The goal of this clinical research study is to establish the safety of simultaneous infusions of methotrexate and etoposide into the fourth ventricle of the brain or resection cavity in patients with recurrent malignant posterior fossa brain tumors. These tumors include medulloblastoma, ependymoma, atypical teratoid/rhabdoid tumor or other malignant brain tumor with recurrence or progression involving anywhere in the brain and/or spine. Patients' disease must have originated in the posterior fossa of the brain.
Study design and rationale: Neuroendocrine neoplasms (NENs ) represent a heterogeneous group of malignancies, which differ in terms of behavio r and prognosis. Most of t hem are advanced at diagnosis t herefore systemic treatment is proposed. While over the last years many advanced have been made especially in terms of molecular targeted therapies (MTA) like everolimus and sunitinib, chemotherapy i n NENs still represents a controversial question. Temozolomide has been reported to be active alone or in combination with other drugs in neuroendocrine neoplasms (NENs) from different origin. So far there is not universal agreement on the...
The goal of this clinical trial is to develop an imaging platform for intraoperative tumor margin delineation in 250 cases of tumor-suffered patients. The main questions it aims to answer are: • to develop the protocol of rapid assessment of surgical specimens without need for fixation, embedding, and cryosectioning required for conventional histopathology. Participants will provide a small piece of their surgical specimens from tumor removal surgery . If there is a comparison group: Researchers will compare normal specimens to see if we can observe the difference.
The aim of the study is to establish a multi-center, retrospective database for patients with intramedullary spinal cord metastases (ISCM) and analyse the functional outcome in surgically treated ISCM patients. The hypothesis is that the surgical treatment of selected ISCM patients does not lead to persistent morbidity and does not increase mortality, compared to patients that are treated non-operatively. Secondary objectives are to assess pre- to postoperative neurological deficits, ambulatory status, and overall survival of surgically treated ISCM patients. The investigators intend to include a control cohort of...
The aim of this study is to collect systematically and proactively data regarding the performance of Neuro-Patch, like complications and handling, under daily clinical practice when used as intended by the manufacturer
Glioblastoma (GBM) is the most malignant primary intracranial tumor with a median survival of about 18 months, and new therapies are urgently needed. Tumor vaccines has been shown to improve survival of GBM, but not all patients can benefit from vaccine treatment and biomarkers are urgently needed. Deletion of mismatch repair (MMR) protein and microsatellite instability (MSI) state are important features in the biological evolution of GBM, and may be used as markers for tumor vaccine. Therefore, this project will collect samples from GBM patients before and after vaccine treatment respectively, and evaluate the role of MMR/MSI gene...
Observational trial to assess the feasibility of monitoring patient reporting symptoms via mobile devices
Optic pathway glioma (OPG) can result in visual deterioration. Symptomatic patients often report deficits in visual acuity (VA), visual field, visual-evoked potentials (VEPs), strabismus, proptosis, disc swelling, and other visual/neurological problems. VA itself remains one of the most important outcome measures for OPG patients, with various studies showing strong ties of VA level to overall quality of life and well-being . Maintenance of favorable VA and vision outcomes is of paramount importance in the management of OPG. In terms of management of OPG, surgery and radiotherapy are used on a more limited basis because of location...
The study aims at investigating the cilium-related transcriptome in patients-derived glioblastoma stem cells and the potential impact of modulation of cilium players in vitro, in vivo and ex vivo in glioblastoma brain organoids. Moreover, drugs inhibiting cilia disassembly will be tested. Finally, the potential prognostic role of a cilium-related gene expression signature in glioblastoma will be assessed.
This is an observational, non-therapeutic study to collect clinical and molecular information of pediatric patients with childhood melanocytic lesions. PRIMARY OBJECTIVE: To perform a comprehensive molecular analysis of samples either from paraffin embedded and/or frozen tissue from patients with pediatric melanocytic lesions (including melanoma, spitzoid melanoma, congenital melanoma, melanoma arising in giant nevi). SECONDARY OBJECTIVE: To collect minimal information on patients treated with adjuvant or systemic therapies according to National Comprehensive Cancer Network (NCCN) guidelines.
