Filter by:DC vaccine manufactured and partially matured using our standard operating procedures, developed in collaboration with the HGG Immuno Group, then administered through imiquimod treated skin will be safe and feasible in children with refractory brain tumors. This will result in anti-tumor immunity that will prolong survival of subjects treated and results will be consistent with the outcomes found for subjects treated by HGG Immuno Group investigators. Study treatment will correlate with laboratory evidence of immune activation. Correlative studies will also reveal targets in the immune system which can be exploited to improve response for patients on successor trials.
The time period from diagnosis through to the end of treatment is challenging for patients. Patients need information, assistance with decision making, and emotional and social support to help cope with their diagnosis and treatment. The first meeting with the cancer doctor is especially anxiety-provoking for patients who will learn, for the first time, their treatment options and likelihood of being cured. This anxiety causes many patients to have difficulty remembering the important pieces of information that their cancer doctor tells them during this consultation. The main goal of this study is to demonstrate the benefits of giving cancer patients an audio-recording of their first consultation with their cancer doctor. The investigators will include newly diagnosed patients from cancer centres in Winnipeg and Calgary. The types of cancer that will be included in this study are brain and neuroendocrine. Patients with these types of cancer are more likely to have confused thinking, and therefore may have the most to gain from receiving their consultation recordings. The study will include 244 patients, and those who sign consent forms to participate will be assigned by chance to either receive their treatment consultation recording or not. Patients will receive their recording immediately after their consultation, and will be able to listen to the recording at any time either alone, or with family and friends. To figure out whether the consultation recording provides patients with benefits, the investigators will administer some questionnaires to patients at 1 week after the consultation, and again at 3 and 6 months after the consultation. These questionnaires will assess the following patient outcomes: i) anxiety and depression, ii) perception of being informed about the disease and treatment, iii) satisfaction with cancer care, iv) satisfaction with the doctor, and v) the extent to which patients are satisfied with their degree of involvement in treatment decision making. The investigators hypothesize that patients who receive their consultation recording will experience more benefits than patients who do not receive their consultation recording.

The main goal of the study is to present a framework, which integrates DNA, RNA and tissue data to identify and prioritize genetic events that represent clinically relevant new therapeutic targets and prognostic biomarkers for different kinds of brain tumors. The investigators study the regulation of neoplastic cell growth by oncogenes, tumor-suppressor and other cancer related genes using modern molecular genetic methods, such as chromogenic-in-situ hybridization, comparative genomic hybridization (CGH), array-CGH, cDNA microarray etc. In these studies the investigators utilize disease-specific tissue microarrays (TMA) which the investigators have constructed since 1999. Until now up to 3000 different brain tumours have been sampled to our TMA:s. These permit high-volume simultaneous analysis of molecular targets at the DNA, mRNA and protein levels. Research group has also focused its interest on the neoplastic development of gliomas, particularly on their hereditary and environmental factors.
The high-grade malignant brain tumors, glioblastoma multiforme (GBM), comprise the majority of all primary brain tumors in adults. This group of tumors also exhibits the most aggressive behavior, resulting in median overall survival of only 9-12 months. Initial therapy consists of either surgical resection, external beam radiation, or both. All patients experience a recurrence after first-line therapy, so improvements in both first-line and salvage therapy are critical to enhancing quality-of-life and prolonging survival. It is unknown if currently used intravenous (IV) therapies even cross the blood brain barrier (BBB). We have shown in a previous phase I trial that a single Superselective Intraarterial Cerebral Infusion (SIACI) of Bevacizumab (up to 15mg/kg) is safe and effective in the treatment of recurrent GBM. Therefore, this phase I/II clinical research trial is an extension of that trial in that we seek to test the hypothesis that repeated dosing of intra-arterial Bevacizumab is safe and effective in the treatment of newly diagnosed malignant glioma. By achieving the aims of this study we will also determine if repeated intra-arterial Bevacizumab improves progression free and overall survival in newly diagnosed patients. We expect that this project will provide important information regarding the utility of repeated SIACI Bevacizumab therapy for malignant glioma, and may alter the way these drugs are delivered to our patients in the near future.
Patients undergoing a brain tumour neurosurgery with craniotomy may present rare but lifethreatening post-operative complications. There are currently no strong recommendations to help the clinician in an attempt to properly hospitalise these patients after their intervention (Neuro-ICU, ICU,surgical ward). Determining risk factors of post-operative complications could optimise resources. Therefore hospitalisation in Neuro-ICU would be mandatory in only a little number of patients.
In patients undergoing craniotomy, 0.9% normal saline is commonly administered in order to reduce cerebral edema. Excessive administration of 0.9% normal saline has been to reported to cause hyperchloremic metabolic acidosis. On the other hand, hypovolemia due to insufficient fluid replacement for perioperative loss can also result in metabolic acidosis by lactic acid accumulation. However, the guideline for perioperative fluid management has not been yet established. The investigators hypothesized that intraoperative fluid management according to SVV(Stroke Volume Variation)could reduce perioperative metabolic acidosis compared to those by CVP(Central Venous Pressure). Therefore, the study is trying to determine if intraoperative fluid administration based on SVV could reduce metabolic acidosis when compared with CVP in patients undergoing craniotomy due to brain tumor who receive 0.9% normal saline as main fluid regimen.
The goal of this clinical research study is to learn if it is safe to receive methotrexate through the fourth ventricle of the brain in patients with brain tumors. Methotrexate is designed to block cancer cells from dividing, which may slow or stop their growth and spread throughout the body. This may cause the cancer cells to die.
The Methodist Hospital Neurological Institute is conducting a clinical trial for patients suffering from Metastatic brain tumors. The objective for this study is to evaluate the safety and feasibility of a MRI-guided laser thermal therapy during a real-time MRI guidance for the treatment of brain metastasis. Patient will undergo laser therapy using the MRI scan to plan the treatment and ensure proper placement of the laser within the tumor. The tumor will then be heated by the laser and monitored by study physicians through the real-time MRI to see and control temperatures in the tissue. One in place, the thermal laser will then surgically remove the lesions. After the procedure, post treatment MR images will thenbe acquired for the determination of the effective treatment region.
Recently intraoperative motor evoked potential monitoring (MEP) is widely used to reduce neural damage during neurosurgery. As neuromuscular blockade(NMB) during MEP monitoring decreases the amplitude of MEP, partial NMB is usually maintained during general anesthesia. Continuous infusion of NMB agent is preferred than bolus infusion during MEP monitoring. There are a lot of NMB agents in clinical use. But there have been no reports about the effect of changing NMB agent on efficacy of MEP monitoring. Therefore, the investigators performed a randomized controlled trial to evaluate the effect of changing NMB agent on the variability of MEP amplitude during neurosurgery.
