Active clinical trials for "Supratentorial Neoplasms"

This study is a clinical trial to determine the safety of injecting G207 (a new experimental virus therapy) into a recurrent or progressive brain tumor. The safety of combining G207 with a single low dose of radiation, designed to enhance virus replication and tumor cell killing, will also be tested.

This phase I trial studies the side effects and best dose of lonafarnib when given together with temozolomide and to see how well they work in treating patients with glioblastoma multiforme that is has come back or did not respond to previous treatment with temozolomide. Lonafarnib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Giving lonafarnib together with temozolomide may kill more tumor cells.

This phase I trial tests the safety, side effects, and best dose of ex vivo expanded natural killer cells in treating patients with cancerous (malignant) tumors affecting the upper part of the brain (supratentorial) that have come back (recurrent) or that are growing, spreading, or getting worse (progressive). Natural killer (NK) cells are immune cells that recognize and get rid of abnormal cells in the body, including tumor cells and cells infected by viruses. NK cells have been shown to kill different types of cancer, including brain tumors in laboratory settings. Giving NK cells from unrelated donors who are screened for optimal cell qualities and determined to be safe and healthy may be effective in treating supratentorial malignant brain tumors in children and young adults.

The purpose of this study is to evaluate the effect of Hypertonic Saline 7.5% vs Mannitol 20% on brain bulk (using a 4 point scale), intracranial pressure (subdural catheter)and the changes on serum and urinary Na, K and Osmolarity during elective craniotomy for brain tumor resection.

The objective of this study is to demonstrate that scalp nerve blocks ("scalp freezing"), performed at the end of supratentorial brain surgery, will reduce post-operative pain, opioids side effects, and the time required for post-anaesthesia care unit (PACU)/Intensive Care Unit (ICU) and hospital discharge.

The primary goal of this study is to determine if a stem cell transplant in patients with newly diagnosed high risk CNS tumors (glioblastoma multiforme [GBM], high grade astrocytoma, pineoblastoma, rhabdoid tumor, supratentorial primitive neuroectodermal tumor [PNET]) increases overall survival.

This is a double center, multidisciplinary, prospective, randomized, double-blind, with a superiority hypothesis, trial including 100 patients scheduled for resection of a supratentorial brain tumour under general anesthesia.

There is no clear consensus among neuroanesthesiologists regarding which anesthetic regimen is optimal for craniotomy. Propofol and short-acting opioids (such as remifentanil, fentanyl, or sufentanil) are commonly used. However, use of opioids is associated with increased risk of respiratory depression and postoperative nausea and vomiting. Dexmedetomidine is a highly selective α2-adrenoreceptor agonist that has been considered as a useful and safe adjunct to anesthesia for various surgical procedures

Hemodynamic control during craniotomies can be a bit hectic specially during periods of intense noxious stimulation. For long anesthesiologists used high doses of opioids such as fentanyl and remifentanyl to provide analgesia with a good hemodynamic control during intraoperative period in patients undergoing craniotomies. However, the use of opioids was not devoid of side effects. Exploring other anesthetic plans using multiple opioid free anesthetic adjuvants that have analgesic effects given together in small doses appear to be appealing plan. This idea is the basis of our proposed study in which we compare the hemodynamic effects of using opioid free anesthesia versus opioid anesthesia in cranial surgeries.

Optional brain relaxation improves the surgeon's operating conditions and is likely to minimize the degree of retraction injury ,with the potential for providing patients with a better outcome. The choice of anesthetic drugs can affect intraoperative brain relaxation. Propofol suppresses brain metabolism, reduces cerebral blood flow, and provides satisfactory brain relaxation. Desflurane is often criticized in neurosurgery due to its cerebral vasodilation and potential to increase intracranial pressure, however, it has been found to have a little clinical significance. This study intends to compare the effects of desflurane with propofol on brain relaxation in patients with supratentorial tumors under mild hyperventilation, and to provide new clinical evidence for the use of desflurane in neurosurgical anesthesia.
