Filter by:The researchers' specific aims are to test the following hypotheses: Hypothesis 1: A tumor can be completely ablated by ILT with MRI-guidance. Hypothesis 2: The MRI-based 3D temperature map of tissue during ILT is predictive of destruction. Hypothesis 3: The 3D "thermal dose" map that is based on the tissue's temperature over time is more predictive of tissue destruction than the temperature map.
Positron emission tomography (PET) is a nuclear medicine procedure based on the measurement of positron emission from radiolabelled tracer molecules. These radiotracers allow biologic processes to be measured and whole body images to be obtained which demonstrates sites of radiotracer accumulation. The most common radiotracer in use today is 18F-fluorodeoxyglucose (18F-FDG) which is a radiolabelled sugar (glucose) molecule. Imaging with 18F-FDG PET is used to determine sites of abnormal glucose metabolism and can be used to characterize and localize many types of tumours. Cancer treatment and outcome depend largely on the accurate diagnosis and staging of disease. There is extensive data in the literature indicating the importance of FDG-PET imaging in accurately characterizing disease, as well as determining stage and sites of recurrent disease in many cancer types. For these indications, functional imaging with PET provides unique information which is not available from standard medical imaging modalities such as ultrasound, X-ray, computerized tomography (CT) or magnetic resonance imaging (MRI). The objectives of this study are to document the safety and efficacy of 18F-FDG produced by the British Columbia Cancer Agency (BCCA) at its Tri-University Meson Facility (TRIUMF) production facility and to evaluate FDG-PET as a diagnostic and decision making tool in the management of oncology patients in British Columbia. With a population base of over 4 million people, standardized cancer treatment protocols, and evidence based guidelines for FDG-PET imaging, the BCCA is positioned to make an important contribution to defining the role of PET in the Canadian health care system.
To explore the relationship between tissue factor levels, tumour progression, activation of blood coagulation and venous thromboembolism with malignant glioma
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 purpose of the study was to determine if treating a limited volume of normal tissue surrounding the tumor or tumor bed using conformal radiation therapy would achieve similar rates of disease control compared to standard radiation therapy. The study was also conducted to examine the effect of irradiation on neurological, endocrine and cognitive function.
Patients with recurrent or refractory solid tumors or brain tumors that are unresponsive to conventional therapy, or with no known effective therapy, will be treated. Experiments in the laboratory have shown the experimental drug RAD001C (RAD001, Everolimus) can prevent cells from multiplying. RAD001 is now being tested in diseases such as cancer, in which excessive cell multiplication needs to be stopped. The drug has been tested in adult cancer patients and has been well tolerated by subjects in these studies. It is experimental and, therefore, available in clinical trials.
The purpose of this study is to determine whether [18F]FHBG is suitable for use as an imaging probe in cancer or rheumatoid arthritis patients enrolled in cell or gene therapy trials. In this phase 1 study we will assess the safety and biodistribution of [18F]FHBG in patients.
This study aims at providing a quantitative evaluation of the accuracy of two different fixation systems, where one system is also evaluated with two different set-ups.
The standard treatment for children with brain tumors is surgical removal of the tumor followed by radiation to the brain and chemotherapy (medicines) given to shrink any remaining tumor or to prevent tumor from growing back. There are very few treatment options available for children whose brain tumor grows back after receiving radiation treatment. There is a greater risk of complications and side effects when the brain is repeatedly treated with external radiation. The side effects of repeat radiation treatment are dependent on the amount of the brain that is radiated. Radiation given with PRS during surgery is focused to the specific area of the brain where the tumor is located. Therefore, the area of the brain affected by the radiation is smaller. It is hoped that this targeted radiation will lessen the side effects to the normal brain that is not affected by the tumor. It is also hoped that a lower occurrence of side effects will increase the quality of life of children with brain tumors. The optimal dose of targeted radiation is not known. Therefore, increasing doses will be given to treat different patients, starting with the lowest possible dose. The amount of radiation to be given will depend on whether or not your child received prior radiation therapy and where the tumor is located. The groups of patients will first be divided into 2 groups: Group A, who are those who received radiation as part of their prior treatment, and Group B, who are those who did not receive any radiation treatment. Each group will be then divided again into 2 groups depending on the location of the tumor. In each group, if the lowest dose is well-tolerated with only minimal side effects by 3 patients, then the next higher dose will be given to the next 3 patients. The purposes of this research are: - To evaluate the potential side effects of a single high dose of x-rays using the Photon Radiosurgery System (PRS) given to a small area of the brain. - To determine the maximum dose of targeted radiation that can be safely given to brain tumors with the fewest side effects. - To see how well this treatment works for children with recurrent brain tumors and newly-diagnosed glioblastoma multiforme.
Treatment on this study combines two drugs: Thalomid™ (thalidomide) and carboplatin. Thalidomide has been available for many years and has been used to treat many different illnesses. Carboplatin is an effective medicine in killing cancer cells. Thalidomide works by blocking angiogenesis (the process of new blood vessel formation). If a tumor does not have blood vessels providing oxygen and nutrients, it will not be able to grow. This research will look at how combining the effects of thalidomide (preventing tumor growth) with the tumor killing effect of carboplatin effects the long-term outlook for patients with these tumors. This study will try to find out how well Thalomid™ and carboplatin combined with radiation therapy works in treating children newly diagnosed with brain stem glioma. This study will look at how well Thalomid ™ and carboplatin work in patients with recurrent brain stem glioma. This study will also look at any side effects of these treatments.
