Active clinical trials for "Spinal Cord Neoplasms"

The purpose of this research is to combine two complementary modes of treatment, spinal interstitial laser ablation and stereotactic spine radiosurgery (SSRS) for the treatment for spinal tumors near the spinal cord with an objective to improve tumor control, improve pain control, preserve function, and improve quality of life. We will also assess how effective these combined modes of treatment are in patients with spinal metastasis with an epidural component.

The purpose of this research study is to find out what effects (good and bad) Pembrolizumab and radiosurgery have on participants with high-grade epidural disease of the spine.

Surgical site infections (SSI) are not uncommon, especially in specific high-risk groups including spinal deformity and tumor (i.e. metastatic spine surgery) surgery. Well-recognized measures have been adopted to reduce surgical site infection, and the use of topical vancomycin powder has gained popularity in recent years. Given the lack of high-quality evidence for the use of topical vancomycin to reduce surgical site infections in open posterior spine surgery, which is currently the most common approach to spine surgery, it is crucial to study the use of vancomycin powder in reducing surgical site infections. This study is a prospective, single-blinded open label randomized controlled trial, with one arm of patients having local administration of 1g vancomycin powder which will be placed in the deep wound and subcutaneous layer prior to closure of surgical site by the orthopaedic surgeon, whereas the control arm will be without such application of vancomycin. Both arms of patients will still be undergoing the same operation procedures, as well as postoperative local wound drainage and wound care. This study will provide insights on the reduction rate in superficial and/or deep surgical site infection, and also assess the cost-effectiveness of using topical vancomycin in reducing surgical site infection between different disease groups, as well as any postoperative serum vancomycin toxicity and renal impairment. These proposed findings will provide valuable information for clinicians and institutions on future measures for surgical site infection of open posterior spine surgery.

Primary spinal cord tumors constitute 2-4% of all central nervous system neoplasms; they are classfied as extradural, intradural extramedullary (IDEM: 65%), and intramedullary The most commonly seen IDEM tumors are schwannomas, neurofibromas, and meningiomas. [1] The less frequently encountered IDEM tumors include ependymomas, lipomas, hemangiomas, metastatic deposits, paragangliomas, nerve sheath myxomas, and vascular tumors.[2] Spinal cord tumors can cause different signs and symptoms, especially as tumors grow. The tumors may affect spinal cord or the nerve roots, blood vessels or bones of spine. Signs and symptoms may include: Pain at the site of the tumor due to tumor growth Back pain, often radiating to other parts of body Feeling less sensitive to pain, heat and cold Loss of bowel or bladder function Difficulty walking, muscle weakness . MRI is the investigation of choice,however other investigation such CT or X ray are important to ensure stability of the vertebral column and the optimal management is gross total excision for symptomatic lesions.[3,4] Over the years, there has been no significant change in the clinical symptoms and pathology of IDEM tumors. However, there have been dramatic improvements in the diagnosis and treatment with the advances of radiological and surgical techniques. Despite advances in operative techniques and neuroimaging, the morbidity associated with the resection of IDEM tumors continues to be significant [5,6]. Here, we examined the surgical outcomes of 20 patients with IDEM spinal cord tumors operated in Neurosurgery department at Sohag university Hospital

Spinal hemangioma is one of the most common benign vertebral tumours. Being mostly asymptomatic, it is still associated with a pain syndrome especially if encroaches into the neural canal. This study is organised to evaluate the efficacy and safety of β-blockers drugs in adults with spinal hemangioma.

The purpose of this clinical study is to collect performance and safety data for post-market Medtronic devices indicated for cranial and/or spinal indication(s). Subjects are enrolled and followed postoperatively for up to 24 months. The Ailliance clinical study is intended to collect data congruous with routine clinical care practices.

This randomized phase II/III trial is studying vorinostat, temozolomide, or bevacizumab to see how well they work compared with each other when given together with radiation therapy followed by bevacizumab and temozolomide in treating young patients with newly diagnosed high-grade glioma. Vorinostat may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as temozolomide, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as bevacizumab, can block tumor growth in different ways. Some block the ability of tumor cells to grow and spread. Others find tumor cells and help kill them or carry tumor-killing substances to them. Radiation therapy uses high-energy x-rays to kill tumor cells. It is not yet known whether giving vorinostat is more effective then temozolomide or bevacizumab when given together with radiation therapy in treating glioma.

In spinal cord tumors requiring surgical intervention, the resection difficulty is determined by two significant factors: tumor stiffness and adhesion to surrounding tissue. The stiffness of the tumor dictates the complexity of removal, while strong adhesion presents additional challenges during the surgical procedure. This clinical trial aims to assess the clinical utility of magnetic resonance elastography (MRE), in evaluating the stiffness and adhesion of spinal cord tumors and guiding surgical planning to selecting the most appropriate surgical approach for patients with spinal cord tumors.

Vertebral body resection is a wide accepted procedure in tumor resection, deformity correction, and anterior decompression in spondylosis, ossification of posterior longitudinal ligaments, and spondylodiscitis surgery. However, reconstruction of segmental defect is still challenging to spine surgeon, especially in 3-column resection, such as total en bloc spondylectomy in tumor patients. Various graft or prosthesis for reconstruction has been reported, such as structural allograft, Harms mesh cages, expandable cages, and carbon fiber stackable cages. There are no high evidence level study examining the superiority of those different methods. Recently, 3D printed vertebral body replacement has been reported in different disease entities as well, such as tumor, Kümmell's disease in osteoporosis, and spondylosis. 3D printed implant comes with superiority in production of complex geometries and regularity of the fine surface detailed that promote bone ingrowth. Although, 3D-printed titanium vertebra could achieved bone integration in human, a systemic review showed that the subsidence noted in 31.4% of spine surgery with 3D printed implants. In spine surgery, the fixation construct is sufficiently stiff, interbody motion can be reduced, and loading sharing promotes bone fusion. On the other hand, if the reconstruction is too stiff, stress shielding at fusion site occurs. The concept of dynamic fusion, as opposed to rigid fusion, has been demonstrated by an anterior cervical interbody fusion study in porcine model, demonstrating good bone formation, less postfusion stiffness, and a trend to less subsidence. Thus, we developed a 3D printed, custom-made, biomimetic prosthesis, with non-rigid structure, which has been tested in biomechanical study and porcine model, showing good bone formation and less stiffness as well. Therefore, we proposed a prospective clinical study to investigate safety, subsidence, and fusion of this prosthesis.
