Circulating Immunes Cells, Cytokines and Brain Radiotherapy
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...

Circulating Tumor DNA Collection From Patients With High Grade Gliomas
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.

Clariance ErYs Registry
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...

Clear Me: Interception Trial to Detect and Clear Molecular Residual Disease in Patients With High-risk Melanoma
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...

Clindamycin and Triamcinolone in People With Glioblastoma to Prevent Skin-Related Side Effects of Tumor Treating Fields
The participants are being treated with Tumor Treating Fields (TTFields) for malignant glioma, and this type of treatment may cause skin-related side effects. This study will test whether using clindamycin and triamcinolone topical lotions can prevent skin-related side effects of TTFields.

Clinical Applicantion of Multi-Tracer PET/MR Imaging in Neurological Disorders/Disease
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.

Clinical Application of the J-PET Scanner Prototype
Positron emission tomography (PET), an advanced diagnostic imaging technique, exploits the annihilation of positrons (e+) to delineate pathological alterations within diseased tissues. Integral to PET scanners are detector systems that transform gamma photons into fluorescent photons, thereby gleaning insights into the energy, time, and spatial distribution of gamma photons emanating from positron-emitting radiopharmaceuticals. Conventional PET scanners, bear a significant financial burden primarily due to their reliance on LSO (lutetium oxyorthosilicate) or LYSO (lutetium yttrium oxyorthosilicate) scintillation crystals. The ...

Clinical, Laboratory, and Epidemiologic Characterization of Individuals and Families at High Risk of Melanoma
This study will investigate how genetic and environmental factors contribute to the development of melanoma, a type of skin cancer, and related conditions. Individuals >=4 weeks with a personal or family history of melanoma or atypical spitzoid/Spitz tumor may be eligible for this study. Participants will: - Fill out one or two questionnaires about their personal and family medical history. - Provide written consent for researchers to review their medical records and pathology materials related to their care and those of deceased relatives with melanomas, tumors, cancer, or other related illnesses for whom they...
