This study is a prospective, clinical study to determine if it is safe and effective to use a cochlear implant over time in individuals undergoing removal of a vestibular schwannoma (VS), benign tumor of the hearing and balance nerve or undergoing a labyrinthectomy for treatment of Meniere's disease. Individuals undergoing these surgeries will be deaf on the surgical side after the procedure. Currently, cochlear implants are approved for use and not considered investigational in individuals with hearing loss on both sides. However, use of a cochlear implant for these patient populations (single-sided hearing loss) will be considered a new use of an approved device. Participants...
The purpose of this protocol is to create a repository of blood samples from patients diagnosed with primary and metastatic brain tumors who are being seen in the Department of Radiation Oncology at Duke Cancer Center.
Patients with malignant tumours of the cephalic pole have a poor prognosis, despite a wide range of treatments. prognosis despite a large therapeutic arsenal. Among this arsenal, radiotherapy (RT) is one of the standard treatments for these tumours. However, this treatment can cause damage to the surrounding healthy tissue, has limited efficacy in hypoxic However, this treatment can cause damage to the surrounding healthy tissue, has limited efficacy in hypoxic tissue and can promote pro-tumour inflammation. In these circumstances, hadrontherapy, which uses charged heavy particles, such as protons or carbon ions, is the preferred treatment. protons or carbon ions, seems...
Improved outcomes for high-grade gliomas (HGG) require advances in our ability to monitor changes to tumour biology using non-surgical approaches. "Liquid biopsy" is a term used to describe a technique whereby tumour DNA, which has been shed off and then circulates through the blood stream, is detected and analyzed. Our goal is to develop a new type of liquid biopsy that is suitable for primary brain tumours that uses a method that is highly sensitive and allows for ongoing analysis of these tumours.
Earlier detection of disease recurrence will enable greater treatment options and has strong potential to improve patient outcomes. This project is translational and has the potential to lead to future translational research opportunities, including interventional trials in which therapeutic escalation is offered at the early circulating tumor DNA (ctDNA) molecular residual disease (MRD) detection timepoint. Ultimately, the integration of ctDNA into the clinical workflow has the potential to enhance cancer diagnosis, treatment, surveillance, and prognosis, and guide clinical decision-making in this era of personalized precision medicine.
International, prospective, single arm, multicenter and observational Post-Market Clinical Follow-up (PMCF). The overall objective of this study is to collect preoperative, intraoperative and postoperative (at 9 weeks, 6 months, 1 year and 2 years) data on the clinical complications and functional outcomes of the study devices to demonstrate safety and performance in a real-world setting. The primary objective is to demonstrate that the use of the study devices is safe. The secondary objective is to demonstrate that the use of the study devices decreases the pain, and improves the quality of life and the daily activities of the subjects.
Clear-Me is a biomarker-driven phase II study that tests whether the combination anti- lymphocyte-activation gene-3 (LAG3)/anti-programmed cell death protein 1(PD-1) inhibition Bristol-Myers Squibb (BMS986213) is superior to anti-PD-1 inhibition in patients with detectable circulating tumor deoxyribonucleic acid (ctDNA) following definitive surgery for high risk melanoma. Patients will be allocated to either Arm A or Arm B via the process of randomization. The randomization process will be stratified according to stage (Stage 2A/2B/3A/3B/3C/3D or 4), to ensure absolute balance between stage groups. The investigators are choosing only 1 stratification factor, disease stage, as...
A prospective imaging and translational tissue study in CNS lymphoma to enable further disease characterisation and the development of potential predictive and prognostic biomarkers.
This is an prospective study to evaluate the safety and efficacy of naxitamab monotherapy or combined with chemotherapy or combined with chemotherapy and checkpoint inhibitor in the treatment of pediatric high-risk and refractory/relapsed neuroblastoma in Sun Yat-sen University Cancer Center.
The goal of this clinical trial is to learn about the application of domestic PET/MR in major brain diseases. The main questions it aims to answer are: - Overcome the bottleneck of early accurate diagnosis and treatment in major brain diseases clinical practice. - Promote the clinical application of domestic PET/MR, enhance international competitiveness. Participants will have a PET/MR scan of the brain.
