Filter by: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.
Neurosurgery for supratentorial brain tumor is frequently associated with preoperative intracranial hypertension. The evaluation of intracranial pressure is available noninvasively by measuring the diameter of the optic nerve sheath ultrasound. The evaluation of intracranial pressure by measuring the DNO in perioperative is not described in the literature. The investigators propose a pilot study to assess intracranial pressure perioperative surgery for supratentorial brain tumor. The investigators consider a diameter of the optic nerve sheath as normal and predictive of intracranial pressure below 20 mm Hg when less than 5.7 mm (on the average of two measurements on each eye). DNO the normal healthy adult unanesthetized is 5 mm. The main objective of the study is to compare the mean change in diameter of the optic nerve between the postoperative and D2 between groups of patients undergoing resection of a brain tumor and patients undergoing biopsy brain tumor. Pilot Study: Prospective, single-center, controlled, non-randomized, the number of patients is estimated according to the recruiting capabilities of neurosurgery for this type of patient in the institution, A total of 40 patients: 20 patients Tumor Resection, control group: 20 patients Biopsy Brain Tumor.
The goal of this clinical research study is to compare IMRT with IMPT in patients with glioblastoma. Researchers want to learn about cognitive side effects (mental status changes) that may occur, such as memory loss and impaired thinking. IMRT is the delivery of focused radiation therapy using photon beams and advanced computer planning to help shape the dose in order to give the highest possible dose to the tumor with the least dose to surrounding normal tissues. IMPT is also focused radiation therapy similar to IMRT, but it uses proton particles to deliver the radiation instead of photon beams. IMPT also uses advanced computer planning in order to shape the dose to the target with the least dose to surrounding normal tissues.
Patients with brain metastases who are candidates for treatment with stereotactic radiosurgery (SRS) are potential study participants. SRS delivers high-energy, precisely-focused radiation to each brain metastasis to shrink the tumor, and is the standard-of-care for patients with these tumors. Oxygen enhances the damaging effects of radiation on tumor cells. Hyperbaric oxygen (HBO) therapy increases oxygen levels in all kinds of tissues, including tumors. The purpose of this trial is to study whether it is feasible to treat patients with HBO just prior to receiving SRS, given the timing constraints of treating sequentially with HBO and then SRS. Patients will undergo HBO treatment followed by the placement of a Gill-Thomas-Cosman head frame then transported ,via stretcher, to receive SRS. The transfer and placement of the head frame needs to be completed within the 15minute time frame. The trial's secondary objectives are to determine whether it has any effects on outcomes and quality of life. As part of study participation patients will be asked to complete quality of life questionnaires as well as mini mental status questionnaires. These will be done prior to treatment and at follow up appointments throughout the next 3 years while participating in the study. Patients will be given the option to participate in the optional bio marker blood draw study which would require patients to have blood drawn at three time points, pre-treatment, the day after treatment and at their first follow up visit.
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.
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.
One of the aim of the neurosurgical treatment of brain tumor is to offer the maximal resection with the minimal neurological risk. The presurgical mapping of eloquent areas with functional magnetic resonance imaging (fMRI) is helpful to plan the surgery. BOLD fMRI is now the gold standard to map language areas. However, BOLD signal is diminished near the brain tumor. It is now possible to detect cortical activation with arterial spin labeling (ASL) techniques, detecting variations of perfusion during an activation paradigm (fASL), fASL could be interesting to detect eloquent areas near a brain tumor.
Although DIPG is not curable, re-irradiation with a modest total dose and short treatment time provides good palliation of symptoms, improves quality of life, delays disease progression and has minimal and manageable toxicity. Treatment plan: At progression, full radiological and clinical documentation necessary including a neurological exam by a neurologist will be done. Progressive patients will be referred to radiotherapy. Radiation guidelines: 30.6 Gray (Gy) will be applied in 1.8 to 2Gy fractions in conformal radiation to tumor bed. Radiation will be done in standard accelerators and according to standard guidelines used in treatment for all brain tumor patients.
The purpose of this study is to investigate whether stereotactic indigo carmine injection can safely increase the extent of tumor resection.
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.
