Multicenter prospective study of angiogenesis polymorphism validation in HCC patients treated with sorafenib. An INNOVATE study protocol.

Introduction: Although sorafenib is the upfront standard of care for advanced hepatocellular carcinoma (HCC), molecular predictors of efficacy have not been identified yet. In the ALICE-1 study, rs2010963 of VEGF-A and VEGF-C proved to be independent predictive factors for progression-free survival (PFS) and overall survival (OS) in multivariate analysis. The ALICE-1 study results were confirmed in the ALICE-2 study, in which VEGF and VEGFR SNPs were analyzed.

Assessment of the effect of mesoglycan in the treatment of audiovestibular disorders of vascular origin.

It is a well-known fact that inner ear diseases are often caused by microcirculatory disorders, and the recent literature is oriented towards investigations into the relationship between the cardiovascular system and cochleovestibular illness with related classical symptoms: tinnitus, hearing loss, and vertigo or instability. These symptoms, and particularly the vertigo, may be the alarm signal of microcirculatory disorders of the labyrinth or vertebrobasilar circulation so as to represent a possible symptom of posterior circulation stroke. The treatment aimed at correcting the haemodynamic and metabolic imbalance, generated by the cochleovestibular microcirculatory disorders, with drugs that act on the vessel wall being very useful, both alone and in combination with other treatment protocols.

Tivantinib for second-line treatment of MET-high, advanced hepatocellular carcinoma (METIV-HCC): a final analysis of a phase 3, randomised, placebo-controlled study.

Background: Tivantinib (ARQ 197), a selective, oral MET inhibitor, improved overall survival and progression-free survival compared with placebo in a randomised phase 2 study in patients with high MET expression (MET-high) hepatocellular carcinoma previously treated with sorafenib. The aim of this phase 3 study was to confirm the results of the phase 2 trial.

Methods: We did a phase 3, randomised, double-blind, placebo-controlled study in 90 centres in Australia, the Americas, Europe, and New Zealand.

A Novel and Freely Available Interactive 3d Model of the Internal Carotid Artery.

High-resolution 3D human angiography (isometric voxel's size 0.36 mm) and Computed Tomography angiography images were exported to Virtual Reality Modeling Language (VRML) format for processing in a 3D software platform and embedding in a 3D Portable Document Format (PDF) document that can be freely downloaded at http://diposit.

Cerebrovascular disorders and Fahr's disease: Report of two cases and literature review.

Fahr's disease is a rare idiopathic nosological entity, characterized by calcification of the basal ganglia and dentate nuclei of the cerebellum. Sometimes it may be associated to other diseases like cerebrovascular disorders. However, this link remains unclear and it needs to be further validated.

Fluorescein-assisted stereotactic needle biopsy of brain tumors: a single-center experience and systematic review.

Over the last years, fluorescence-based technology has begun an emergent intraoperative method for diagnostic confirmation of brain tumor tissue in stereotactic needle biopsy. However, the actual level of evidence is quite low, especially about fluorescein sodium (FL) application. This method needs to be further validated and better analyzed about its impact in clinical practice.

Frontolateral Approach Combined with Endoscopic Endonasal Extradural Posterior Clinoidectomy to the Upper Clival Region: Anatomic and Feasibility Study.

Background: Surgical management of lesions located in the upper clival region is challenging. Complex open transcranial approaches have been used to reach surgical targets in these areas. The frontotemporozygomatic approach combined with an intradural posterior clinoidectomy has been proposed as the most reliable route to manage such lesions.

Endoscopic transorbital superior eyelid approach: anatomical study from a neurosurgical perspective.

OBJECTIVERecent studies have proposed the superior eyelid endoscopic transorbital approach as a new minimally invasive route to access orbital lesions, mostly in otolaryngology and maxillofacial surgeries. The authors undertook this anatomical study in order to contribute a neurosurgical perspective, exploring the anterior and middle cranial fossa areas through this purely endoscopic transorbital trajectory.METHODSAnatomical dissections were performed in 10 human cadaveric heads (20 sides) using 0° and 30° endoscopes.

Long-term survival in a patient with metastatic squamous cell lung carcinoma: A case report.

Non-small-cell lung cancer (NSCLC) is the most common malignancy in industrialized countries, with a 5-year survival rate of only ~15%, as the majority of the patients have advanced-stage disease at diagnosis and the treatment options are limited. Squamous cell carcinoma the second most frequent type of NSCLC and is closely associated with cigarette smoking. We herein present the case of a 72-year-old male smoker, diagnosed with stage IV squamous cell lung carcinoma, with a solitary brain metastasis.

Perspectives in immunotherapy: meeting report from the "Immunotherapy Bridge", Napoli, November 30th 2016.

The complex interactions between the immune system and tumors lead the identification of key molecules that govern these interactions: immunotherapeutics were designed to overcome the mechanisms broken by tumors to evade immune destruction. After the substantial advances in melanoma, immunotherapy currently includes many other type of cancers, but the melanoma lesson is essential to progress in other type of cancers, since immunotherapy is potentially improving clinical outcome in various solid and haematologic malignancies. Monotherapy in pre-treated NSCLC is studied and the use of nivolumab, pembrolizumab and atezolizumab as second-line of advanced NSCLC is demonstrated as well as first line monotherapy and combination therapy in metastatic NSCLC studied.

Statin Use and Survival in Patients with Metastatic Castration-resistant Prostate Cancer Treated with Abiraterone Acetate.

Background: Although statin use has been associated with favorable effects in various solid malignancies, no conclusive evidence is available at present. Statins are safe and inexpensive, and may synergize with novel antiandrogen agents abiraterone via pharmacokinetic interactions and decrease substrate availability for de novo androgen biosynthesis.

Objective: To determine whether statin use affects survival in patients with metastatic castration-resistant prostate cancer (mCRPC) treated with abiraterone.

ANMCO Position Paper: the use of non-vitamin K dependent new oral anticoagulant(s) in pulmonary embolism therapy and prevention.

The new oral anticoagulants (NOACs) have radically changed the approach to the treatment and prevention of thromboembolic pulmonary embolism. The authors of this position paper face, in succession, issues concerning NOACs, including (i) their mechanism of action, pharmacodynamics, and pharmacokinetics; (ii) the use in the acute phase with the 'double drug single dose' approach or with 'single drug double dose'; (iii) the use in the extended phase with demonstrated efficacy and with low incidence of bleeding events; (iv) the encouraging use of NOACs in particular subgroups of patients such as those with cancer, the ones under- or overweight, with renal insufficiency (creatinine clearance > 30 mL/min), the elderly (>75 years); (v) they propose a possible laboratory clinical pathway for follow-up; and (vi) carry out an examination on the main drug interactions, their potential bleeding risk, and the way to deal with some bleeding complications. The authors conclude that the use of NOACs both in the acute phase and in the extended phase is equally effective to conventional therapy and associated with fewer major bleeding events, which make their use in patients at higher risk of recurrences safer.

PSA declines and survival in patients with metastatic castration-resistant prostate cancer treated with enzalutamide: A retrospective case-report study.

Rationale: PSA responses have been associated with a survival benefit in patients treated with enzalutamide in retrospective analyses.

Patient Concerns: However the prognostic value of PSA declines in highly pretreated patients receiving enzalutamide remains to be defined.

Diagnoses And Interventations: Medical records of patients with documented mCRPC treated with enzalutamide between September 2011 and August 2016 were reviewed at multiple participating centers and assessed for overall survival (OS), PSA variations, and other variables of interest.

Fluorescein-Guided Surgery for High-Grade Glioma Resection: An Intraoperative "Contrast-Enhancer".

Background: Fluorescein sodium salt is widely used in medicine as fluorescein isothiocyanate and commonly named fluorescein (FL). This fluorophore has been used as a fluorescent tracer for many applications, especially in ophthalmic surgery. It was initially used in neuro-oncology in 1948 to control tumor resection margins.

Multimodal use of indocyanine green endoscopy in neurosurgery: a single-center experience and review of the literature.

During the last 10 years, microscope-integrated indocyanine green fluorescence (m-ICG) has been widely used for assessing real-time blood flow during aneurysm surgery. More recently, an endoscope-integrated indocyanine green fluorescence (e-ICG) has been adopted as a versatile tool during different endoscopic neurosurgical procedures. The purpose of the present report is to evaluate multimodal applications of e-ICG during different endonasal, intraventricular, aneurysm and brain tumor surgeries and provide technical nuances.

Transcranial Doppler Ultrasound: Incremental Diagnostic Role in Cryptogenic Stroke Part II.

Transcranial Doppler (TCD) ultrasonography is a noninvasive ultrasound study, which has been extensively applied in both outpatient and inpatient settings. Its main use in current clinical practice is the research for "Paradoxical Embolism," due to migration of thromboembolic material from systemic venous circulation to the left cardiac chambers and arterial circulation through cardiopulmonary shunts such as patent foramen ovale which represents an important cause of cryptogenic stroke, especially in patients under 55 years of age. In this review, we shall describe the incremental diagnostic role in cryptogenic stroke for this imaging modality.

Intraoperative Neurological Monitoring With Evoked Potentials During Carotid Endarterectomy Versus Cooperative Patients Under General Anesthesia Technique: A Retrospective Study.

Introduction: The best technique to evaluate contralateral carotid flow during carotid endarterectomy (CEA) is still debated; an accurate detection of efficient contralateral blood flow can avoid unnecessary shunt placement and its complications. The aim of this retrospective observational study was to evaluate and compare the safety and efficacy of general anesthesia with motor-evoked potential and somatosensory-evoked potentials (mSSEP and tcMEP) versus cooperative patients under general anesthesia (CPGA) technique for CEA. Primary outcome was the rate of technical failure.

Prognostic value of the neutrophil-to-lymphocyte ratio in the ARQ 197-215 second-line study for advanced hepatocellular carcinoma.

The ARQ 197-215 study randomized patients to tivantinib or placebo and pre-specified efficacy analyses indicated the predictive value of MET expression as a marker of benefit from tivantinib in hepatocellular carcinoma (HCC). We aimed to explore the neutrophil-to-lymphocyte ratio (NLR) in 98 ARQ 197-215 patients with available absolute neutrophil count and absolute lymphocyte count at baseline. The cut-off value used to define high versus low NLR was 3.

Purpose: To evaluate relationship between Meniere disease (MD) and chronic cerebrospinal venous insufficiency (CCSVI) using ultrasound, magnetic resonance (MR) imaging, and venography and to evaluate the effectiveness of angioplasty of the internal jugular vein (IJV) and azygos vein (AV) in reducing symptoms of MD.

Materials And Methods: Patients with a confirmed diagnosis of MD unresponsive to standard treatment underwent duplex ultrasound and MR imaging to diagnose CCSVI. Healthy volunteers were also studied to evaluate CCSVI in asymptomatic subjects.

Feasibility and outcome of interval debulking surgery (IDS) after carboplatin-paclitaxel-bevacizumab (CPB): A subgroup analysis of the MITO-16A-MaNGO OV2A phase 4 trial.

Background: Few data are available on the outcome of surgery after a bevacizumab-containing regimen. The MITO 16A- MaNGO OV2A phase 4 trial evaluates the outcomes of first-line CPB in a clinical-practice-like setting. Here we present the results of the subgroup of patients undergoing IDS after neoadjuvant treatment or suboptimal primary surgery.

Endoscopic transorbital route to the cavernous sinus through the meningo-orbital band: a descriptive anatomical study.

OBJECTIVE Exposure of the cavernous sinus is technically challenging. The most common surgical approaches use well-known variations of the standard frontotemporal craniotomy. In this paper the authors describe a novel ventral route that enters the lateral wall of the cavernous sinus through an interdural corridor that includes the removal of the greater sphenoid wing via a purely endoscopic transorbital pathway.

Endoscopic endonasal medial-to-lateral and transorbital lateral-to-medial optic nerve decompression: an anatomical study with surgical implications.

OBJECTIVE Different surgical routes have been used over the years to achieve adequate decompression of the optic nerve in its canal including, more recently, endoscopic approaches performed either through the endonasal corridor or the transorbital one. The present study aimed to detail and quantify the amount of bone removal around the optic canal, achievable via medial-to-lateral endonasal and lateral-to-medial transorbital endoscopic trajectories. METHODS Five human cadaveric heads (10 sides) were dissected at the Laboratory of Surgical Neuroanatomy of the University of Barcelona (Spain).

Trends in the use of partial nephrectomy for cT1 renal tumors: Analysis of a 10-yr European multicenter dataset.
