management of small DNETs measuring ≤10 mm. Various endoscopic techniques have been utilized for the resection of DNETs including endoscopic mucosal resection (EMR), band ligation assisted EMR, endoscopic submucosal dissection (ESD). However, the published studies report a high rate of histologically incomplete resection even with ESD. More recently, device assisted endoscopic full thickness resection (EFTR) has emerged as a safe and effective resection modality in cases with upper and lower gastrointestinal (GI) mucosal as well as submucosal lesions....
Difluoromethylornithine (DFMO) will be used in an open label, multicenter, study as Maintenance Therapy for Molecular High Risk/Very High Risk and Relapsed/Refractory Medulloblastoma.
The goal of this study is to develop better methods of diagnosis, localization, and treatment for pheochromocytomas. These tumors, which usually arise from the adrenal glands, are often difficult to detect with current methods. Pheochromocytomas release chemicals called catecholamines, causing high blood pressure. Undetected, the tumors can lead to severe medical consequences, including stroke, heart attack and sudden death, in situations that would normally pose little or no risk, such as surgery, general anesthesia or childbirth. Patients with pheochromocytoma may be eligible for this study. Candidates will be screened with a medical history and physical examination,...
MRI is used in clinical routine for diagnosing brain tumors, but has limitations in identifying tumor grade, true tumor extension and differentiate viable tumor tissue from treatment induced changes and recurrences. Amino acid PET has demonstrated a great potential for defining true tumor volume, differentiate viable tumor tissue from postoperative changes or radiation necrosis, selection of biopsy site, non-invasive grading of gliomas and for treatment planning and therapy response assessment. By combining PET with MRI, the diagnostic accuracy can improve significantly for these patients. More research is however needed to compare the most promising amino acid PET tracers in...
This clinical research will evaluate the diagnostic potential of fluorescein as visualized through an operating microscope relative to 1) contrast enhancement on co-registered preoperative MR scans, 2) intraoperative ALA-induced PpIX fluorescence and 3) gold-standard histology obtained from biopsy sampling during the procedure. Subjects will include those people with operable brain tumor with first-time presumed pre-surgical diagnosis of high-grade glioma or low-grade glioma.
