Active clinical trials for "Meningioma"

RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. PURPOSE: Phase I trial to study the effectiveness of stereotactic radiosurgery in treating patients who have brain tumors.

Cerebral blood flow (CBF) is of paramount importance to human brain function, as the brain relies on a continuous blood supply to meet its energy needs. Blockage of a cerebral blood vessel during neurosurgery, even if transient and short-lived, may result in irreversible brain tissue damage (i.e. stroke) and loss of cortical function, if not identified quickly enough. Laser speckle contrast imaging (LSCI) has been demonstrated to provide the ability to visualize flow in vessels in real time and continuously without the need for contrast agents. In LSCI, the tissue of interest is illuminated with low power laser light at red or near infrared wavelengths and the light reflected from the tissue surface is imaged onto a camera. The resulting images are laser speckle patterns and a computer processes the images to produce speckle contrast images, which are images of the motion within the field of view (ie, blood flow). The purpose of this clinical investigation is to assess the usefulness and accuracy of LSCI compared to ICGA and/or FA during neurovascular surgery. LSCI videos will be recorded automatically intraoperatively in each patient before, during, and after ICGA and/or FA in the same surgical field of view to guarantee comparability of the methods.

This study will evaluate the local control rate as well as acute and late toxicity rates of stereotactic body radiotherapy (SBRT) for the treatment of spine metastases and benign spine tumors.

This clinical trial studies yoga therapy in treating patients with malignant brain tumors. Yoga therapy may improve the quality of life of patients with brain tumors

This is a Phase 2 peptide receptor radionuclide therapy trial of 90Y-DOTATOC in patients with somatostatin receptor positive tumors.

In PINOCCHIO-Triayl, carbon ion radiotherapy is compared to proton and advanced photon radiotherapy in patients with skull base meningiomas. There will be two treatment arms with photons, one arm with hypofractionated photon radiotherapy, and one arm with conventional fractionation. The study is designed as descriptive study on feasibility of the investigated therapies aiming at a comparison of toxicities. The study will serve as a basis for further larger randomized protocols comparing efficacy of the therapies, assuming toxicity is comparable in all four treatment arms. Primary endpoint is toxicity, secondary endpoints are overall survival, progression-free survival and quality of life.

Prevention and early detection of medical problems can greatly reduce health care costs, yet time and again, people avoid or ignore services that could help detect medical problems early enough to prevent or reduce the severity of potential problems. The investigators seek to understand whether the elicitation of symptom admission by patients can predict people's perceived risk of the medical condition and voluntary pursuit of medical information.

Meningiomas are the most common primary tumors of the central nervous system in adults. High-grade forms have a high frequency of neurofibromatosis 2 (NF2) mutations and represent 25% of meningiomas, with multiple recurrences associated with morbidity and reduced survival without medical options, including immunotherapy. The meninges play a key role in neuro-immune communication through the diversity of their immune cells and the presence of meningeal lymphatic vessels (MLV). Recent data, including from our team, shows frequent infiltration of lymphocytes and myeloid cells specific to benign meningiomas. Our hypothesis is that the immune microenvironment composed of meningeal immune cells and MLVs regulates the malignant histological progression of NF2-mutated meningiomas and their immune surveillance evasion behavior This study aims to characterize the different cellular populations of the meningioma microenvironment. We will describe the exact participation of immune and vascular cell populations in the initiation and progression of meningioma, using MRI imaging and surgical biopsies of the dura mater and meningioma in patients undergoing neurosurgery for meningioma resection.

Meningioma is the most common central nervous system tumor and craniotomy with tumor removal was associated with moderate blood loss and blood transfusion. Magnesium has hypotensive effect and probably reduce intraoperative blood loss. Whether or not magnesium sulphate can reduce intraoperative blood loss and improve postoperative cognitive function is still inconclusive. So the investigators conduct the randomized control trial to compare the effect of magnesium with placebo control in blood loss and cognitive function in meningioma patient undergoing craniotomy.

Patients undergoing elective meningeoma resection surgery will be randomly assigned to one of the following two groups. After anesthesia induction but before skull-pin insertion, one group will receive scalp nerve blocks with 0.5% ropivacaine, whereas the other group will receive scalp nerve blocks with 0.9% saline. The patients' postoperative recovery quality, which is evaluated by KPS score, peri-operative inflammatory responses, and post-operative pain degree will be evaluated and compared between the two groups.
