Filter by:Primary central nervous system lymphoma (PCNSL) is a rare subtype of extranodal non-Hodgkins Lymphoma (NHL) with rising incidence and variable response to treatment. MRI is considered the most useful imaging modality of PCNSL, but conventional MRI has its limitations, and contrast-enhanced MRI sometimes does not clearly differentiate PCNSL from other neoplasm or non-neoplastic diseases. Positron emission tomography (PET) could have a number of potential advantages in refining and improving the management of patients with PCNSL. Because of the rare incidence of PCNSL, the value of PET has however not been well defined in this subtype of lymphomas. There are a few studies that have investigated the role for FDG-PET and amino acid PET in the primary staging/diagnosis and response assessment in PCNSL patients, but the results are inconclusive. Further studies are therefore needed. Previous studies support an integration of both MRI and PET for the routine diagnostic workup and response assessment for PCNSL, and the newly available simultaneous PET/MRI scanners may have the potential to improve imaging baseline accuracy, response assessment and add prognostic value in PCNSL. The main aim of the study is to compare the sensitivity and specificity of a combined PET/MRI examination with the clinical routine MRI examination given to these patients today. It will be investigated whether PET (18F-FDG and 18F-fluciclovine) can provide additional prognostic value at baseline and in response assessment compared to MRI and established pre-treatment prognostic scores in PCNSL, and evaluate which PET/MRI parameters that are best suited as an imaging biomarker for progression-free survival.
The primary objective of this study is to evaluate the safety, efficacy and clinical activity of Pamiparib in combination with radiation therapy (RT) and/or temozolomide (TMZ) in participants with newly diagnosed or recurrent/refractory glioblastoma.
This is a retrospective study to collect already existing data and images from patients ≥ 2 years of age who had MRI for CNS diseases with MultiHance administration at a standard 0.10 mmol/kg dose or the half dose of 0.05 mmol/kg. The MRI images of all included patients will be prospectively reviewed in a blinded read to compare the efficacy of the two doses.
This pilot research trial studies blood brain barrier differences in patients with brain tumors undergoing surgery. Studying samples of tissue and blood from patients with brain tumors in the laboratory may help doctors to understand how well drugs get into different parts of a brain tumor. This may help them to determine which types of drugs may be best for treating brain tumors.
This is a Phase 2, non-randomised, open-label, multicentric study to investigate the efficacy and safety of pembrolizumab monotherapy in 7 cohorts of patients with specific rare cancers who have unresectable locally advanced or metastatic disease, which is resistant or refractory to standard therapy, or for which standard therapy does not exist, or is not considered appropriate, and for which no other experimental treatment options are available, in order to identify subsets of patients that may benefit from treatment
This phase I trial studies the side effects and best dose of prexasertib in treating pediatric patients with solid tumors that have come back after a period of time during which the tumor could not be detected or does not respond to treatment. Checkpoint kinase 1 inhibitor LY2606368 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.
This clinical trial is the first clinical trial to study Durvalumab, a checkpoint inhibitor which stimulates the patient's own immune system to act against cancer cells in children and adolescents. This trial will assess the safety and tolerability of Durvalumab in children and adolescents and also study how Durvalumab is processed in their bodies.
This phase I trial studies the side effects and best dose of entinostat in treating pediatric patients with solid tumors that have come back or have not responded to treatment. Entinostat may block some of the enzymes needed for cell division and it may help to kill tumor cells.
This study is a single center, open-label, two-part study to assess image guided surgery of intramolecular imaging in nervous system tumors. Subjects with a diagnosis of a resectable nervous system tumor who are at risk of recurrence are included. The primary goal is to observe what tissues fluoresce in the OR, and then to identify if that tissue is cancerous/tumor or normal when the histopathology is performed.
Phase I/II, open, prospective clinical trial, historically controlled. The objective is to evaluate the safety and, as a secondary measure, the efficacy of an experimental treatment based on a cellular therapy (vaccination with autologous dendritic cells pulsed with tumor lysate) in patients affected of metastatic or relapsed sarcomas or (Central Nervous System) CNS tumors.
