For non-small cell lung cancer brain metastases, stereotactic radiotherapy is gradually replacing whole brain radiotherapy as the standard treatment. When patients have multiple brain metastases or larger tumors (diameter>2cm), single session stereotactic radiotherapy (SRS) may cause significant neurological damage, so fractionated stereotactic radiotherapy (FSRT) is often used. The recent objective remission rate of FSRT is about 50%, and the 1-year intracranial control rate is about 45%, but intracranial progression remains the main factor affecting long-term survival of patients. Bevacizumab is a recombinant humanized monoclonal antibody against vascular endothelial growth...
Imaging procedures such as 1-(2-[18F]FLUOROETHYL)-L-Tryptophan PET/CT in patients with cancers may help doctors assess a patient's response to treatment and help plan the best treatment in the future. The purpose is to see if there can be a better differentiation of tumor and non-tumor tissue where the tumor tissue has a higher uptake of Tryptophan.
Functional and ultrasound-guided resection of glioblastoma: assessing the use of additional imaging during surgery to improve outcomes for patients with glioblastoma brain tumours
This study is for adult patients with advanced melanoma who are receiving immunotherapy and who are planning on having surgery for their cancer. All participants in this study will receive an experimental treatment made up of focused ultrasound ablation (FUSA), a non-invasive experimental treatment that uses ultrasound waves to heat and destroy tumor tissue, and an injection in the tumor with an experimental drug that activates the immune system called polyICLC (polyinosinic-polycytidylic acid that is stabilized with carboxymethylcellulose and polylysine). Neither the drug nor the device that are used in this study have been approved by the U.S. Food and Drug Administration (FDA).
The blood brain barrier (BBB) prevents some drugs from successfully reaching the target tumor. Focused Ultrasound (FUS) using microbubbles and neuro-navigator controlled sonication is a non-invasive method of temporarily opening up the blood brain barrier to allow a greater concentration of the drug to reach into the brain tumor. This may improve response and may also reduce system side effects in the patient. The primary purpose of this study is to evaluate the feasibility of safely opening the blood brain barrier in children with progressive diffuse midline gliomas (DMG) treated with oral etoposide using focused ultrasound with microbubbles and neuro-navigator-controlled...
This phase II trial studies how well gadolinium and ferumoxytol magnetic resonance imaging (MRI) work in diagnosing patients with abnormalities in the central nervous system. Diagnostic procedures, such as gadolinium and ferumoxytol MRI, may help find and diagnose abnormalities in the central nervous system.
The aim of this pilot study is to explore whether the knowledge and experience gained during the T-GaiD project (Treatment of Gait Disorders in Dravet Syndrome - NCT03857451) can be transferred to other populations with similar problems, i.e. motor and gait problems as a result of a genetic disorder characterized by epilepsy and developmental delay. In this pilot study, 40 people with Tuberous Sclerosis Complex and 30 people with STXBP1 will be recruited via the Antwerp University Hospital and invited for a gait analysis in the M²OCEAN movement lab. The aim of the pilot study is to evaluate the feasibility of the 3D gait analysis protocol and to determine the sensitivity of...
This is a single-arm imaging study using DOTATOC peptide, labelled with the Gallium (68Ga) tracer.
NODAGA-JR11 is a novel somatostatin receptor antagonist, while Gallium-68 DOTATATE is a typical somatostatin receptor agonist. This study is to evaluate the lesion detection ability of Gallium-68 NODAGA-JR11 for the diagnostic imaging of metastatic, well-differentiated neuroendocrine tumors using positron emission tomography / computed tomography (PET/CT). The results will be compared between antagonist Gallium-68 NODAGA-JR11 and agonist Gallium-68 DOTATATE in the same group of patients.
The study of splenomegaly, and the follow-up of splenectomized patients, is one of the causes of referral of these patients to pediatric gastroenterology and oncohematology clinics, and adult internal medicine and hematology. The study and management of splenomegaly is well described among the different medical specialties to which these patients arrive. After the application of the different algorithms and the different studies that are carried out, these splenomegaly are identified as being of hepatic, infectious, inflammatory, congestive, hematological origin and primary causes. Despite these studies of splenomegaly, approximately 10-15% of these patients still...
