MRI is used in clinical routine for diagnosing brain tumors, but has limitations in identifying tumor grade, true tumor extension and differentiate viable tumor tissue from treatment induced changes and recurrences. Amino acid PET has demonstrated a great potential for defining true tumor volume, differentiate viable tumor tissue from postoperative changes or radiation necrosis, selection of biopsy site, non-invasive grading of gliomas and for treatment planning and therapy response assessment. By combining PET with MRI, the diagnostic accuracy can improve significantly for these patients. More research is however needed to compare the most promising amino acid PET tracers in...
This clinical research will evaluate the diagnostic potential of fluorescein as visualized through an operating microscope relative to 1) contrast enhancement on co-registered preoperative MR scans, 2) intraoperative ALA-induced PpIX fluorescence and 3) gold-standard histology obtained from biopsy sampling during the procedure. Subjects will include those people with operable brain tumor with first-time presumed pre-surgical diagnosis of high-grade glioma or low-grade glioma.
Background: - Pleuropulmonary blastoma (PPB) is a rare fast-growing lung tumor that is associated with other, rare tumor types. Most cases of PPB appear in children younger than 6 years of age. Recently, it has been shown that this condition can be inherited (e.g., mutation of the DICER1 gene). Researchers are studying both clinical and genetic aspects of this newly described condition. They are interested in collecting further medical history and genetic information on individuals and close relatives of individuals who have PPB or other rare associated tumors. Objectives: - To study individuals with a personal or a family history of...
Why the research is needed: Researchers are looking for a better way to treat melanoma that has spread or cannot be removed surgically. Melanoma is a type of skin cancer that starts in melanocytes, the cells that make the pigment that gives skin its color. In people with cancer, the body cannot control the growth of cells, which can come together to form tumors. This trial's new treatment is called BI-1607. BI-1607 is designed to work by improving the effectiveness of other targeted therapies already used for melanoma treatment; ipilimumab and pembrolizumab. BI-1607 will improve the ability of these two treatments to help the body's defense system to destroy cancer cells.
This study involves collecting paired tumor samples from intrasellar and cavernous sinus regions of 20 invasive pituitary tumor patients, preserving them at -80°C for quality multi-omics analysis. Proteomics and transcriptomics are employed to identify molecular differences, while imaging data (MRI/CT) assesses tumor morphology and invasion. In vitro experiments and mechanistic studies validate key findings, exploring how regional molecular differences affect tumor behavior. Data integration combines multi-omics and imaging features to uncover biomarkers and pathways associated with invasiveness and regional specificity, with statistical analysis ensuring significance and reliability.
This is a randomized controlled study to explore whether perioperative blood pressure management with different strategies can reduce the incidence of delirium and postoperative cognitive impairment and serious perfusion related complications (persistent hypotension, new heart arrhythmia, cardiac insufficiency, new stroke, sudden death, etc.) within 30 days after stroke in cancer patients at high risk for stroke. Patients were randomly divided into: 1) strict blood pressure management group: norepinephrine or phenylephrine maintenance intraoperative MAP≥85 mmHg, and 2) conventional blood pressure management group: intraoperative routine blood pressure management...
This is a single-site, single-arm, interventional study assessing the feasibility of the ARTCan Therapy Application (App) and whether it is an acceptable means of administering art therapy to young adult cancer survivors. The ARTCan Therapy App guides participants through a 6-week digital art therapy program. Subjects will participate in weekly art therapy prompts guided by the app and will complete weekly mental health quality of life (MHQoL) surveys during the intervention. In addition, baseline and end-of-intervention patient-reported outcome measures (PROMIS-DSF8a) and an acceptability survey will be administered. The hypothesis is that digital art therapy is feasible for young...
The purpose of this study is to evaluate the efficacy of digoxin in treating relapsed non-SHH, non-WNT medulloblastoma in pediatric and young adult patients.
In this study the investigators wish to describe the cohort of pediatric patients suffering from neuroblastoma and treated with Dinutuximab and to compare the costs and quality of life between the two French centers, the University Hospital of Strasbourg (HUS) and the Oncopole of Toulouse.
This phase III trial tests how well the addition of dinutuximab to Induction chemotherapy along with standard of care surgical resection of the primary tumor, radiation, stem cell transplantation, and immunotherapy works for treating children with newly diagnosed high-risk neuroblastoma. Dinutuximab is a monoclonal antibody that binds to a molecule called GD2, which is found on the surface of neuroblastoma cells, but is not present on many healthy or normal cells in the body. When dinutuximab binds to the neuroblastoma cells, it helps signal the immune system to kill the tumor cells. This helps the cells of the immune system kill the cancer cells, this is a type of immunotherapy....
