Filter by:Literature has shown that hypofractionated radiotherapy regimens are efficacious in patients with complicated bone metastases and have a low potential for severe treatment-related toxicities. There is a clear need for hypofractionated schedules in the complicated bone metastases population, especially when considering the overarching aim of palliative radiotherapy and the clinical features of this patient population. As well, current research examining hypofractionated approaches in bone metastases patients with impending or pathologic fractures, neuropathic pain or accompanying soft tissue masses has been markedly scarce.
The purpose of the study is to investigate effectiveness of stereotactic body radiotherapy in patients with bone metastatic disease.
Cervical myelopathy is commonly associated with degenerative spinal disease. Dysfunction of the autonomic nervous system is also evident in many cases of cervical myelopathy. Autonomic dysfunction may result in haemodynamic instability and hypotension under anaesthesia. It is important to maintain adequate mean arterial pressure in order to perfuse the spinal cord and prevent cord ischemia. Heart rate variability, the physiological variations of the differences between heart beats, has been used to diagnose autonomic dysfunction. In patients with cervical myelopathy it may enable the anaesthetist to predict hypotension thereby allowing for early treatment and prevention of spinal cord ischemia.
Translation and validation of the BOMET-QoL-10 questionnaire in Germany and assessment of its validity and responsiveness.
The goal of this clinical research study is to learn if 1 large dose of radiation therapy is better at controlling pain from cancer that has spread to the bones than 10 smaller doses of radiation. Researchers also want to learn if 1 large dose of radiation therapy can help decrease the use of drugs to control the pain, and if it can help to control the disease.
The limaprost alfadex can improve the surgical outcomes in patients with cervical myelopathy.
This study will look at two new technologies being developed for measuring cancer in bones. One of these technologies is a substance called Sodium Fluoride (NaF). Fluoride is a normal body substance. The amount that patients will receive has been shown to be very safe. One study of over 400 patients showed no adverse reactions after receiving the recommended dosage. NaF (known as a radiotracer) is taken up into the bones under a normal process and researchers can measure the amount within patient's bones through an imaging system called a Positron Emission Tomography/Magnetic Resonance Imaging (PET/MRI). This system combines aspects of both a PET study as part of the regular standard of care and an MRI study. The belief is that the combination of these two studies will be better than either study alone.People who have enrolled in this study will receive their clinically requested PET/CT scan as part of their normal diagnostic care and will follow all the said recommendations for this study such as not being pregnant, having fasted overnight, etc. Subjects will return within 7 days for a 10 mCi NaF PET/MRI study. The patients' imaging time will be up to 120 minutes depending on the MRI sequences acquired. Imaging for the PET portion of the study will take approximately 20-30 minutes with the rest of the time devoted to MRI sequences.
The aim of this study is to evaluate effectiveness of the Philips Sonalleve MR-HIFU device for the palliation of pain in patients with bone metastases. Magnetic Resonance Imaging-guided High Intensity Focused Ultrasound (MR-HIFU) uses ultrasound to palliate pain caused by bone metastases. The main palliative mechanism of the method is due to local bone denervation, caused by the heat denaturation of the periosteum layer in the treated area. The importance of this therapy is that it offers a non-invasive, focal therapy, avoiding side-effects to surrounding normal tissue that occur with radiation therapy or the need for needle insertion as with radio-frequency(RF)ablation. The study hypothesis is that MR-HIFU will be effective in treating the pain associated with bone metastases
This is a prospective observational clinical study to characterise abnormalities of thromboelastography (TEG) parameters in patients with chemotherapy-induced thrombocytopenia. The investigators are also studying the relationship between Multiplate analysis and bleeding in these patients and the effect of platelet transfusions on thrombopoietin level and percent reticulated platelets. The investigators' hypothesis is that changes in TEG-parameters reflect the patients tendency to bleed.
More than half of the middle-aged population has radiologic evidence of cervical spondylosis (Irvine 1965) and a subset of this population develops cervical spondylotic myelopathy (CSM), a condition in which the spinal cord is impaired, either by direct mechanical compression or indirectly by arterial deprivation and/or venous stasis. In this study we aim to test the hypothesis that diffusion tensor imaging can provide prognostic information on the integrity of the spine in these patients which is unavailable from conventional MRI images
