Multicenter Study
Stereotactic Radiosurgery for Intracranial Ependymomas: An International Multicenter Study.
Stereotactic radiosurgery (SRS) is a potentially important option for intracranial ependymoma patients. ⋯ SRS provides another management option for residual or recurrent progressive intracranial ependymoma patients who have failed initial surgery and RT.

Randomized Controlled Trial
Robotic Radiosurgery for Brain Metastases Diagnosed With Either SPACE or MPRAGE Sequence (CYBER-SPACE)-A Single-Center Prospective Randomized Trial.
Stereotactic radiosurgery (SRS) of brain metastases (BM) is recommended in oligometastatic scenarios as a less toxic treatment alternative to whole-brain radiotherapy. Recent findings support SRS for patients with multiple (>3) BM. Furthermore, advances in MR imaging have facilitated the detection of very small BM, as advances in SRS technology have facilitated the highly conformal and simultaneous treatment of multiple target lesions. ⋯ The present study is the first to prospectively assess the benefit of sensitive imaging and repeated stereotactic irradiation in the treatment of patients with multiple BM. It represents a novel approach, where in a palliative setting advanced technology in treatment and diagnostics is employed to improve tumor control while also reducing toxicity and preserving quality of life.

Patients who undergo surgical resection of brain metastases are at significant risk of cavity local recurrence without additional radiation therapy. Postoperative stereotactic radiosurgery (SRS) is a method of focal treatment to the cavity to maximize local control while minimizing the risk of neurocognitive detriment associated with whole brain radiation therapy. Recently published randomized trials have demonstrated the benefit of postoperative SRS in terms of cavity tumor control and preserving neurocognition. ⋯ Preoperative SRS is an alternative paradigm wherein SRS is delivered prior to surgical resection, which may effectively address some of these potential drawbacks. The goal of this review is to examine the rationale, technique, outcomes, evidence, and future directions for the use of SRS as an adjunct to surgical resection. This can be delivered as either preoperative or postoperative SRS with potential advantages and disadvantages to both approaches that will be discussed.

Does the active maintenance of arterial blood pressure after injury affect clinical outcomes in patients with thoracic and lumbar fractures? ⋯ There is insufficient evidence to recommend for or against the use of active maintenance of arterial blood pressure after thoracolumbar spinal cord injury. Grade of Recommendation: Grade Insufficient However, in light of published data from pooled (cervical and thoracolumbar) spinal cord injury patient populations, clinicians may choose to maintain mean arterial blood pressures >85 mm Hg in an attempt to improve neurological outcomes.

Osteoporotic and neoplastic vertebral compression fractures (VCF) are common and painful, threatening quality of life and increasing risk of morbidity and mortality. Balloon kyphoplasty is a percutaneous option for treating painful cancer- and osteoporosis-related VCFs, supported by 2 randomized trials demonstrating efficacy benefits of BKP over nonsurgical care. ⋯ This large, prospective, clinical study demonstrates that kyphoplasty is a safe, effective, and durable procedure for treating patients with painful VCF due to osteoporosis or cancer.
