Filter by:While many studies have investigated the prognostic factors for patients undergoing surgical resection for primary brain tumors, decision-making for patients with brain metastasis (BM) is more complex because of their higher burden of comorbidities compared to those with primary brain tumors. In addition, although various prognostic indicators have been identified to predict prognosis in several types of cancer, such as the neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), prognostic nutritional index (PNI), and systemic immune-inflammation index (SII), limited studies have yet determined which group of patients would yield beater survival outcome after surgical resection for BM. This study aimed to investigate the impact of patient and perioperative characteristics and prognostic indicators on survival outcome of patients undergoing surgical resection of BM.
This clinical trial tests the effectiveness of an interactive time-restricted diet intervention (txt4fasting) in reducing neurocognitive decline and improving survival outcomes after stereotactic radiosurgery in patients with breast or lung cancer that has spread to the brain (brain metastases). Lung cancer and breast cancer are the two most frequent causes of brain metastases. The diagnosis of brain metastases is associated with poorer survival and tumor-induced and treatment-related side effects. Stereotactic radiosurgery is a type of external radiation therapy that uses special equipment to position the patient and precisely give a single large dose of radiation to a tumor. Patients who receive stereotactic radiosurgery for brain metastases may experience less neurocognitive side effects than with other types of brain radiation, but may still be at risk for their brain metastases growing, spreading, or getting worse. Patients with obesity and diabetes have been shown to have worse survival and increased radiation-related side effects. Evidence demonstrates that simply changing meal timing can have a positive impact on multiple health outcomes. Time-restricted eating, or prolonged nighttime fasting, has been proven to have positive effects on heart disease risk reduction, weight control management and chemotherapy side effect reduction. Txt4fasting may be effective in decreasing neurocognitive decline and improving survival outcomes in patients undergoing stereotactic radiosurgery for brain metastases from breast or lung cancer.
Primary and secondary brain tumors, the leading cause of death from cancer before the age of 35, represent a complex and heterogeneous group of pathologies with a generally poor prognosis. Knowledge of these tumors has made enormous strides thanks to access to biological samples, leading to a much more robust, reliable and precise histo-pronostic classification, but also, increasingly, to the identification of theranostic targets. Despite these advances, there is a real need to refine diagnostic and prognostic classification, identify the biological mechanisms involved in the formation and progression of these pathologies, develop new targeted strategies, and devise minimally invasive follow-up methods (liquid biopsies). In addition, certain non-tumoral brain lesions (e.g. malformations) can be similarly classified according to their molecular and mutational profile. This project aims to make a decisive contribution to these objectives.
The purpose of this clinical study should be that, in the context of planned resections of glial brain tumors, pieces of tissue (biopsies) are removed from the tumor at several specific locations before the actual tumor resection takes place. The aim of these biopsies in advance to the actual tumor resection will be to receive tumor tissue samples not altered in such a way that it is no longer adequate for further treatment. If not adequate, a so-called "undergrading" could occur, which means that the biological structure of the tumor is misjudged and further therapy does not achieve the desired effect in the patient. On the one hand, certain tumor regions can drift due to a "brain shift" which leads to inaccurate tissue removal, and on the other hand samples are not altered by pressure or bleeding. To carry out these biopsies, a robot positioning device (AutoGuide®) will be used that has already been approved and tested for this type of intervention. The use of the AutoGuide® is intended to ensure that the tumor sample is taken with the greatest possible precision.
Technologies 3D are demonstrating enormous potential for innovation in the field of surgery,introducing the concept of "treatment customization" (from planning surgery to implant design and manufacturing) on the patient's anatomy, simply by taking advantage of the patient's own common diagnostic images and the flexibility of 3D printing. In fact, this new construction technology allows the construction of the complex anatomical geometries with economy, simplicity and on scales of production unattainable by other traditional technologies.

The FeelFit study aims to assess the effectiveness of High-Intensity Interval Training (HIIT) in improving self-reported physical fitness in adult brain tumor patients during periods of stable disease, as compared to a waiting-list control group. Furthermore, several secondary and exploratory outcomes will be evaluated. The study is part of the GRIP (GuaRding quality survivorshiP) project, which aims to improve quality of life in brain tumor patients.
This is a health services intervention study aimed at understanding the impact of intensive multi-disciplinary care compared with standard care on patient-reported symptom outcomes and prognostic awareness in patients with brain metastases.
Resection of glioblastoma in or near functional brain tissue is challenging because of the proximity of important structures to the tumor site. To pursue maximal resection in a safe manner, mapping methods have been developed to test for motor and language function during the operation. Previous evidence suggests that these techniques are beneficial for maximum safe resection in newly diagnosed grade 2-4 astrocytoma, grade 2-3 oligodendroglioma, and recently, glioblastoma. However, their effects in recurrent glioblastoma are still poorly understood. The aim of this study, therefore, is to compare the effects of awake mapping and asleep mapping with no mapping in resections for recurrent glioblastoma. This study is an international, multicenter, prospective 3-arm cohort study of observational nature. Recurrent glioblastoma patients will be operated with mapping or no mapping techniques with a 1:1 ratio. Primary endpoints are: 1) proportion of patients with NIHSS (National Institute of Health Stroke Scale) deterioration at 6 weeks, 3 months, and 6 months after surgery and 2) residual tumor volume of the contrast-enhancing and non-contrast-enhancing part as assessed by a neuroradiologist on postoperative contrast MRI scans. Secondary endpoints are: 1) overall survival (OS), 2) progression-free survival (PFS), 4) health-related quality of life (HRQoL) at 6 weeks, 3 months, and 6 months after surgery, and 4) frequency and severity of Serious Adverse Events (SAEs) in each arm. Estimated total duration of the study is 5 years. Patient inclusion is 4 years, follow-up is 1 year. The study will be carried out by the centers affiliated with the European and North American Consortium and Registry for Intraoperative Mapping (ENCRAM).
This is a single arm phase 2 trial is to evaluate the efficacy of SRS plus adagrasib for the treatment of brain metastases for patients with KRAS G12C-mutated non-small cell lung cancer (NSCLC). A total of 30 patients will be enrolled on this study.
The goal of this multi-centre, prospective study is to assess the frequency of asymptomatic brain metastasis in patients with stage II or III Triple Negative or HER2 positive breast cancer. The main questions it aims to answer are: 1. What proportion of patients with stage II or III Triple Negative or HER2 positive breast cancer have asymptomatic brain metastases identified on a screening contrast-enhanced magnetic resonance imaging (or computed tomography when Magnetic resonance is not possible) of the brain? 2. How do patients feel about undergoing brain imaging to screen for asymptomatic Brain metastasis? 3. What clinical and tissue-based biomarkers are associated with asymptomatic detection of Brain metastasis? Participants will undergo a brain imaging, collect one blood sample to perform ctDNA analysis, and fill the Testing Morbidities Index (TMI) after imaging is done. Procedures must take place within one year of initial diagnosis, either prior to or after completion of (neo)-adjuvant systemic therapy.
