Brain tumor surgery is commonly associated with different degrees of preoperative intracranial hypertension and surrounding tumor edema, elicited by tumor underlying pathophysiology. During craniotomy for brain tumor resection maintenance of hemodynamic stability and intracranial homoeostasis is of paramount importance. Disordered hemodynamics or adverse stress may activate the immune inflammation or neuroendocrine responses and lead to a surge of inflammatory mediators and stress hormones, which are implicated in secondary brain insults. Adverse physiological responses caused by intraoperative disordered hemodynamics or surgery-related damage, may lead to some secondary brain injury (such as cerebral edema or cerebral hemorrhage), aggravating damage to brain tissue and affecting the recovery from anesthesia, cognition and prognosis in patients. Prevention of secondary brain injury is a key-endpoint to improve clinical outcomes in glioma patients undergoing craniotomy. Alpha2-adrenoceptor agonists have been widely used for sedation, analgesia and anti-sympathetic actions for many years, but the definite evidence of their potential use as neuroprotectants has so far been confined to animal studies, yet the findings are inconsistent. Dexmedetomidine (DEX) has been demonstrated to be a new type a2 adrenergic receptor (a2-AR) agonist, which can selectively bind with the a1 and a2 adrenergic receptor, and playing a dual role by restraining the activity of sympathetic nervous and stimulating the vagus nerve. Dexmedetomidine (DEX) also plays an important role in in inhibiting inflammatory and neuroendocrine responses. Animal experiments showed that the right must have a dexmedetomidine neuro-protective effect. However, the brain-protective effect of dexmedetomidine in anesthesia of craniotomy resection of glioma has not been reported. Thus, the aim of this study was to explore the effect of dexmedetomidine on perioperative brain protection, as well as cerebral oxygenation and metabolic status aiming to provide a basis for clinical rational drug use in patients undergoing craniotomy resection of glioma.

Collection of ctDNA and TCR data to predict the efficacy and prognosis of brain radiotherapy in patients with brain metastases from non-small cell lung cancer (NSCLC) in a comprehensive manner

Neurosurgical operations are characterised by major fluid shift, frequent use of diuretics, and prolonged operative time. The role of fluid therapy in these patients is very critical; hypovolemia might decrease cerebral perfusion; while, fluid over-infusion might swell the brain (1-3). Thus, fluid management in these procedures complex and challenging. Evidence on the optimum protocol for intraoperative fluid management in neurosurgical patients is still lacking. Adequate intracranial volume management is considered a key factor that would overcome the tumour bulk and the surrounding vasogenic oedema facilitating surgical access . Thus, a relaxed brain is one of the targets of intraoperative fluid management during craniotomy. The slack brain would allow proper surgical retraction and consequently, reduces brain retractor ischemia. Brain relaxation scale (BRS) had shown a good correlation with intracranial pressure thus, an increasing interest was paid to BRS as a simple surrogate for intracranial pressure (4-8). Goal-directed hemodynamic therapy (GDT) in the operating room is a term used to describe the use of defined hemodynamic targets to guide intravenous fluid and inotropic therapy. Pulse pressure variation (PPV) is one of the robust dynamic indices of fluid responsiveness which is based on heart-lung interactions (9-12). GDT had been frequently investigated in the operating room in high-risk patients especially in major surgery. However, the impact of GDT on patient outcomes, especially BRS, is not well evaluated in brain surgery (12-15). In this study, we evaluated PPV-guided fluid management compared to standard fluid management in patients undergoing supratentorial mass excision. We hypothesised that in these procedures, GDT might restrict intraoperative fluid volume, improve brain relaxation, and provide stable patient hemodynamics.

30 patients with brain tumor will be included in the study between the ages of 6 and 18 who have undergone surgery. Patients included in the study will be randomly assigned to two groups. The study group will be included in the Nintendo Wii Fit Plus Balance Game exercise program under the supervision of a physiotherapist for 2 days per week for 8 weeks. The control group will be taken to the conventional exercise program under the supervision of a physiotherapist for 2 days a week, 1 hour a day. The assessments will be made before the exercise program begins and at the end of the 8th week. Patients' physical measurements were assessed by anthropometric evaluations, muscle strength measurement, pain Visual Analogue Scale, walking Observational Walking Analysis, Balanced Pediatric Functional Range Test, Timed Up and Go (TUG) and one foot standing test and Nintendo Wii Fit Plus Balance Assessment, Functional capacity 2 min. With Walking Test, fatigue with PedsQL Multidimensional Fatigue Scale, daily life activities will be evaluated with WeeFIM.

The purpose of this study is to determine the effectiveness and efficiency of Single Isocenter Multi-target Stereotactic Radiosurgery (SIMT SRS) in patients with four or more brain metastases

Tumours affecting the brain are a very heterogeneous group of diseases. Accordingly, treatment strategies vary widely depending on child's age, tumour location, its resectability and histology. As a group, however, the survival rate of childhood brain tumors has improved in recent years, resulting in an increased number of survivors returning to school and reintegrating into their communities. Survival for many of them, however, has also come with severe costs such as neurocognitive and academic difficulties. Cognitive rehabilitation strategies to address these deficits have been a major focus of recent research. Evidence is now also mounting for social competence deficits among this population which may persist into late adolescence and adulthood, thereby negatively affecting long-term survivorship. Thus, there is an urgency to identify psychosocial interventions, such as social skills programs, that can reduce the social competence deficits in childhood brain tumor survivors and, therefore, modify the course of these outcomes to ensure that survivors thrive and become productive members of society. To date, no rigorous social skills intervention trials have been undertaken to address the social difficulties of these survivors. The current proposal is the first study that aims to address this gap by evaluating the efficacy of an innovative, manualized, social skills intervention program developed for this population using a multi-centre Randomized Control Trial (RCT).

Subjects are asked to take part in a clinical research study that tests Eribulin, a new drug. Eribulin is an investigational (experimental) anti-cancer agent that has not been approved by the Food and Drug Administration (FDA) for use in patients with brain metastases. Eribulin is FDA approved for use in patients with metastatic breast cancer but the effect it may or may not have on brain metastases has not been studied.

Regulation of tissue oxygen homeostasis is critical for cell function, proliferation and survival. Evidence for this continues to accumulate along with our understanding of the complex oxygen-sensing pathways present within cells. Several pathophysiological disorders are associated with a loss in oxygen homeostasis, including heart disease, stroke, and cancer. The microenvironment of tumors in particular is very oxygen heterogeneous, with hypoxic areas which may explain our difficulty treating cancer effectively. Prostate carcinomas are known to be hypoxic. Increasing levels of hypoxia within prostatic tissue is related to increasing clinical stage, patient age and a more aggressive prostate cancer. Several researches indicated that hypoxia might also play a role in esophageal cancer. In glial brain tumors, hypoxia is correlated with more rapid tumor recurrence and the hypoxic burden in newly diagnosed glioblastomas is linked to the biological aggressiveness. In brain metastases CA-IX expression (a marker for hypoxia) is correlated to the primary non-small cell lung carcinomas. Hypoxia enhances proliferation, angiogenesis, metastasis, chemoresistance and radioresistance of hepatocellular carcinoma. The hypoxic markers HIF-1α, VEGF, CA-IX and GLUT-1 were all over expressed in colorectal cancer and its liver metastases. Based on literature, hypoxia in tumors originating or disseminated to prostate, esophagus, brain and rectum cancer will be studied in this trial.

This is a Phase 2 single-arm study to assess the efficacy of perampanel as an adjunctive anti-epileptic drug (AED) in patients with primary glioma that are presenting refractory partial onset seizure activity (defined as 3 or more seizures in a 28-day period). In this study, patients will be started on a dose of 2 mg of perampanel daily taken orally at bedtime for 2 weeks. At the start of week 3 perampanel will be titrated up in dose in 2mg increments per week up to 8mg daily, as long as it is well tolerated by the patient. The highest dose of perampanel will be 8 mg orally at bedtime. Once this is achieved, patients will remain on a maintenance dose of 8 mg for 12 more weeks. The planned treatment dose is 8mg, but the dose can be modified by the physician based on patient reported tolerability. Titration and taper periods will be determined by the physician in the case where patients do not reach the planned treatment dose of 8 mg daily. Patients will be assessed in the Brain Tumor Center Clinic every 8 weeks. Study assessments will be made at enrollment, 8 weeks, 16 weeks, and 24 weeks. Assessments will include history and physical examination (H&P) including Karnofsky Performance Status (KPS), neurological examination, evaluation of seizure history, patient-reported outcomes of QoL, and computer based neurocognitive testing. After a total of 16 weeks of therapy, perampanel will be tapered down. At Week 17, patients will begin taking 6mg of perampanel, Week 18 4mg, Week 19 2mg, and Week 20 they will no longer take perampanel. Patients will be considered off treatment at the end of week 20, once perampanel has cleared their system. Patients will then be monitored through Week 24. Patients will continue to take their original AED regimen after they stop perampanel. If seizure control is achieved during the maintenance period or if seizures occur during the tapering period, patients can be continued on perampanel per the discretion of the treating physician. In this instance, perampanel will be prescribed by the treating physician and not provided within the confines of the study. Efficacy will be assessed using a log of patient-reported seizure activity. As is standard procedure at the Preston Robert Tisch Brain Tumor Center (PRTBTC), patients will be given a log to record the number of seizures that occur. Research team members will regularly contact patients for reminders and reports from the log. Safety will be assessed with the following laboratory evaluations: complete blood count (CBC) with differential, complete metabolic panel (CMP), and toxicity assessment.
