The research is aimed at identifying new predisposition genes for endocrine tumours. Our focus initially is on pituitary adenomas including growth hormone-secreting tumors (somatotrophinomas) and prolactin secreting tumours (prolactinomas), but we wish to extend work to other pituitary tumour cases/families. The recruitment process will be as follows. 1. We will recruit patients from our own Endocrine outpatient clinics and inpatient wards. In addition we will ask colleagues in other Endocrinology Departments (or other specialties such as Clinical Genetics,Pathology, General Medicine ) to identify potentially suitable patients with endocrine & pituitary...
Studies have shown that tumors from the same patient may respond very differently to the same therapeutic agents. This study aims to investigate the genetic basis of tumors that respond abnormally well or poorly to therapeutic agents in an effort to understand the fundamental genetic basis of this response. The present protocol seeks to retrospectively perform Exome, next-generation (DNA) sequencing and/or other molecular techniques on tumor samples to identify the genetic basis of a patient's exceptional response to chemotherapy.
The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, and therapeutic activity of GI-101/GI-101A as a single agent or in combination with pembrolizumab, lenvatinib or local radiotherapy (RT) over a range of advanced and/or metastatic solid tumors.
In this study, the invesigators look at how a new MRI technique (called amide proton transfer weighted (APTw) chemical exchange saturation transfer (CEST)) can improve treatment for brain tumors through early detection of tumor progression after radiotherapy and/or chemotherapy treatment. An issue with the current treatment for patients with a brain tumor, is the inability to detect tumor progression early. An abnormality is seen on MRI scans taken shortly after treatment with radiotherapy in about 30% of patients. This abnormality may be a sign that radiotherapy treatment has worked well and will disappear on its own after a while. However, an abnormality can also be a sign...
Radiation therapy is an integral part of the multimodal primary therapy of glioblastomas. As the overall prognosis in this tumor entity remains unfavorable, current research is focused on additional drug therapies, which are often accompanied by increases in toxicity. By using proton beams instead of photon beams, it is possible to protect large parts of the brain which are not affected by the tumor more effectively. An initial retrospective matched-pair analysis showed that this theoretical physical benefit is also clinically associated with a reduction in toxicity during therapy and in the first few months thereafter. The aim of the GRIPS study is to prospectively test this...
The purpose of this research is to learn more about how what the Apple watch measures, in terms of walking data, heart rate, breathing rate, and sleep habits, relates to how participants feel. During the course of the treatment, the symptoms participants experience change, and whether the Apple watch can detect these changes. Ultimately, this knowledge is being used to design proactive tools and signatures that can predict complications or symptom changes before they happen.
In Dutch centers performing neurosurgery on and/or treating GBM, all recurrent GBM patients are discussed in local tumor boards and this setup will be used to effectively identify possible GLOW study candidates. 160 patients that will undergo re-resection in the GLOW study will be presented with WGS results leading to added treatment options.
This study will collect medical records, scan results, and complete surveys to create a registry about people with a neurofibromatosis type 1-associated brain tumor (NF1-associated glioma). A registry is a collection of health information about individuals, and it is usually focused on a specific diagnosis or condition. This registry study will help the researchers learn more about the diagnosis, treatment, and quality of life of people with NF1-associated glioma. The researchers want to understand what happens as a result of different treatments for NF1-associated glioma and how these treatments and the disease itself affect people's lives over a period of time. Information...
This phase Ib trial tests the safety and side effects of glofitamab after pre-treatment with obinutuzumab and how well they work in treating patients with central nervous system (CNS) lymphoma. Glofitamab is a bispecific antibody that can bind to two different antigens (substances that cause the body to make a specific immune response) at the same time. Glofitamab binds to CD20 on lymphoma cells, and CD3 on T-cells (a type of white blood cell) and may interfere with the ability of cancer cells to grow and spread. Obinutuzumab is a monoclonal antibody that may interfere with the ability of cancer cells to grow and spread. A monoclonal antibody is a type of protein that can bind to...
Gliomas are the most frequent type of primary brain tumors in adults; among them glioblastoma multiforme (GBM) is the most malignant, being associated with the worst prognosis. Glutamate (Glu) is an aminoacid, responsible for essential functions in the Central Nervous System (CNS), acting both as metabolite and neurotransmitter. It is essential for regulating cellular metabolism and developmental synaptogenesis, cellular migration, differentiation and death. Recent scientific evidences have demonstrated alteration in Glu synthesis and signaling being directly involved in GBM growth and invasion
