Previous evidence has indicated that resection for recurrent glioblastoma might benefit the prognosis of these patients in terms of overall survival. However, the demonstrated safety profile of this approach is contradictory in the literature and the specific benefits in distinct clinical and molecular patient subgroups remains ill-defined. The aim of this study, therefore, is to compare the effects of resection and best oncological treatment for recurrent glioblastoma as a whole and in clinically important subgroups. This study is an international, multicenter, prospective observational cohort study. Recurrent glioblastoma patients will undergo tumor resection or best...
There are no guidelines or prospective studies defining the optimal surgical treatment for gliomas of older patients (≥70 years) or those with limited functioning performance at presentation (KPS ≤70). Therefore, the decision between resection and biopsy is varied, amongst neurosurgeons internationally and at times even within an instiutition. This study aims to compare the effects of maximal tumor resection versus tissue biopsy on survival, functional, neurological, and quality of life outcomes in these patient subgroups. Furthermore, it evaluates which modality would maximize the potential to undergo adjuvant treatment. This study is an international, multicenter, prospective,...
Glioma patients have poor prognosis because of limited choices of treatment. Therapeutic cancer vaccines have been proved to improve survival in glioma, but resistance is a new challenge for vaccine treatment, and the mechanism is unclear. The applicant found in previous papers that glioma cells induced B7-H4 overexpression in macrophages, and the expression level of B7-H4 is highly correlated with vaccine resistance. Preliminary experiments indicated that B7-H4 protein in macrophages inhibited the expression of ATF3, STAT1 and CXCL9/10, which also resulted in decreased T cell infiltration in glioma model of mouse and was a negative factor of vaccine benefits. Therefore, the...
The investigators are interested in finding out how Prolonged Nightly Fasting (PNF) and/or health education may impact health and cancer recovery for breast cancer patients and survivors.
The trial is designed as a multicenter randomized controlled study. 246 patients with presumed Glioblastoma Multiforme in eloquent areas on diagnostic MRI will be selected by the neurosurgeons according the eligibility criteria (see under). After written informed consent is obtained, the patient will be randomized for an awake craniotomy (AC) (+/-123 patients) or craniotomy under general anesthesia (GA) (+/-123 patients), with 1:1 allocation ratio. Under GA the amount of resection of the tumour has to be performed within safe margins as judged by the surgeon during surgery. The second group will be operated with an awake craniotomy procedure where the resection boundaries for motor...
The goal of this clinical trial is to learn about the safety and effectiveness of NV-A01 in the treatment of advanced glioma patients. The main questions it aims to answer are: 1. The safety of NV-A01 in the treatment of advanced glioblastoma patients. 2. The effectiveness of NV-A01 in treating patients with advanced glioblastoma.
Prospective, single-centre study with the central question of how the metabolome from blood samples, different body fluids and tissues between patients patients with malignant melanoma in different tumour tumour stages and healthy patients and whether this is suitable for early detection of initial diagnosis, recurrence or stage shift at an early stage. The biosamples are collected in the BioBank Dresden and used for the NMR and LC-MS analyses described here. It is planned to use the biosamples for further analyses.
The aim of this study is to evaluate the efficacy and safety of the combination of thiotepa and pomalidomide in the treatment of relapsed/refractory (R/R) primary central nervous system lymphoma (PCNSL).
A greater extent of resection of the contrast-enhancing (CE) tumor part has been associated with improved outcomes in high-grade glioma patients. Recent results suggest that resection of the non-contrast-enhancing (NCE) part might yield even better survival outcomes (supramaximal resection, SMR). Therefore, this study evaluates the efficacy and safety of SMR with and without mapping techniques in HGG patients in terms of survival, functional, neurological, cognitive, and quality of life outcomes. Furthermore, it evaluates which patients benefit the most from SMR, and how they could be identified preoperatively. This study is an international, multicenter, prospective, 2-arm...
Resection of the vestibular schwannoma leads to acute peripheral or combined vestibular loss caused by a surgical lesion to the branches of the vestibular nerve and, less frequently also the lesion of the cerebellum. The lesion presents in patients with postural instability, vertigo, oscillopsia, and vegetative symptoms that may accompany it. The organism reacts to this state with the process of central compensation with the significant role of the cerebellum. The goal of the rehabilitation is to support this process and thus to make recovery faster and more efficient since not all patients are capable of complete restoration of the vestibular function. Up to date,...
