The NOMS approach to metastatic tumors: Integrating new technologies to improve outcomes / El enfoque de NOMS para los tumores metastásicos: integración de nuevas tecnologías para mejorar los resultados

Los paradigmas de tratamiento para pacientes con metástasis de columna vertebral han evolucionado significativamente en las últimas dos décadas. El cambio más transformador de estos paradigmas ha sido la integración de la radiocirugía estereotáctica espinal (sSRS). La sSRS permite la administración de dosis de radiación lítica con preservación de los órganos cercanos en riesgo, particularmente la médula espinal. La evidencia apoya la seguridad y la eficacia de la radiocirugía, ya que actualmente ofrece un control tumoral local duradero con bajas tasas de complicaciones, incluso para tumores que anteriormente se consideraban radiorresistentes a la radioterapia convencional de haz externo. El papel de la intervención quirúrgica sigue siendo consistente, pero se ha observado una tendencia hacia técnicas menos agresivas, a menudo mínimamente invasivas. Utilizando tecnologías modernas e instrumentación mejorada, los resultados quirúrgicos continúan mejorando con una morbilidad reducida. Además, los agentes dirigidos, como los productos biológicos y los inhibidores de puntos de control, han revolucionado la atención del cáncer al mejorar tanto el control local como la supervivencia del paciente. Estos avances han dado lugar a la necesidad de nuevas herramientas de pronóstico y a una revisión más crítica de los resultados a largo plazo. La naturaleza compleja de los esquemas de tratamiento actuales requiere un enfoque multidisciplinario que incluya cirujanos, oncólogos médicos, oncólogos radioterápicos, intervencionistas y especialistas en dolor. Esta revisión recapitula los datos actuales basados en la evidencia sobre el tratamiento de las metástasis espinales e integra estos datos en un marco de decisión, NOMS, que se basa en cuatro pilares centinela de la toma de decisiones en tumores metastásicos de la columna vertebral: estado neurológico, comportamiento oncológico del tumor, estabilidad mecánica, y carga sistémica de la enfermedad y comorbilidades médicas.(AU)

Spinal metastases are a common oncologic challenge as 20–40% of cancer patients are affected during the course of their illness and up to 20% of those will become symptomatic from spinal cord compression.1–5 The magnitude of this problem is expected to grow commensurate with the exponential rise in the use of targeted therapies which have demonstrated markedly improved survivals for virtually all malignant tumors. Additionally, the increased availability of advanced diagnostic imaging such as magnetic resonance imaging and 18-FDG PET scans will also serve to increase detection of spine metastatic disease. Despite extended survivals conveyed by biologics and checkpoint inhibitors, the treatment goals for patients with spine metastases remain palliative and focused on the preservation or restoration of neurological function and spinal stability, improved pain control and health related quality of life (HRQOL), and durable tumor control. Scoring systems such as the Tomita score6 and Tokuhashi revised score7 historically have been used to estimate survival and dictate treatment but increasingly have become obsolete due to their inability to incorporate and account for advances in all domains of cancer treatment.(AU)

The NOMS approach to metastatic tumors: Integrating new technologies to improve outcomes. / El enfoque de NOMS para los tumores metastásicos: integración de nuevas tecnologías para mejorar los resultados.

Treatment paradigms for patients with spine metastases have evolved significantly over the past two decades. The most transformative change to these paradigms has been the integration of spinal stereotactic radiosurgery (sSRS). sSRS allows for the delivery of tumoricidal radiation doses with sparing of nearby organs at risk, particularly the spinal cord. Evidence supports the safety and efficacy of radiosurgery as it currently offers durable local tumor control with low complication rates even for tumors previously considered radioresistant to conventional external beam radiation therapy. The role for surgical intervention remains consistent, but a trend has been observed toward less aggressive, often minimally invasive techniques. Using modern technologies and improved instrumentation, surgical outcomes continue to improve with reduced morbidity. Additionally, targeted agents such as biologics and checkpoint inhibitors have revolutionized cancer care by improving both local control and patient survival. These advances have brought forth a need for new prognostication tools and a more critical review of long-term outcomes. The complex nature of current treatment schemes necessitates a multidisciplinary approach including surgeons, medical oncologists, radiation oncologists, interventionalists and pain specialists. This review recapitulates the current state-of-the-art, evidence-based data on the treatment of spinal metastases and integrates these data into a decision framework, NOMS, which is based on four sentinel pillars of decision making in metastatic spine tumors: neurological status, Oocologic tumor behavior, mechanical stability and systemic disease burden and medical co-morbidities.

Surgical management of traumatic brain injury: a review of guidelines, pathophysiology, neurophysiology, outcomes, and controversies.

Traumatic brain injury (TBI) is a significant contributing factor to injury-related deaths worldwide. Despite the medical and fiscal importance of this subject, guidelines for the surgical management of closed and penetrating TBI are largely based on Level III evidence. Furthermore, the results of a large, costly trial designed to further elucidate the role of decompressive craniectomy, an important surgical intervention in patients with severe TBI and medically-refractory intracranial hypertension, have limited applicability. In this review, we summarize the existing guidelines for the surgical management of TBI, present an overview of the underlying pathophysiologic principles and neurophysiologic consequences relating to decompressive hemicraniectomy, highlight the history, relevant studies, and outcomes pertaining to decompressive craniectomy for patients with severe TBI, and discuss some of the current controversies in the surgical management of traumatic brain injury. Despite the varied outcomes seen in the literature, DC is indeed an important intervention in the management of TBI, as it is highly effective at reducing ICP and thus, an important higher-treatment strategy for patients with medically-refractory intracranial hypertension. There will continue to be unresolved controversies regarding decisions pertaining to defining an "optimal" surgical candidate, specific timing, techniques, and post-operative management of TBI patients who undergo surgery. New guidelines for the surgical management of TBI are forthcoming. Regardless, for neurosurgeons involved in the care of individuals with TBI, understanding the pathophysiologic and neurophysiologic consequences of surgical interventions, and gaining an understanding of the extant literature is imperative.

Proprietary physical therapy service in entry-level physical therapy curricula.

The purposes of this study were to 1) assess the value of including an expanded business administration unit that would include proprietary practice issues in an entry-level physical therapy curriculum and 2) organize topics by priority that could be included in such a unit. Twenty-seven physical therapists (100%) in private practice in Montana responded to the questionnaire. Ninety-three percent of the respondents stated that such an expansion would be valuable in the entry-level physical therapy curriculum. Topics of greatest priority were 1) Self-analysis of Resources, 2) Reimbursement, and 3) Contracting Services and Referral Sources. Topics of least priority were 1) City and State Tax and Licensure Requirements, 2) Computers and Computer Programs, and 3) Insurance Planning. Further research and development are needed to formulate methods and objectives for such an expansion.
