Filter by:Bone metastasis is one of the most frequent end complications of the cancer. Radiation therapy is the mainstay of treatment in this disease. Single fraction radiotherapy in both single and multiple bone metastasis is widely used, but optimization of the single dose fractionation is needed. Two different regimens of radiotherapy dose fractionation will be investigated in both single and multiple bone metastasis and endpoints will include pain relief as well as toxicity and quality of life.
The goal of this clinical research study is to find the highest tolerable dose of dasatinib and Zometa (zoledronic acid) that can be given in combination for the treatment of breast cancer that has spread to the bone. The safety and effectiveness of this combination will also be studied.
The primary purposes of this study are to compare anterior and posterior surgical approach in treatment of CSM ad to compare variations in treatment and outcomes of CSM worldwide.
RATIONALE: Drugs used in chemotherapy, such as docetaxel and prednisolone, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Zoledronic acid may help relieve some of the symptoms caused by bone metastases. Radioactive substances, such as strontium chloride Sr 89, may help relieve bone pain caused by prostate cancer. Giving docetaxel together with prednisolone with or without zoledronic acid and/or strontium chloride Sr 89 may kill more tumor cells. PURPOSE: This randomized phase II trial is studying the side effects and how well giving docetaxel together with prednisolone works with or without zoledronic acid and/or strontium chloride Sr 89 in treating patients with prostate cancer metastatic to bone that has not responded to hormone therapy.
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.
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.
