NCT03853434
Although angiographic embolization has been introduced for preoperative management of spine metastases in 1975 and is suggested today by many authors in the management of such pathologies, it needs to be confirmed by RCT. It is a minimally invasive procedure, not free from complications. The recent meta-analyzes, due to the limited number of patients included are not exhaustive about the effectiveness of embolization in the reduction of the intraoperative bleeding, especially in the context of poor / moderate metastasis vascularization. We want to evaluate the efficacy of preoperative angiographic embolization of intermediate / poor vascularized spine metastases in reducing intraoperative blood loss during excision surgery.

Spine SBRT is considered a standard of care for the treatment of spinal metastases. Compared to conventional radiation therapy, spine SBRT delivers high doses of radiation to the affected areas to the spinal metastases. This study is interested in seeing whether an additional 'boost' of radiation, delivered to the affected area in the spine, will result in better long-term control of the tumor; help reduce pain; and reduce long-term side effects of radiation therapy.
NCT07346170
Current guidelines suggest postoperative spine Stereotactic Body Radiation Therapy (SBRT) should be delivered within 2-4 weeks after surgery. This approach is rife with logistical complications that create delays and barriers for patients accessing care. An alternative approach delivers postoperative spine SBRT soon after surgery, starting within a single hospital stay. This study will investigate the effects of short-term postoperative spine SBRT on wound complications in a safety lead-in, then will transition to a phase 2 trial investigating local tumor control.

One of the complications of having cancer in the spinal vertebrae is that it can spread and lead to compression of the spinal cord. Spinal cord compression is a serious event that needs to be treated quickly in order to prevent permanent damage to the spinal cord and nerves. * Researchers currently do not have the ability to accurately predict whether cancer of the vertebrae will cause spinal cord compression. It is possible that accurate predictions could allow doctors to treat patients even before they develop symptoms of spinal cord compression, thereby preventing some of the long-term consequences. Objectives: * To compare patients with cancer of the spinal vertebrae with and without symptoms of spinal cord compression by looking at markers in the blood and changes on novel magnetic resonance imaging (MRI) techniques that might allow researchers to predict who will experience spinal cord compression before they actually begin to have symptoms. Eligibility: * One group of healthy volunteers 18 years of age and older. * One group of patients 18 years of age and older who have cancer that has spread to the vertebrae without symptoms of spinal cord compression. * One group of patients 18 years of age and older who have cancer that has spread to the vertebrae with symptoms of spinal cord compression. Design: * Healthy volunteers: * Blood will be drawn from each volunteer for initial tests and for more specific biomarker tests. * Comprehensive MRI of the spine, followed by a special type of MRI called diffusion tensor imaging (DTI). It is believed that DTI may be even more sensitive in revealing spinal cord abnormalities than regular MRI sequences. * Patients with cancer of the vertebrae: * Researchers will obtain information such as pathology reports, laboratory results, diagnosis and treatment history, physical exam (PE) information, results of scans such as x-rays, MRI, computerized tomography (CT), and positron emission tomography (PET), and planned treatment details. * Additional blood samples will be taken for specific biomarker tests. * Questionnaire about pain, unusual sensations or numbness, bladder or bowel problems, and mobility. * Comprehensive MRI of the spine, followed by a DTI. * Patients who appear to have symptoms of spinal cord compression will be offered standard radiation treatment.

Pre-clinical evidence suggests that radiotherapy reduces tumour-associated vasculature. The investigators will conduct a single-arm prospective study to quantify the reduction in tumour vasculature post-radiotherapy
NCT02242786
Recently, diffusion-weighted (DW) MR imaging has widened its application on various oncologic applications. Especially, it is expected the DW MRI could provide valuable information about early response evaluation after treatment using rapid apparent diffusion coefficient (ADC) value change. It has demonstrated potential usefulness in response evaluation in the liver tumors after treatments such as transarterial chemoembolization (TACE) and radiation therapy (RT). Furthermore, it is a functional imaging technique that does not require a contrast agent, it can be safely used in patients with renal insufficiency or other medical contraindications for contrast agents. The optimal assessment of early response of RT could provide one of the most important information to prescribe patient and cancer specific RT dose. It might be also important in palliative RT of HCC bone metastasis which is related with painful aggressive mass formation. This study is performed to evaluate the usefulness of DW MRI in early response evaluation after RT for HCC bone metastasis.
