Landscape of immune cell gene expression is unique in predominantly WHO grade 1 skull base meningiomas when compared to convexity.

Sci Rep 2020 Jun 3;10(1):9065. Epub 2020 Jun 3.

Division of Neurosurgery, Department of Surgery, St. Michael's Hospital, Toronto, ON, Canada.

Modulation of tumor microenvironment is an emerging frontier for new therapeutics. However in meningiomas, the most frequent adult brain tumor, the correlation of microenvironment with tumor phenotype is scarcely studied. We applied a variety of systems biology approaches to bulk tumor transcriptomics to explore the immune environments of both skull base and convexity (hemispheric) meningiomas. Read More

Metastatic non-functional paraganglioma to the lung.

J Cardiothorac Surg 2020 May 11;15(1):82. Epub 2020 May 11.

Department of Thoracic Oncology, King Hussein Cancer Center, Amman, Jordan.

Introduction: Paragangliomas are rare endocrine tumors that arise from the extra-adrenal autonomic paraganglia and sympathetic paragangliomas usually secret catecholamines and are located in the sympathetic paravertebral ganglia of thorax, abdomen, and pelvis. In contrast, most parasympathetic paragangliomas are nonfunctional and located along the glossopharyngeal and vagal nerves in the neck and at the base of the skull. Such neoplasms, although rare, are clinically important because they may recur after surgical resection and 10% of them give rise to metastases causing death with the lymphatic nodes, bones, liver, and lungs being the most common locations.

Molecular Advances in Central Nervous System Mesenchymal Tumors.

Surg Pathol Clin 2020 Jun;13(2):291-303

Center for Skull Base and Pituitary Surgery, Department of Neurosurgery, Brigham and Women's Hospital, Harvard Medical School, Boston, MA, USA. Electronic address:

Mesenchymal tumors of the central nervous system (CNS) comprise an array of neoplasms that may arise from or secondarily affect the CNS and its immediate surroundings. This review focuses on meningiomas and solitary fibrous tumors, the most common primary CNS mesenchymal tumors, and discusses recent advances in unveiling the molecular landscapes of these neoplasms. An effort is made to underscore those molecular findings most relevant to tumor diagnostics and prognostication from a practical perspective. Read More

Prognostic impact of the "Sekhar grading system for cranial Chordomas" in patients treated with pencil beam scanning proton therapy: an institutional analysis.

Radiat Oncol 2020 May 6;15(1):96. Epub 2020 May 6.

Center for Proton Therapy, Paul Scherrer Institute, 5232 PSI West, Villigen, Switzerland.

Background: Skull base chordomas are rare and heterogeneously behaving tumors. Though still classified as benign they can grow rapidly, are locally aggressive, and have the potential to metastasize. To adapt the treatment to the specific needs of patients at higher risk of recurrence, a pre-proton therapy prognostic grading system would be useful. Read More

Chondromyxoid fibroma of the temporal bone: A rare case report.

Medicine (Baltimore) 2020 Mar;99(11):e19487

Department of Otorhinolaryngology, Beijing Tongren Hospital.

Rationale: Chondromyxoid fibroma (CMF) is a rare form of benign bone tumor and easily misdiagnosed as fibrosarcoma. Hence, to explore the clinical manifestations, diagnostic tests, and therapeutic procedures for temporal bone cartilage myxoid fibroma, it is important to optimize patient treatment and avoid overtreatment. Previous research has discussed cases of CMF, but this paper presents a systematic, complete, and comprehensive introduction of this disease based on this case and related literature. Read More

Glioma Migration Through the Corpus Callosum and the Brainstem Detected by Diffusion and Magnetic Resonance Imaging: Initial Findings.

Front Hum Neurosci 2019 25;13:472. Epub 2020 Feb 25.

Loghman Hakim Hospital, Shahid Beheshti University of Medical Sciences, Tehran, Iran.

: Glioma cell infiltration, in which the glioma tumor cells spread long distances from the primary location using white matter (WM) or blood vessels, is known as a significant challenge for surgery or localized chemotherapy and radiation therapy. Following the World Health Organization (WHO), the glioma grading system ranges from stages I to IV, in which lower-grade gliomas represent benign tumors, and higher grade gliomas are considered the most malignant. : We gathered magnetic resonance imaging (MRI) and diffusion tensor imaging (DTI) data for seven patients with right precentral gyrus-located tumors and six age- and sex-matched healthy subjects for analysis.

Incidence, risk factors, and outcomes of endoscopic sinus surgery after endoscopic skull-base surgery.

Int Forum Allergy Rhinol 2020 Apr 27;10(4):521-525. Epub 2020 Feb 27.

Department of Otorhinolaryngology-Head and Neck Surgery, University of Pennsylvania, Philadelphia, PA.

Background: Patients undergoing endoscopic resection of neoplasms with both sinonasal and skull base involvement can develop chronic rhinosinusitis (CRS) after treatment and may occasionally benefit from additional endoscopic sinus surgery (ESS).

Value of Routine Magnetic Resonance Imaging for the Preoperative Assessment of Cochlear Implant Candidates.

Cureus 2019 Dec 3;11(12):e6279. Epub 2019 Dec 3.

Otolaryngology, Neurotology and Skull Base Surgery, King Saud University, Riyadh, SAU.

Background The selection of an appropriate imaging technique for assessment before cochlear implantation is critical for precise diagnosis and management. While magnetic resonance imaging (MRI) is used for the diagnosis of several conditions, such as labyrinthitis ossificans, cochlear nerve deficiency, and neoplasms, high-resolution computed tomography (HRCT) provides excellent details of the temporal bone. However, it remains unclear whether routine MRI provides any additional benefits over HRCT. Read More

Department of Otolaryngology-Head and Neck Surgery, Princess Margaret Cancer Centre- University Health Network, Faculty of Medicine, University of Toronto, 610 University Avenue, 3-955, Toronto, ON, M5G 2M9, Canada.

Introduction: The extirpation of skull base malignancies may be associated with significant morbidity and can profoundly impact health related quality of life (HRQOL). In this review, we sought to provide an overview of HRQOL and the factors that influence it for patients with skull base malignancies.

Materials And Methods: Narrative review. Read More

The role of a post therapeutic surveillance program for sinonasal malignancies: Analysis of 417 patients.

Head Neck 2020 May 31;42(5):963-973. Epub 2019 Dec 31.

Division of Otorhinolaryngology, Department of Biotechnology and Life Sciences, University of Insubria, Ospedale di Circolo e Fondazione Macchi, Varese, Italy.

Background: Post therapeutic surveillance of head and neck neoplasms is a still debated issue in the current literature: although different works tried to establish frequency, modality, and efficacy of a routine follow-up, little evidence has been produced, in particular considering only sinonasal malignancies.

Methods: A retrospective review of patients treated for sinonasal malignancies in a single tertiary center and followed through a regular program of follow-up was carried out. Rate of recurrence, location, timing, diagnosis, and salvage treatment were the main data analyzed. Read More

Virtual Surgical Planning in Subscapular System Free Flap Reconstruction of Midface Defects.

Oral Oncol 2020 02 19;101:104508. Epub 2019 Dec 19.

Thomas Jefferson University, Department of Otolaryngology - Head & Neck Surgery, Philadelphia, PA, USA.

Objectives: Reconstruction of the midface has many inherent challenges, including orbital support, skull base reconstruction, optimizing midface projection, separation of the nasal cavity and dental rehabilitation. Subscapular system free flaps (SF) have sufficient bone stock to support complex reconstruction and the option of separate soft tissue components. This study analyzes the effect of virtual surgical planning (VSP) in SF for midface on subsite reconstruction, bone segment contact and anatomic position. Read More
