With the growing incidence of new cases and the increasing prevalence of patients living longer with spine metastasis, a methodological approach to the management of patients with recurrent or progressive disease is increasing in relevance and importance in clinical practice. As a result, disease management has evolved in these patients using advanced surgical and radiotherapy technologies. Five key goals in the management of patients with spine metastases include providing pain relief, controlling metastatic disease at the treated site, improving neurologic deficits, maintaining or improving functional status, and minimizing further mechanical instability. The focus of this review is on advanced reirradiation techniques, given that the majority of patients will be treated with upfront conventional radiotherapy and further treatment on progression is often limited by the cumulative tolerance of nearby organs at risk. This review will also discuss novel surgical approaches such as separation surgery, minimally invasive percutaneous instrumentation, and laser interstitial thermal therapy, which is increasingly being coupled with spine reirradiation to maximize outcomes in this patient population. Lastly, given the complexities of managing recurrent spinal disease, this review emphasizes the importance of multidisciplinary care from neurosurgery, radiation oncology, medical oncology, neuro-oncology, rehabilitation medicine, and palliative care.In the past 2 decades, a deeper understanding of the cancer molecular signature has resulted in longer longevity of cancer patients, hence a greater population, who potentially can develop metastatic disease. Spine metastases (SM) occur in up to 70% of cancer patients. Familiarizing ourselves with the key aspects of initial symptom-directed management is important to provide SM patients with the best patient-specific options. We will review key components of initial symptoms assessment such as pain, neurological symptoms, and spine stability. Radiographic evaluation of SM and its role in management will be reviewed. Nonsurgical treatment options are also presented and discussed, including percutaneous procedures, radiation, radiosurgery, and spine stereotactic body radiotherapy. The efforts of a multidisciplinary team will continue to ensure the best patient care as the landscape of cancer is constantly changing.Spine metastases are very common in cancer patients often requiring urgent assessment and the initiation of therapy. Treatment paradigms have changed exponentially over the past decade with the evolution and integration of stereotactic body radiotherapy, minimally invasive spine techniques, and systemic options including biologics and checkpoint inhibitors. These advances necessitate multidisciplinary assessments and interventions to optimize outcomes. The NOMS framework provides a mechanism for all practitioners to evaluate the 4 sentinel assessments required to make decisions in patients with spine metastases Neurologic, Oncologic, Mechanical Stability, and Systemic disease. The NOMS framework is continuously updated with the integration of newer technologies and evidence-based medicine as they become available. This paper presents the current iteration of NOMS with a focus on the role of medical and neuro-oncologists in the assessment and treatment of metastatic spine tumors.Metastatic spine disease occurs in more than 10% of all cancer patients. Advances in systemic treatment for cancer has led to improved overall survival for many types of cancer, which has increased the overall incidence of spinal metastases. The most common presenting complaint of patients with spinal metastases is pain. Pain originating from spinal metastases can be oncological, mechanical, and/or neurological in nature. Early recognition of these symptoms is helpful to guide treatment and accurately gauge patient prognosis. Unfortunately, the prevalence of degenerative back pain in the general population can complicate early clinical recognition of patients with metastatic spine disease. Therefore, back pain in any patient with a history of malignancy should prompt clinicians to perform an expedited workup for metastatic disease of the spine. Diagnostic imaging and laboratory studies are part of the initial work up. Obtaining pathology via biopsy to establish tumor histology is essential to determine the appropriate treatment.Spine tumors may arise within or surrounding the spinal cord and/or vertebral column. Spinal tumors can be benign or malignant. https://www.selleckchem.com/products/lxs-196.html Based on their epicenter, they may be classified as intradural-intramedullary, intradural-extramedullary, or extradural. Of these, extradural lesions are the most common, and are typically metastatic. Primary bone tumors of the spinal column comprise 5% of all primary skeletal tumors. The majority of primary spinal column tumors are benign, with malignant tumors comprising only 20%. Overall, spine metastases are the most common malignant spine tumor, and these usually arise from primaries such as lung, breast, and prostate cancers. The advent of improved systemic therapies leading to improved survival and the frequent use of imaging has positioned metastatic spine disease as the new epidemic in oncology. For spine tumors, establishing the correct diagnosis is heavily reliant on magnetic resonance imaging and histological confirmation. In this review, we will provide an overview of the epidemiology, radiological and histopathological features, and the natural history of key primary (benign and malignant) spinal cord and column tumors and metastatic spine tumors. Treatment principles for primary spinal cord or column tumors are aimed toward curative resection, whereas palliative resection forms the treatment principle for most metastatic tumors.The spine is a frequent location for metastatic disease. As local control of primary tumor pathology continues to improve, survival rates improve and, by extension, the opportunity for metastasis increases. Breast, lung, and prostate cancer are the leading contributors to spinal metastases. Spinal metastases can manifest as bone pain, pathologic fractures, spinal instability, nerve root compression, and, in its most severe form, spinal cord compression. The global extent of disease, the spinal burden, neurologic status, and life expectancy help to categorize patients as to their candidacy for treatment options. Efficient identification and workup of those with spinal metastases will expedite the treatment cascade and improve quality of life.
