Active clinical trials for "Spinal Neoplasms"

This research study is evaluating suitability of a delayed magnetic resonance imaging (MRI) in management of spine tumors. Currently the standard of care is obtaining an MRI scan in the early postoperative period (within 72 hours after surgery). The purpose of this study is to see if delayed MRI (2 to 3 weeks after surgery) is similar in quality to the earlier MRI. In this study patients will undergo 2 MRIs after the surgery instead of one MRI. Patients will have one MRI about 3 days after the surgery and one MRI about 2-3 weeks after surgery.

The goal of this clinical research study is to learn about the safety and accuracy of using MRI as a guidance system during laser ablation surgery of tumors that have spread to the spine.

This study will develop a whole-of-body markerless tracking method for measuring the motion of the tumour and surrounding organs during radiation therapy to enable real-time image guidance. Routinely acquired patient data will be used to improve the training, testing and accuracy of a whole-of-body markerless tracking method. When the markerless tracking method is sufficiently advanced, according to the PI of each of the data collection sites, the markerless tracking method will be run in parallel to, but not intervening with, patient treatments during data acquisition.

Intra-spinal canal tumors are the general term of primary tumors from spinal cord or various tissues in the spinal canal and adjacent to the spinal cord, while the metastatic tumors are those from other sites other than spinal canal. Intra-spinal canal tumor is one of the most common diseases in neurosurgery, and surgery is the most effective treatment. Conventional open surgery is required to remove the posterior structures of the spine, which would lead to fracture of the posterior tension band, soft tissue injury, spine instability, and even spine deformity. So it is very important to protect and rebuild the posterior tension band for the stability of the spine. The team of Dr. John P. Kostuik from the Department of Orthopedics and Neurosurgery, the Johns Hopkins University, firstly introduced minimally invasive surgery for cervical and lumbar degenerative disease. However it has not been applied to the treatment of intra-spinal canal tumors. To date, the microsurgery of intra-spinal tumor through the trans-Quadrant channel pathway has not been widely performed in clinical practice. The investigators performed the microsurgery of intra-spinal canal tumor through the trans-Quadrant pathway in some patients previously and succeeded in the surgical treatments. The investigators analyzed the clinical data retrospectively, including surgical incision length, the volume of bleeding during operation, post-operative drainage volume, post-operative out-of-bed time point, post-operative length of stay in hospital, and post-operative visual analog pain (VAP) score. The group of patients using microsurgical technique through trans-Quadrant channel pathway showed better outcome compared with the group of patients using conventional open surgery. This innovation of microsurgery showed fewer traumas and bleeding, more rapid recovery, better prognosis and more safety in practice. Since there are some limitations to the retrospective study, it is necessary to design a prospective randomized controlled trial of the treatment of intra-spinal canal tumors using microsurgical technique through trans-Quadrant channel pathway.

Tumors of the spine can be described as primary, meaning that the tumor originated from cells normally found in the spine, or metastatic, cells from another area of the body that have spread to the spine. Metastatic tumors are more common than primary tumors. Tumors of the spine can press against the spinal cord and interfere with information traveling down from the brain to the nerves of the spinal cord. As a result, patients with spinal tumors can suffer from loss of movement and sensation within areas of the body below the tumor. In addition, tumors of the spine are typically painful conditions. Presently, the treatment of choice for spinal tumors is radiation therapy. However, many tumors of the spine become resistant to radiation therapy. In addition, because the spinal cord is often so close to the tumor it can be damaged by the radiation. Absolute (100%) ethanol is commonly known as "alcohol". It is the same kind of alcohol found in alcoholic beverages. When pure alcohol is injected directly into a tumor it can destroy cells and blood vessels. Because of this feature, researchers would like to test the effectiveness of alcohol in treating patients with spinal tumors. Researchers believe that intratumoral ethanol injection is a treatment worth studying more closely because it is minimally invasive, has been proven to be an effective treatment for other types of metastatic tumors, can be used repeatedly, and does not interfere with other treatments such as surgery. In addition to testing the effectiveness of intratumoral ethanol injection, this study will attempt to determine the causes of pain associated with spinal tumors.

Spinal cord trauma and the consequent paraplegia are possibly among the most devastating injuries in soldiers and during spine surgery, and are significant in the medical, social and financial aspects. Limited mobility, the need for assistance in all human activities, shame, and many medical complications related directly to the neural deficits make paraplegia an important target for prevention. Our study will evaluate the efficacy of Minocycline in two different groups: Minimizing the neurological damage among trauma patients. Preventing neurological damage through operation in spinal tumors patients. 2.OBJECTIVES The primary objectives of the trial are to determine: Efficacy of administrating minocycline in minimizing the neurological damage among acute spinal cord injury patients and spinal cord tumors (primary and metastases) patients? Efficacy of administrating minocycline at changing the natural history and rehabilitation of spinal cord trauma patients. Safety of applying minocycline in spinal cord injuries patients and spinal cord tumors?

Multicenter study allowing to include the first sixty patients implanted with a custom-made corpectomy implant (UNiD 3D VBR): 30 patient implanted in cervical region and 30 patients implanted in thoracolumbar region. The main objective is to confirm feasibilty and safety of patient-specific implants for one or multi-level corpectomy and fusion. This study was approved in March 2016 allowing to include retrospectivley all patients since the first implantation in January 2015 and prospectively all patients after the approval.

A safety and feasibility study of free-run and stimulated corporal electromyography (EMG) to assess autonomic neural function during spinal and/or pelvic surgery in women and men.

Objective to construct the related early activity program for patients with lumbar intraspinal tumor after hemilaminectomy, and evaluate the postoperative limb function exercise according to the content of the program. In order to improve the self-care ability and quality of life of patients, reduce postoperative complications, shorten the average length of stay, reduce hospitalization expenses and improve patient satisfaction. Objective to evaluate the efficacy and safety of establishing early activity program after hemilaminectomy for patients with lumbar intraspinal tumors
