Somatic mosaicism in cancer associated genes is one potential explanation for discordance in childhood cancer that has not been fully explored to date. This pilot study will focus on twins with central nervous system (CNS) tumors who are identified through the Children's Oncology Group's Project: EveryChild (PEC) registry or volunteer.
High-risk meningiomas always require postsurgical radiation treatment. Recent evidence has shown that increased radiation therapy dose may be associated with increased intracranial control of disease. In order to better define the volume of radiation treatment, the addition of PET imaging with somatostatin receptor tracers adds additional information compared to encephalon MRI with MoC alone.The present study aims to investigate whether radiation treatment with higher doses than the standard and defined using PET imaging can be safe and at the same time effective in order to increase progression-free survival in high-risk meningiomas.
Background: Gastrointestinal neuroendocrine tumors (GI NET) are a type of cancer that affects the stomach and intestines; pheochromocytoma/paragangliomas (PPGL) are tumors that grow in or near the adrenal glands. Both of these types of tumor have high levels of a protein called somatostatin receptors (SSTR) on their surfaces. Researchers want to test a treatment that targets SSTR. Objective: To test a drug ([212Pb]VMT-alpha-NET) in people with GI NET or PPGL. The drug has 2 components: a protein to bind to SSTR and a radioactive agent to kill the cancer cells. Eligibility: Adults aged 18 years or older with GI NET or PPGL tumors that have spread and cannot be removed...
This clinical study to evaluate sonobiopsy is significant because sonobiopsy will fundamentally enhance the clinician's insight into the molecular features of an intracranial lesion to tailor treatment approaches and optimize outcomes. In addition to the standard diagnostics of anatomic imaging and surgical histology, sonobiopsy has the potential to become the third pillar for brain tumor management by radically advancing the ability to easily and regularly acquire tumor genetic and molecular signatures. This enhanced capability will have a dramatic impact on patient survival and quality of life.
The objective of this clinical investigation is to assess the safety and performance of the SonoClear Acoustic Coupling Fluid (ACF). The performance will be assessed by analysis of the contrast-to-noise ratio (CNR) and assessment of image quality by using the Surgeon Image Rating (SIR) Scale. This is a prospective, multi-centre single-arm study where the performance of SonoClear ACF relative to routinely used acoustic coupling fluid is investigated by each patient being their own control. Patients with the diagnosis of HGG and LGG at up to 10 sites will be included. Additionally, safety data are collected at 30 days and 6 months post-procedure.
The brain is protected from any toxic or inflammatory molecule by the blood-brain barrier (BBB). This physical barrier is located at the level of the blood vessel walls. Because of these barrier properties, the blood vessels are also impermeable to the passage of therapeutic molecules from the blood to the brain. The development of effective treatments against glioblastoma is thus limited due to the BBB that prevents most drugs injected in the bloodstream from getting into brain tissue where the tumour is seated. The SonoCloud-9 (SC9) is an investigational device using ultrasound technology and specially developed to open the BBB in the area of and surrounding the tumour....
Patients diagnosed with glioblastoma (GBM) are faced with limited treatment options. This pilot study will evaluate the safety and feasibility of combining an investigational drug called 5-ALA with neuronavigation-guided low-intensity focused ultrasound (LIFU) for patients who have recurrent GBM. Focused ultrasound (FUS) can be used to non-invasively destroy tumor tissue while preserving normal tissue. When FUS is combined with 5-ALA, this combinatorial approach is called sonodynamic therapy (SDT), and this investigational therapy is being tested for its ability to cause damage to GBM cells. SDT will take place prior to surgery for recurrent GBM.
Objective of the study is to determine possibilities of intraoperative sonography in detecting of various brain mass lesions, assessing extent of their resection and define indications to use ultrasound-guided needle or ultrasound wire-guided port.
Patients with brain tumours experience a loss of independence, which may occur suddenly or gradually. Communication with the patient may be rapidly impaired, due to impaired alertness, language and/or neurocognitive disorders. In addition to these clinical symptoms, there is a high level of anxiety and depression in this population due to the severity of the diagnosis, with a major impact on the patients' quality of life. In this study, we are mainly interested in the proportion of this population with communication disorders where speech therapy is important In order to better take into account anxiety, which is often difficult to verbalise due to communication problems,...
The goal of this patient registry is to describe risk factors for bad prognosis of melanoma in Spain. The main questions it aims to answer are: - To describe socioeconomical individual risk factors associated with melanoma prognosis, such as gender, residence area or socioeconomic level. - To describe potentially modifiable characteristics of health care associated with prognosis, such as waiting times, type of centre that makes the diagnosis or use of teledermatology Participants data will be gathered for analysis, without any change in the way that they are being treated.
