Filter by:This is a phase 2, Simon's 2-stage designed study with 2 cohorts of anti-PD-1/PD-L1 experienced patients with untreated brain metastases: 1) melanoma and 2) renal cell carcinoma (RCC).
This Phase II study is to determine the efficacy and safety of MR-Linac Guided Adaptive fractionated stereotactic radiotherapy (FSRT) in patients with brain metastases in non-small cell lung cancer.
Recently, natural D-glucose was suggested as a potential biodegradable contrast agent. The feasibility of using D-glucose for dynamic perfusion imaging was explored to detect malignant brain tumors based on blood brain barrier breakdown. Our study try to evaluate the feasibility of dynamic glucose enhanced(DGE) magnetic resonance imaging（MRI）in brain tumor, which based on D-glucose weighted chemical exchange saturation transfer (gluceoCEST).
This clinical trial studies the use of 7-Tesla (7T) magnetic resonance imaging (MRI) in detecting melanoma that has spread to the brain (melanoma brain metastases). The standard MRI brain imaging is done on 3T or similar MRI machine, but the 7T MRI machine has a larger magnet which has been shown to have superior resolution of the brain and of non-cancerous brain lesions. Diagnostic procedures such as 7T MRI may help find and diagnose melanoma brain metastases earlier than standard 3T MRI.
Background: Accessing brain tumor material for pathological diagnosis requires invasive procedures that carry risk to patients including brain hemorrhages and death. Liquid biopsies are emerging non-invasive alternatives to direct tumour biopsies but the abundance of circulating tumor DNA (ctDNA) is relatively low and this limits our ability to accurately make the molecular diagnosis of brain tumors. We have recently shown promising results that suggest that the analysis of blood samples can distinguish brain tumor types. We now want to couple liquid biopsies with high intensity focused ultrasound (HIFU) to enhance the release of tumor DNA into the circulation and increase the sensitivity/and specificity of liquid biopsies for brain tumors. The aim of this project is to build on our preliminary findings and investigate the the time dependent changes associated with HIFU of a tumor to see if it improves accuracy of diagnosis and specifically molecular subtyping of tumors based on peripheral blood and cerebrospinal fluid (CSF) circulating tumor derived markers following HIFU.
This is a single arm study of abemaciclib and endocrine therapy with stereotactic radiosurgery (SRS) among patients with hormone receptor (HR)+/HER2- metastatic breast cancer brain metastases.
The purpose of this study is to determine whether AGuIX (Activation and Guidance of Irradiation by X-ray) gadolinium-based nanoparticles make radiation work more effectively in the treatment of patients with brain metastases that are more difficult to control with stereotactic radiation alone.
This early phase I trial identifies the side effects of stereotactic radiosurgery before surgery in treating patients with cancer that has spread to the brain (brain metastases). Radiation may stimulate an anti-tumor immune response. Giving stereotactic radiosurgery before surgery may reduce the risk of the cancer coming back after surgery.
This work aims to evaluate neurocognitive performance, daily activity and quality of life and local control among patients with brain metastasis (MBM) ≥ 5 due to solid tumors treated with Stereotactic RadioSurgery (SRS) or Whole Brain RadioTherapy (WBRT). This multicentric randomised controlled trial will be conducted at the Fondazione IOM (Viagrande) in collaboration with REM (Viagrande), Hospital G. Martino (Messina) and Hospital Civico ARNAS (Palermo). It will involve, within 5 years starting from 15 September 2020, the enrollment of 100 patients (50 for each arm) with MBM ≥ 5, age ≥ 18 years, Karnofsky Performance Status (KPS) ≥ 70, life expectancy > 3 months, histological confirmation of primary tumor, with controlled or controllable extracranial disease, baseline Montreal Cognitive Assessment (MoCA) of 20/30, Barthel Activities of Daily Living score 90/100, to be subjected to SRS on each brain lesion by LINAC with monoisocentric technique and non-coplanar arcs (experimental arm) or to WBRT (control arm). The primary endpoints are neurocognitive performance, quality of life and autonomy in daily-life activities variations, the first one assessed by Moca Score and Hopkins Verbal Learning Test - Revised, the second one through the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 15 Palliative Care (EORTC QLQ-C15-PAL) and Brain Neoplasm (BN-20) questionnaires, the third one through the Barthel Index, respectively. The secondary endpoints are time to intracranial failure, overall survival, retreatments frequency, acute and late toxicities, KPS decrease. It will be considered significant a statistical difference of at least 29% between the two arms (statistical power of 80% with a significance level of 95%). This trial has been approved by the local ethics committee on July 7th 2020 (record 70). Several studies debate what is the predominant factor accountable for the development of neurocognitive decay among patients undergoing brain irradiation for MBM: radiotherapy, especially if extended to the entire brain, or intracranial disease progression? Answer to this question may come from current opportunity, thanks to recent technological advancement, to treat, with significant time savings, improved patient comfort and at the same time minimizing the dose to healthy brain tissue, Multiple Brain Metastasis simultaneously, otherwise attackable only by panencephalic irradiation. The pursuit of a local control rate comparable to that obtainable with WBRT remains the fundamental prerequisite for the aforementioned related assessments.
About 20 to 30% of patients treated for cancer will have brain metastases. These brain metastases are found more frequently in patients with lung cancer, breast cancer or melanoma. The prognosis of these patients is unfavorable but prolonged survival can be obtained with the local and systemic treatments currently available. Brain MRI is the gold standard for evaluating brain metastases but has limitations in therapeutic evaluation, partially offset by PET imaging of amino acid metabolism. Our work aims to compare the performance of PET-DOPA with standard MRI for the detection of brain metastases (≥ 5mm) in lung cancer, breast cancer and melanoma; and to characterize these lesions using dynamic acquisitions obtained with a digital PET camera with high spatial resolution. Having better knowledge of the metabolic characteristics of newly discovered brain metastases, the objective of subsequent studies will be to better assess the per- or post-therapeutic efficacy of radiotherapy and the various systemic therapies available (chemotherapy, targeted therapy, immunotherapy).
