OBJECTIVE To screen for NF2 mutations in people with meningiomas. METHODS Lymphocyte or tumour DNA was analysed from 46 individuals from 36 families who presented with a meningioma at age < or =15 years without vestibular schwannoma (VS), or who had multiple meningiomas in adulthood before the diagnosis of VS. RESULTS Eight of 13 people with meningioma and other features of neurofibromatosi...

Although meningioma stem-like cells have been isolated and characterized, their therapeutic targeting remains a challenge. Meningioma sphere cells (MgSCs) with cancer stem cells properties show chemo- and radioresistance in comparison with meningioma adherent cells (MgACs). We tested the effect of valproic acid (VPA), a commonly used anti-epileptic drug, which passes the blood brain barrier, on...

Objective. It has been stated that brain cancers are an increasingly serious issue in many parts of the world. The aim of our study was to determine a possible relationship between Vitamin D receptor (VDR) gene polymorphisms and the risk of glioma and meningioma. Methods. We investigated the VDR Taq-I and VDR Fok-I gene polymorphisms in 100 brain cancer patients (including 44 meningioma cases a...

BACKGROUND Cervical lymph node metastases of meningioma represent an important diagnostic and treatment challenge. Not only has this entity been rarely described, but successful treatment has never been reported in the literature. METHODS AND RESULTS This case report was conducted using reviews of the literature. A 58-year-old man with a history of resected anaplastic meningioma was referred ...

INTRODUCTION The co-existence of pituitary adenoma and meningioma is extremely rare. It is even rarer in patients with no previous known risk factors for either tumour. Here, we present a case of synchronous non-functioning pituitary adenoma with suprasellar and olfactory groove meningiomas in a patient without previous irradiation. METHODS The tumours were diagnosed on MRI in the 65-year-old...

purpose: to evaluate of proton therapy (pt) for neurosurgery patients and is also to explain the need for this system in iran. methods: a literature review was conducted (1984–2016). the strategy included a combination of keywords including proton therapy, neck, neurosurgery, brain, head, tumor, spine, arteriovenous malformation (avms), cervical and spine in database of pubmed. new generation p...

We developed a new approach for detecting the gene amplification of cancer DNAs with restriction landmark genomic scanning (RLGS). In cancer research, much effort has been made to find the amplified loci of cancer DNAs, because many lines of evidence indicate association between oncogene amplification and carcinogenesis. Conventionally, such gene amplification has been detected by using Souther...

PM-11. DEVELOPMENT OF A HUMAN MENINGIOMA MOUSE XENOGRAFT MODEL WITH THE SPONTANEOUSLY IMMORTAL CELL LINE KCI-MENG1 Sharon Michelhaugh1, Anthony Guastella1, KaushikVaradarajan1, Lisa Polin1,2, Aliccia Bollig-Fischer1,2, Fazlul Sarkar1,2, and Sandeep Mittal1,2; Wayne State University, Detroit, MI, USA; Karmanos Cancer Institute, Detroit, MI, USA BACKGROUND: There is a paucity of effective therapi...

background: the most common complication of diagnostic and therapeutic endoscopic retrograde cholangiopancreatography (ercp) is acute pancreatitis. a number of therapeutic trials have been studied due to reduce the occurrence of postendoscopic retrograde cholangiopancreatography pancreatitis (pep) but many of them were unsuccessful. periampullary corticosteroid injection was proposed to use as ...

Meningioangiomatosis is a rare hamartomatous lesion or meningiovascular malformation in brain. In extremely rare condition, meningioma may occur together with meningioangiomatosis, and only 19 cases have been described in English literature until now. We now report a case of meningioangiomatosis-associated meningioma with atypical and clear cell variant. A 34-year-old man presented a 3-month hi...
