Filter by:The primary objective of this study is to evaluate the effects of Zometa (zoledronic acid, 1 mg per week versus 4 mg every four weeks) on the circulating vascular endothelial growth factor (VEGF) levels in breast cancer patients with bone metastases. Sixty patients will be randomized into two groups.
The purpose of the study is to determine the optimal surgical approach (ventral versus dorsal) for patients with multi-level cervical spondylotic myelopathy (CSM). There are no established guidelines for the management of patients with CSM, which slowly causes spinal cord injury in afflicted patients. This study aims to test the hypothesis that ventral surgery (decompressing the spinal cord from the front of the neck) and dorsal surgery (decompressing the spinal cord from the back of the neck) might differ in their overall outcome or major complication rate.
Highly selective irradiation requires accurate target definition by high-resolution three-dimensional imaging. Co-registration of FDG-PET and high-resolution CT might be the imaging modality of choice. This choice might target radiation therapy precisely to the intra-osseous volume that is responsible for pain and to spare selectively healthy bone in the vicinity of the metastasis. This strategy could result in equal anti-pain efficacy as conventional large volume radiotherapy, but could allow bone remodeling and preservation of bone structural strength in the vicinity and could lead to reduced toxicity to neighboring organs.
RATIONALE: Studying biopsy, bone marrow, and blood samples from patients with cytopenia that did not respond to treatment may help doctors learn more about the disease and plan the best treatment. PURPOSE: This laboratory study is assessing immune function in young patients with cytopenia that did not respond to treatment.
This study is to evaluate the efficacy, safety and tolerability of vorinostat in patients with lower risk Myelodysplastic Syndrome (MDS).
Decompressive surgery to relieve symptoms of spinal cord compression due to dysfunction, such as arthritis, has proved variable in success. Past research has reported that approximately one-third of surgery patients improved, one-third remained the same and one-third worsened. Currently, there are no reliable tests that can predict the outcome following surgery. We are hoping that this study will change that. Using functional MRI (fMRI), we wish to investigate the relationship between clinical symptoms and the recovery of brain activation following surgery. One can also track the concentrations of different chemicals (metabolites) by using magnetic resonance spectroscopy (MRS). We hypothesize that the recovery of normal brain activation patterns will coincide with clinical improvement. Our objective in this study is to explore the potential role of fMRI as a tool to prognose patients with cervical myelopathy. Twenty-five patients with cervical myelopathy will be imaged using a high-powered (3 Tesla) fMRI scanner before and six months following surgery. In addition, ten healthy controls will be imaged to provide a baseline measure. Both the patient and control groups will complete questionnaires at the time of their scans. These will provide information concerning the subjective experience of the individuals throughout recovery. We will compare brain activation patterns of control and patient groups to investigate how the brain heals following decompressive surgery.
The purpose of this study is to establish the safety and effectiveness of the BRYAN(R) Cervical Disc Prosthesis in treating single-level degenerative disc disease of the cervical spine.
The objective of this trial is to evaluate the safety and effectiveness of MRgFUS in the treatment of metastatic bone tumors.
The purpose of this study is to compare the safety and efficacy of Preservon(TM) treated allograft bone dowels to traditional freeze-dried allograft bone dowels (control) for fusion of degenerated cervical intervertebral discs in the treatment of cervical radiculopathy or myelopathy. Patient follow-up will be conducted at 6 weeks, 3 months, and 6 months. At 3 months after surgery, the implanted bone dowels will be assessed for subsidence; at 6 months after surgery, the implanted bone dowels will be assessed for fusion. Patients will complete questionnaires and x-rays taken at each visit. The degree of subsidence and rate of fusion will be assessed based on the evaluation of the x-rays taken. The x-ray evaluation will be conducted by a neurosurgeon who is blinded to the type of treatment that each patient has received.
Bisphosphonates have been used extensively in the treatment and the prevention of skeletal complications associated with bone metastases in patients with breast cancer and prostate cancer. The purpose of this study is to assess the effect of zoledronic acid patients with prostate cancer or breast cancer and bone metastasis.
