Orthotopic induction of CH157MN convexity and skull base meningiomas into nude mice using stereotactic surgery and MRI characterization.

Animal Model Exp Med 2019 Mar 20;2(1):58-63. Epub 2019 Feb 20.

Bracco Research Centre Bracco Imaging SpA Colleretto Giacosa TO Italy.

Meningioma in vivo research is hampered by the difficulty of establishing an easy and reproducible orthotopic model able to mimic the characteristics of a human meningioma. Moreover, leptomeningeal dissemination and high mortality are often associated with such orthotopical models, making them useless for clinical translation studies. An optimized method for inducing meningiomas in nude mice at two different sites is described in this paper and the high reproducibility and low mortality of the models are demonstrated. Read More

World Neurosurg 2019 Apr 4. Epub 2019 Apr 4.

Department of Neurosurgery, Fudan University Shanghai Cancer Center, Department of Oncology, Shanghai Medical College, Fudan University, Shanghai 200032, China. Electronic address:

Background: Preoperative embolization (POE) of meningioma has been established to facilitate surgical resection, which may reduce intraoperative blood loss and surgical time. However, no consensus has been achieved in meningioma treatment and no meta-analysis has been conducted. The purpose of this study was to perform a systematic review and meta-analysis and provide evidence of the efficacy of meningioma treatment with POE and direct surgery. Read More

Risk group-adapted adjuvant radiotherapy for WHO grade I and II skull base meningioma.

J Cancer Res Clin Oncol 2019 May 5;145(5):1351-1360. Epub 2019 Apr 5.

Department of Radiation Oncology, Gangnam Severance Hospital, Yonsei University College of Medicine, 211, Eonju-ro, Gangnam-gu, Seoul, 06273, South Korea.

Purpose: Salvage treatment including surgery and radiotherapy (RT) for recurrent or progressive meningioma is not an easy task, especially for the skull base location. And yet, criteria for adjuvant radiotherapy after initial surgery are not clearly defined for WHO grade I/II meningioma. We determined prognostic factors for recurrence and evaluated the benefit of risk group-adapted adjuvant RT for WHO grade I/II meningioma in the skull base. Read More

Meningioma metastases: incidence and proposed screening paradigm.

J Neurosurg 2019 04 5:1-9. Epub 2019 Apr 5.

Departments of1Neurological Surgery.

Objective: Extracranial meningioma metastases are uncommon, occurring in less than 1% of patients diagnosed with meningioma. Due to the rarity of meningioma metastases, patients are not routinely screened for distant disease. In this series, we report their experience with meningioma metastases and results of screening for metastases in select patients with recurrent meningiomas. Read More

Application of MR morphologic, diffusion tensor, and perfusion imaging in the classification of brain tumors using machine learning scheme.

Neuroradiology 2019 Apr 4. Epub 2019 Apr 4.

Department of Diagnostic Imaging, Sheba Medical Center, Ramat-Gan, Israel, 2 Sheba Rd, 52621, Ramat Gan, Israel.

Purpose: While MRI is the modality of choice for the assessment of patients with brain tumors, differentiation between various tumors based on their imaging characteristics might be challenging due to overlapping imaging features. The purpose of this study was to apply a machine learning scheme using basic and advanced MR sequences for distinguishing different types of brain tumors.

Methods: The study cohort included 141 patients (41 glioblastoma, 38 metastasis, 50 meningioma, and 12 primary central nervous system lymphoma). Read More

Expression of Cathepsins B, D, and G in WHO Grade I Meningioma.

Front Surg 2019 12;6. Epub 2019 Mar 12.

Gillies McIndoe Research Institute, Wellington, New Zealand.

We have recently demonstrated the presence of putative tumor stem cells (TSCs) in World Health Organization (WHO) grade I meningioma (MG) localized to the microvessels, which expresses components of the renin-angiotensin system (RAS). The RAS is known to be dysregulated and promotes tumorigenesis in many cancer types, including glioblastoma. Cathepsins B, D, and G are isoenzymes that catalyze the production of angiotensin peptides, hence providing bypass loops for the RAS. Read More

Department of Pathology and Laboratory Medicine, King Abdulaziz Medical City, King Saud bin Abdulaziz University for Health Sciences, King Abdullah International Medical Research Center, Riyadh, Saudi Arabia.

Background: Although meningiomas are considered benign, encapsulated brain tumors, their distinct intracranial location can lead to devastating complications. Despite being a highly vascularized tumor, a rarely reported complication of meningioma is hemorrhage. To the best of our knowledge, only 19 cases of meningioma presenting with a subdural hematoma have been reported in the literature. Read More

Application of Dextroscope in a Rare Type of Angiomatous Meningioma Characterized With Coral-Like Vessels.

J Craniofac Surg 2019 Mar 28. Epub 2019 Mar 28.

Department of Neurosurgery, Beijing Tiantan Hospital.

A 43-year-old female diagnosed with meningioma was admitted to our department. Preoperative imaging revealed a spherical lesion located in the sphenoid ridge with obvious enhancement and inhomogeneous density into 3 layers on magnetic resonance (MR) images, coral-like vessel images inside the tumor was obtained after the raw computed tomography angiography data were imported into the Dextroscope virtual-reality system. Due to her progressive headache and visual deterioration, surgery was performed after comprehensive study in the Dextroscope system, details about the correlation among skull base, lesion, branches of internal carotid artery, and vessels inside the tumor were well demonstrated in this system.

Low expression of pentraxin 3 and nuclear factor-like 2 implying a relatively longer overall survival time in gliomas.

Chin J Physiol 2019 Jan-Feb;62(1):35-43

Department of Pathology, Tri-Service General Hospital; Graduate Institute of Pathology and Parasitology, National Defense Medical Center, Taipei, Taiwan.

Pentraxin 3 (PTX3) and nuclear factor-like 2 (Nrf2) are known to induce tumor progression in certain malignancies but act as tumor suppressors in other human neoplasms. In this study, we not only tested the association between PTX3 expression and the World Health Organization (WHO) tumor grading system but also evaluated overall patient survival under variable expression of PTX3 and Nrf2 in primary brain tumors (PBTs). Immunohistochemistry (IHC) was performed for PTX3 and Nrf2 in 10 nonneoplastic brain tissues and 197 PBTs. Read More
