INTRODUCTION: Whole brain (WB) re-irradiation for breast cancer patients with progressive brain metastasis after first-course WB radiotherapy (WBRT) is controversial. In this study, we sought to investigate the association between the molecular sub-classifications and breast-specific Graded Prognostic Assessment (GPA, which includes the Karnofsky performance status, molecular subtypes, and age as its indices) and the outcomes of breast cancer patients who received WB re-irradiation. METHODS: Twenty-three breast cancer patients who received WB re-irradiation for relapsed and progressive intracranial lesions after first-course WBRT between 2004 and 2016 were retrospectively reviewed...

Due to the high ability of cadmium to cross the blood-brain barrier, cadmium (Cd) causes severe neurological damages. Hence, the purpose of this study was to investigate the possible protective effect of Mangifera indica leaf extract (MLE) against Cd-induced neurotoxicity. Rats were divided into eight groups. Group 1 served as vehicle control group, groups 2, 3 and 4 received MLE (100, 200, 300 mg /kg b.wt, respectively). Group 5 was treated with CdCl2 (5 mg/kg b.wt). Groups 6, 7 and 8 were co-treated with MLE and CdCl2 using the same doses...

The solitary fibrous tumor (SFT) was first described as a mesenchymal tumor of fibroblastic type, present in the pleura. The head and neck area is the third most common site of SFT occurrence. Numb chin syndrome (NCS) is a rare neurological symptom. The current report describes the case of a 39-year-old female patient referred to the present hospital with NCS, which was later observed to be due to a large SFT in the infratemporal fossa. Computed tomography and magnetic resonance images were taken and subsequent examination of these images revealed a space occupying mass (52×50×40 mm) in the infratemporal fossa...

BACKGROUND: The goal of microsurgical removal of a vestibular schwannoma is to completely remove the tumor, to provide long-term durable cure. In many cases, less than gross total resection (GTR) is performed to preserve neurological, and especially facial nerve function. OBJECTIVE: To analyze long-term quality of life (QoL) in a cohort of patients who received either GTR or less than GTR. METHODS: Patients operated for vestibular schwannoma less than 3...

BACKGROUND: Robotic-assisted techniques have been implemented in the surgical treatment of tumors in the pelvis, abdomen, and thorax. In pelvic tumors, robotic-assisted techniques evade the need for sizable surgical exposure, but make stimulation of the nerves of the sacral plexus very difficult. OBJECTIVE: To describe how laparoscopic robotic-assisted surgery can couple with tools such as the nerve stimulator to aid in the resection of presacral masses emanating from the neural elements and potentially improve neurological outcome by preventing inadvertent injury to involved nerves...

Blood-brain barrier (BBB) is a specialized barrier that protects the brain microenvironment from toxins and pathogens in the circulation and maintains brain homeostasis. The principal sites of the barrier are endothelial cells of the brain capillaries whose barrier function results from tight intercellular junctions and efflux transporters expressed on the plasma membrane. This function is regulated by pericytes and astrocytes that together form the neurovascular unit (NVU). Several neurological diseases such as stroke, Alzheimer's disease (AD), brain tumors are associated with an impaired BBB function...

The majority of spinal cavernous angiomas (CAs) originate from the vertebral bodies with or without epidural space extension. Solitary epidural CAs are rare. In the present study, we retrospectively reviewed the records of 12 patients who underwent microsurgery for solitary spinal epidural CAs. All patients had performed pre- and postoperative magnetic resonance imaging. The patients were 7 females and 5 males with the mean age of 52.1 years. Two tumors were located in the cervicothoracic spine, nine in the thoracic spine and one in the lumbar spine, respectively...

BACKGROUND: Acantholytic squamous cell carcinoma (ASQCC), histologically characterized by intercellular bridge loosening, is recognized as a rare variant of squamous cell carcinoma (SQCC). ASQCC may demonstrate a worse prognosis than conventional SQCC. Pulmonary ASQCC is particularly rare; its biological behavior and prognostic data have not been reported. CASE PRESENTATION: We report the clinical and autopsy findings of a 71-year-old Japanese man with pulmonary ASQCC...

The identification of more effective therapies for brain tumors has been limited in part by the lack of reliable criteria for determining response and progression. Since its introduction in 1990, the MacDonald criteria have been used in neuro-oncology clinical trials to determine response, but they fail to address issues such as pseudoprogression, pseudoresponse, and nonenhancing tumor progression that have arisen with more recent therapies. The Response Assessment in Neuro-Oncology (RANO) working group, a multidisciplinary international group consisting of neuro-oncologists, medical oncologists, neuroradiologists, neurosurgeons, radiation oncologists, and neuropsychologists, was formed to improve response assessment and clinical trial endpoints in neuro-oncology...

BACKGROUND: Stereotactic body radiotherapy (SBRT) of the spine provides superior tumor control, but vertebral compression fractures are increased and the pathophysiological process underneath is not well understood. Data on histopathological changes, particularly after salvage SBRT (sSBRT) following conventional irradiation, are scarce. OBJECTIVE: To investigate surgical specimens after sSBRT and primary SBRT (pSBRT) regarding histopathological changes. METHODS: We assessed 704 patients treated with spine SBRT 2006 to 2012...

OBJECTIVE Epidermoid and dermoid cysts may be found along the cranial base and are commonly resected via open transcranial approaches. The use of endoscopic endonasal approaches for resection of these tumors has been rarely reported. METHODS The authors retrospectively reviewed the medical records of 21 patients who underwent endoscopic endonasal surgery for epidermoid and dermoid cyst resection at the University of Pittsburgh Medical Center between January 2005 and June 2014. Surgical outcomes and variables that might affect the extent of resection and complications were analyzed...

OBJECTIVE Resection of metastatic spine tumors can improve patients' quality of life by addressing pain or neurological compromise. However, resections are often complicated by wound dehiscence, infection, instrumentation failures, and the need for reoperation. Moreover, when reoperations are needed, the most common indication is surgical site infection and wound breakdown. In turn, wound reoperations increase morbidity as well as the length and cost of hospitalization. The aim of this study was to examine perioperative risk factors associated with increased rate of wound reoperations after metastatic spine tumor resection...

We describe two cases of surgical treatment of well-circumscribed basal ganglia tumors. The choice of a neurosurgical approach to a deep tumor was based on the MR tractography data and depended on the course and dislocation extent of the corticospinal tract. MR tractography provides information on the course and dislocation or destruction extent of the corticospinal tract running in the internal capsule and brainstem and clarifies the exact location of a tumor within the basal ganglia. This information promotes the choice of an optimal approach for radical resection of well-circumscribed tumor, leading to improvement in neurological symptoms and patient's quality of life...

PURPOSE OF REVIEW: Highlight some of the recent advances in gene therapy and gene modification for optic nerve disease to promote axon regeneration, neuroprotection, and increased visual functioning. RECENT FINDINGS: Visual loss secondary to optic nerve damage occurs in numerous ophthalmologic and neurologic conditions. Damaged retinal ganglion cells (RGCs) do not regenerate once they undergo apoptosis after injury. Gene therapy has been studied to replace gene mutations in disorders affecting the optic nerve as well as to alter genes responsible for suppressing or activating pathways of optic nerve growth and regeneration...
