BACKGROUND: To approach a ventral spinal pathology, a lateral viewing angle is often required. However, lateral approaches to the spine are usually more technically demanding and require certain amount of surgical expertise. In this report, we describe a simple and easy technique to obtain the lateral viewing angle to the ventral spinal pathology. CASE DESCRIPTION: The technique is demonstrated in a ventrally located meningioma at C2 level. Axial magnetic resonance imaging (MRI) showed a square posterior shift of the spinal cord with little lateral space, which necessitated a more lateral viewing angle than the conventional posterior approach...

OBJECTIVE Given the relatively lower radiosensitivity of sarcomas and the locally infiltrative patterns of spread, the authors sought to investigate spine stereotactic radiosurgery (SSRS) outcomes for metastatic sarcomas and to analyze patterns of failure. METHODS The records of 48 patients with 66 sarcoma spinal metastases consecutively treated with SSRS between 2002 and 2013 were reviewed. The Kaplan-Meier method was used to estimate rates of overall survival (OS) and local control (LC). Local recurrences were categorized as occurring infield (within the 95% isodose line [IDL]), marginally (between the 20% and 95% IDLs), or out of field...

Development of novel therapies for CNS tumors requires reliable assessment of response and progression. This requirement has been particularly challenging in neuro-oncology for which contrast enhancement serves as an imperfect surrogate for tumor volume and is influenced by agents that affect vascular permeability, such as antiangiogenic therapies. In addition, most tumors have a nonenhancing component that can be difficult to accurately quantify. To improve the response assessment in neuro-oncology and to standardize the criteria that are used for different CNS tumors, the Response Assessment in Neuro-Oncology (RANO) working group was established...

Patients with cancer are frequently affected by spinal metastases. Treatment is palliative, with the principle goals of pain relief, preservation of neurologic function, and improvement in quality of life. In the past decade, we have witnessed a dramatic change in the treatment paradigms due to the development of improved surgical strategies and systemic and radiation therapy. The most important change to these paradigms has been the integration of spinal stereotactic radiosurgery (SSRS), allowing delivery of tumoricidal radiation doses with sparing of nearby organs at risk...

Ependymoma is a locally aggressive tumor with metastatic potential that arises in diverse locations throughout the brain and spine in children. Tumor and treatment may result in significant morbidity. Cure remains elusive for many patients owing to diverse biology and resistance to conventional therapy. The implementation of systematic postoperative irradiation in clinical trials during the past 20 years has increased the proportion of patients achieving durable disease control with excellent results, as measured by objective functional outcome measures...

RATIONALE: Solitary eosinophilic granuloma (EG), the most benign, common form of Langerhans cell histiocytosis, has a self-limiting process and is associated with a good prognosis. Immobilization is recommended as the first treatment strategy for solitary EG, although the treatment protocols are still controversial. Radiotherapy and surgery are secondary treatment choices. Lesions of the upper cervical spine react differently to treatment because of their specific anatomical and motor features...

The use of structural autografts from the iliac crest for reconstruction of bony defects in the hand and foot was described by Wilson and Lance in 1965. However, very few series of this technique are published and long-term results are unknown. We present a single-institution series of 23 patients with a mean follow-up of 92 months. We also describe a novel modification of this technique using the anterior superior iliac spine for reconstruction of the adjacent joint. Failure rate was 13% at mean of 17.3 months...

Downregulated in renal cell carcinoma 1 (DRR1) has important roles in tumor cell growth, neuron survival and spine formation, and was recently shown to bind actin. However, the roles of nuclear DRR1 remain largely unexplored. Here, we identified an interaction between filamentous actin (F-actin) and DRR1 in the nucleus, and demonstrated that copper metabolism MURR1 domain-containing 1 (COMMD1) is another binding partner of DRR1. Accordingly, DRR1, F-actin and COMMD1 were shown to form a complex in the nucleus, and the stability of COMMD1 was enhanced in this complex...

BACKGROUND: The recurrence rate of cervical chordomas is high, and hence it is important to discern the prognostic factors for local relapse and overall survival (OS). METHODS: A retrospective review of 52 patients with cervical chordoma operated in our institution from January 1999 to March 2015 was performed. The association of clinicopathologic characteristics with local relapse-free survival (LRFS) and OS was analyzed. Univariate analysis was performed to determine whether tumor characteristics and types of therapy affected prognosis, and a multivariate Cox proportional hazard model was developed to further investigate local recurrence and mortality...
