Surgery for spinal metastases remains the mainstay treatment for pain, instability, and neurological deterioration due to tumor infiltration of the spine. However, several new therapies are emerging which may improve outcomes further, and in some cases even replace the need for surgery. We now have a better understanding of which factors influence survival and quality of life after surgery, and this underpins the development and application of new treatments, and assessment of outcome.Depending on genetic subtyping of tumors, novel immunotherapies and chemotherapies may be very effective in prolonging quality of life...

BACKGROUND: (68) Ga-PSMA-PET imaging is a novel promising diagnostic tool to locate early biochemical failure after radical prostatectomy (RP) in prostate cancer (PC) patients. Exact knowledge of the relapse location may result in changes of the therapy concept aside from changes to the TNM stage. To gain data for this approach, we evaluated PC patients receiving (68) Ga-PSMA-PET imaging before salvage radiotherapy (RT). METHODS AND MATERIALS: In this study, 100 patients with biochemical failure after RP± prior RT who underwent (68) Ga-PSMA PET/CT or PET/MRI were evaluated undergoing salvage RT in our department...

Meningioma is typically considered to be a benign tumor. Malignant transformation and metastasis of meningiomas are rare. Moreover, most meningiomas are intracranial, and there are few reports on intraspinal meningiomas. This report aimed to describe the clinical features and pathological findings of a case of malignant transformation and distant metastasis of intraspinal meningioma, with a review of the literature. A 44-year-old man with a bilateral lower limb paresis was diagnosed with an intradural extramedullary tumor of the thoracic spine...

Intraoperative image-guided navigation has revolutionized neurosurgery. It undoubtedly increases the surgeon's confidence and the perception of safety. While fiducials and facial masks are currently the most widely used tools for intraoperative navigation, their use is associated with certain complications. For instance, such tools require rigid fixation of the head, which increases the risk of skull fractures and epidural hematomas, and decreases both surgical flexibility and surgeon's comfort. In addition, the use of a facial mask is at times undesirable, as it may represent an obstacle during surgeries involving the face and forehead...

OBJECTIVE Cavernous sinus hemangiomas (CSHs) are rare benign vascular tumors that arise from the dural venous sinuses lateral to the sella. Stereotactic radiosurgery (SRS) has emerged as a principal alternative to microresection for small- and medium-sized CSHs. Resection is a reasonable option for large (3-4 cm in diameter) and giant (> 4 cm in diameter) CSHs. However, management of giant CSHs remains a challenge for neurosurgeons because of the high rates of morbidity and even death that stem from uncontrollable and massive hemorrhage during surgery...

BACKGROUND: Incidental meningiomas are increasingly being diagnosed due to widespread use of brain imaging. Treatment options include surveillance, surgery and stereotactic radiosurgery, but the natural history of these tumours is not fully understood and there are no accepted management guidelines to aid clinical decision-making. The aim of this study was to assess current practice in the United Kingdom and identify areas of variation for further study. METHODS: A questionnaire was distributed to all members of the Society of British Neurosurgeons (SBNS)...

Lung cancer is one of the leading causes of cancer death in men and women and treatment outcome continues to lag behind other common cancer types. A subset of lung adenocarcinoma patients exhibit a somatic mutation in EGFR or an ALK rearrangement. In these patients, targeted TKI therapy results in higher response rates, improved PFS and reduced side effects compared with platinum-based chemotherapy. Despite initial activity of the TKIs, ultimately all patients present with disease progression after about a year on TKI therapy due to resistance development...

OBJECTIVE: Stereoencephalography (SEEG) is a procedure in which electrodes are inserted into the brain to help define the epileptogenic zone. This is performed prior to definitive epilepsy surgery in patients with drug-resistant focal epilepsy when noninvasive data are inconclusive. The main risk of the procedure is hemorrhage, which occurs in 1-2% of patients. This may result from inaccurate electrode placement or a planned electrode damaging a blood vessel that was not detected on the preoperative vascular imaging...
