Prospective Exploratory Study of FAPi PET/CT With Histopathology Validation in Patients With Various...
Bladder CarcinomaCervical Carcinoma14 moreThis exploratory study investigates how an imaging technique called 68Ga-FAPi-46 PET/CT can determine where and to which degree the FAPI tracer (68Ga-FAPi-46) accumulates in normal and cancer tissues in patients with cancer. Because some cancers take up 68Ga-FAPi-46 it can be seen with PET. FAP stands for Fibroblast Activation Protein. FAP is produced by cells that surround tumors (cancer associated fibroblasts). The function of FAP is not well understood but imaging studies have shown that FAP can be detected with FAPI PET/CT. Imaging FAP with FAPI PET/CT may in the future provide additional information about various cancers.
Glutamate Excitotoxicity in Brain Metastases From Lung, Breast and Melanoma Treated With Stereotactic...
Brain MetastasesAdultBrain metastases (BM) represents a devastating clinical reality, carrying an estimated survival time of less than one year. Number of reasons, including complicated tumor biology and difficulties in modeling metastatic cancer in brain microenvironment, do hinder research on this topic. BM are indeed the most frequent neoplasm in the central nervous system (CNS) and is estimated that up to 14% of all newly diagnosed cancers will metastasize to the brain. A number of reasons, including complicated tumor biology and difficulties in modeling metastatic cancer in brain microenvironment, do hinder research on this topic. Present knowledge regarding alterations in Glutamate (Glu) homeostasis and BM is poor. This study aims at investigating Glu balance in BM patients and providing supporting evidence to the identification of new putative biomarkers to be used as potential therapeutic targets.
Metabolic Characterization of Space Occupying Lesions of the Brain
Brain TumorGlioma1 moreHigh field MR-technologies are expected to boost metabolic spectroscopic imaging (MRSI), but also CEST-MRI. This is due to the fact that increased SNR is available which can be used to increase the spatial resolution of all sequences, or reduction of measurement times. Recent findings has shown that MRSI can be used to evaluate the isocitrate dehydrogenase (IDH) status of gliomas, a brain tumor type which is most often diagnosed in humans. Patients with IDH-mutated gliomas have a much longer survival time that IDH-wildtype. In IDH-mutated gliomas the substance 2-hydroxy-glutarate (2HG) is found, whereas in IDH-wildtype gliomas it is not. The underlying trial aims to measure 2HG directly with different MRSI sequences at 3 Tesla (3T) and 7 Tesla (7T) magnetic field strength. Apart from MRSI-techniques for IDH-typing it has been shown that CEST-imaging can also be performed to determine the IDH-status of gliomas. A total of 75 patients and 50 healthy controls will be examined in this study to evaluate the most accurate method for pre-operative IDH-status determination.
Use of Non-invasive Optical Analysis in Neurosurgery
Brain TumourGlioma3 moreThe present study aims to investigate the potential application of multispectral analysis, hyperspectral imaging, and fluorescence during neuro-oncological procedures, specifically during brain tumour debulking / resection. These optics techniques are entirely non-invasive and consist in camera with a filter to be linked to the standard microsurgical and endoscopic instruments used in theatre. The research procedure consists of images acquisition and data processing, with virtually no additional invasive procedures to be performed on patients.
The MOMENTUM Study: The Multiple Outcome Evaluation of Radiation Therapy Using the MR-Linac Study...
OncologyBreast Cancer36 moreThe Multi-OutcoMe EvaluatioN of radiation Therapy Using the Unity MR-Linac Study (MOMENTUM) is a multi-institutional, international registry facilitating evidenced based implementation of the Unity MR-Linac technology and further technical development of the MR-Linac system with the ultimate purpose to improve patients' survival, local, and regional tumor control and quality of life.
Intra-Tumoral Injections of Natural Killer Cells for Recurrent Malignant Brain Tumors
Pediatric Brain TumorRecurrent Pediatric Brain Tumor1 moreThis phase I trial tests the safety, side effects, and best dose of ex vivo expanded natural killer cells in treating patients with cancerous (malignant) tumors affecting the upper part of the brain (supratentorial) that have come back (recurrent) or that are growing, spreading, or getting worse (progressive). Natural killer (NK) cells are immune cells that recognize and get rid of abnormal cells in the body, including tumor cells and cells infected by viruses. NK cells have been shown to kill different types of cancer, including brain tumors in laboratory settings. Giving NK cells from unrelated donors who are screened for optimal cell qualities and determined to be safe and healthy may be effective in treating supratentorial malignant brain tumors in children and young adults.
GD2-CAR T Cells for Pediatric Brain Tumours
Brain TumorPediatric7 moreThe purpose of this study is to test the safety and efficacy of iC9-GD2-CAR T-cells, a third generation (4.1BB-CD28) CAR T cell treatment targeting GD2 in paediatric or young adult patients affected by relapsed/refractory malignant central nervous system (CNS) tumors. In order to improve the safety of the approach, the suicide gene inducible Caspase 9 (iC9) has been included.
Pyrotinib Combined With Capecitabine in HER-2 Positive Advanced Breast Cancer and Brain Metastases...
Breast CancerThis study aims to describe the different treatment time, treatment mode and clinical outcomes of pyrotinib maleate tablets combined with capecitabine in the treatment of patients with HER-2 positive advanced breast cancer with brain metastases.
JDQ443 for KRAS G12C NSCLC Brain Metastases
Non Small Cell Lung Cancer MetastaticBrain Metastases2 moreThe goal of this phase II clinical trial is to evaluate the intracranial efficacy of JDQ443, a KRAS G12C inhibitor in patients with KRAS G12C+ NSCLC and brain metastases (cohort A: asymptomatic, untreated brain metastases, cohort B: asymptomatic, treated brain metastases). The main question it aims to answer is to evaluate the intracranial efficacy, according to RANO-BM criteria, in patients with asymptomatic and untreated brain metastases. Participants will receive JDQ443 200 mg BID until unacceptable toxicity or disease progression.
