Abstract
Malignant peripheral nerve sheath tumors (MPNSTs) are aggressive, invasive cancer that comprise around 10% of all soft tissue sarcomas and develop in about 8-13% of patients with Neurofibromatosis Type 1. They are associated with poor prognosis and are the leading cause of mortality in NF1 patients. MPNSTs can also develop sporadically or following exposure to radiation. There is currently no effective targeted therapy to treat MPNSTs and surgical removal remains the mainstay treatment. Unfortunately, surgery is not always possible due to the size and location of the tumor, thus, a better understanding of MPNST initiation and development is required to design novel therapeutics. Here, we provide an overview of MPNST biology and genetics, discuss findings regarding the developmental origin of MPNST, and summarize the various model systems employed to study MPNST. Finally, we discuss current management strategies for MPNST, as well as recent developments in translating basic research findings into potential therapies.

Abstract
Malignant peripheral nerve sheath tumors (MPNSTs) are aggressive soft tissue sarcomas that can arise most frequently in patients with neurofibromatosis type 1 (NF1). Despite an increasing understanding of the molecular mechanisms that underlie these tumors, there remains limited therapeutic options for this aggressive disease. One potentially critical finding is that a significant proportion of MPNSTs exhibit recurrent mutations in the genes EED or SUZ12, which are key components of the polycomb repressive complex 2 (PRC2). Tumors harboring these genetic lesions lose the marker of transcriptional repression, trimethylation of lysine residue 27 on histone H3 (H3K27me3) and have dysregulated oncogenic signaling. Given the recurrence of PRC2 alterations, intensive research efforts are now underway with a focus on detailing the epigenetic and transcriptomic consequences of PRC2 loss as well as development of novel therapeutic strategies for targeting these lesions. In this review article, we will summarize the recent findings of PRC2 in MPNST tumorigenesis, including highlighting the functions of PRC2 in normal Schwann cell development and nerve injury repair, as well as provide commentary on the potential therapeutic vulnerabilities of a PRC2 deficient tumor cell.

Abstract
Malignant peripheral nerve sheath tumors (MPNSTs) are heterogeneous, highly aggressive tumors with no widely effective treatment other than surgery. Genomic architecture of MPNST is similar to other soft tissue sarcomas, with a relatively modest burden of single nucleotide variants and an elevated frequency of copy-number alterations. Recent advances in genomic studies identified previously unrecognized critical involvement of polycomb repressor complex 2 (PRC2) core components SUZ12 and EED in transition to malignancy. Notably, somatic changes in NF1, CDKN2A/B, and PRC2 are found in most MPNST regardless of their etiology (e.g. neurofibromatosis type 1-associated vs. sporadic vs. radiation-induced), indicating that similar molecular mechanisms impact pathogenesis in these neoplasms. The timing and specific order of genetic or epigenetic changes may, however, explain the typically poorer prognosis of NF1-associated MPNSTs. Studies that reveal genes and regulatory pathways uniquely altered in malignancies are essential to development of targeted tumor therapies. Characterization of MPNST molecular profiles may also contribute to tools for earlier detection, and prediction of prognosis or drug response. Here we review the genetic discoveries and their implications in understanding MPNST biology.

Abstract
OBJECTIVES To evaluate nutrient intake among adult neurofibromatosis type 1 (NF1) patients. METHODS A cross-sectional study of 60 NF1 patients (29 men, 31 women) who were ≥18 y old and were evaluated from September 2012 to September 2013 in a neurofibromatosis outpatient reference center. Patients underwent nutritional assessment, including anthropometric and dietary data collection. Food intake was evaluated using three, non-consecutive, self-reported 24-h dietary recall surveys, and nutrient intake was analyzed according to the recommendations of the dietary reference intake document. RESULTS Forty-three patients (72%) recorded energy consumption lower than the estimated daily energy requirement (EER). Men (25/29, 86.2%) were more likely to fail to meet their target EER, compared to women (18/31, 58.1%) (P = 0.016). Inadequate intake of vitamin D, magnesium, calcium, and pyridoxine was noted between men and women, and all patients consumed excess sodium. NF1 patients did not consume adequate amounts of fiber or vitamins A and C. Excessive consumption of saturated fatty acids and lipids was also observed in both male and female patients. CONCLUSIONS In this study, NF1 patients consumed an unhealthy diet that was rich in fats and sodium and lacking in fiber, vitamins, and minerals. Further studies are needed to investigate the role of these dietary and nutritional patterns in the severity of the clinical manifestations of NF1.

Abstract
Abstract
BACKGROUND AND IMPORTANCE
Malignant peripheral nerve sheath tumors are the most common malignant mesenchymal tumors of soft tissues, but they are very rare when found to arise from a cranial nerve and when not in association with neurofibromatosis. These tumors are highly malignant and carry a poor prognosis with survival usually less than 6 months.
CLINICAL PRESENTATION
The authors report the case of a 23-year-old female with no history of phakomatoses, previous irradiation, or known genetic disorders, who presented with a malignant peripheral nerve sheath tumor of the vestibulocochlear nerve and brainstem. Multiple staged skull base approaches were carried out with maximal possible resection. Adjunctive therapies including standard radiation therapy, intensity-modulated radiation therapy, and stereotactic gamma knife radiosurgery were used with an ultimate patient survival of 27 months.
CONCLUSION
To our knowledge, this is the first report describing a patient with a malignant peripheral nerve sheath tumor of the vestibulocochlear nerve and brainstem treated with staged surgical approaches in conjunction with multiple forms of radiotherapy and having a significant survival of more than 2 years.

Abstract
OBJECTIVES The incidence of malignant peripheral nerve sheath tumor (MPNST) is approximately 0.001%. Those involving intracranial nerves are even more exceptional. Little information is available concerning work up and management. Our objective is: (1) to review all cases of intracranial MPNST described in the literature, (2) to highlight the suspicion of intracranial MPNST, (3) to identify the gross pathology, the histopathology, the immunohistochemistry, (4) to discuss the differential diagnosis, the treatment, the recurrence rate, the follow-up, the incidence of metastasis and the prognosis. METHODS We reviewed English, Spanish and French literature published from 1950 to date. We used the following Keywords: "malignant peripheral nerve sheath tumor", "cranial nerve", "neurosarcoma", "malignant schwannoma", "neurofibroma", "malignant neurofibroma" and "nerve tumor". We considered cases where MPNST involved an intracranial cranial nerve. The results yielded 20 relevant studies, in which 31 patient's records were transcribed. We also added our case to this series. RESULTS We identified 32 cases of cranial MPNST including our case. The age ranged from 5 to 75 years old with most patients being in the 5th and 6th decade. Male to female ratio is 2.5:1. Most cases are developed sporadically (50%), 31% arise from a malignant transformation of schwannoma and 19% from a neurofibroma. Imaging findings were not specific. The cranial nerve VIII is the most involved (15/32), followed by the Vth (10/32) and the VIIth (5/32). 4 cases had neurofibromatosis type 1 and 2 had neurofibromatosis type 2. MPNST will strongly express protein S-100 and collagen IV-laminin. 13 cases were treated with radiotherapy for tumor recurrence and metastasis. In these cases the survival rate was better than the cases without radiotherapy. Fatal outcome occurred in 66% of patients whereas 19% were reported alive with or without complications. The seven cases reported to have metastasis were entirely to the spine. The mean time of recurrence or metastasis is 12.2 months. CONCLUSION MPNST of cranial nerves are very rare. In neurofibroma, even though MPNST is mainly associated to type 1, we should keep in mind its association to NF2. Mainstay of treatment is radical resection with adjuvant radiotherapy. Inaccessibility of cranial MPNST may explain the subtotal resection and thus the poor prognosis. Metastasis to the spinal cord is the most frequent one. A close postoperative follow-up is mandatory to eliminate recurrence.

Abstract
Ras leads an important signaling pathway that is deregulated in neurofibromatosis type 1 and malignant peripheral nerve sheath tumor (MPNST). In this study, we show that overactivation of Ras and many of its downstream effectors occurred in only a fraction of MPNST cell lines. RalA, however, was overactivated in all MPNST cells and tumor samples compared to nontransformed Schwann cells. Silencing Ral or inhibiting it with a dominant-negative Ral (Ral S28N) caused a significant reduction in proliferation, invasiveness, and in vivo tumorigenicity of MPNST cells. Silencing Ral also reduced the expression of epithelial mesenchymal transition markers. Expression of the NF1-GTPase-related domain (NF1-GRD) diminished the levels of Ral activation, implicating a role for neurofibromin in regulating RalA activation. NF1-GRD treatment caused a significant decrease in proliferation, invasiveness, and cell cycle progression, but cell death increased. We propose Ral overactivation as a novel cell signaling abnormality in MPNST that leads to important biological outcomes with translational ramifications.

Abstract
INTRODUCTION Primary malignant neoplasms of nerve sheath origin are rare, highly aggressive tumours that account for no more than 5% of all soft tissue sarcomas. In the head and neck where the great majority of peripheral nerve neoplasms are benign, as in the rest of the body, malignant peripheral nerve sheath tumours (MPNSTs) are unusual lesions. PATIENT A case of a large MPNST is reported, which originated in the left temporalis muscle of a 74-year-old man who did not suffer from von Recklinghausen's disease. It had been treated as an abscess for a long time. DISCUSSION The clinicopathologic properties of this neoplasm have been widely discussed and the emphasis is on the need for its early identification since the tumour's non-specific symptoms may result in delayed diagnosis and treatment. CONCLUSION To date, to our knowledge, no case of MPNST located in the temporalis muscle has been described. The rarity of the tumour along with its clinical appearance and the vague symptoms may result in delayed referral and thus the tumour being quite large when diagnosed.

Abstract
PURPOSE OF REVIEW The intention of the authors is to provide the reader with an overview of the recent advances in the diagnosis and treatment of nerve sheath tumors. Vestibular schwannomas, neurogenetic syndromes such as schwannomatosis and multiple isolated neurofibromas, and malignant peripheral nerve sheath tumors are covered in this review. RECENT FINDINGS Over the last year, literature focusing on different management strategies for patients with vestibular schwannomas dominated the field. Surgical options for this group of patients are changing. Stereotactic radiation is also employed more frequently with promising results. New insights into the biology of peripheral nerve tumor development and growth, including expression of vascular endothelial growth factor by vestibular schwannomas and the role of Notch signaling in malignant transformation of benign neurofibromas have been described. Diagnostic criteria for schwannomatosis, a recently described condition, are being developed. Several cases of multiple isolated neurofibromas and spinal neurofibromas were reported. SUMMARY Peripheral nerve tumors are classified according to the specific features of cellular differentiation. The most common types include schwannoma and neurofibroma. These tumors can occur sporadically or as manifestations of genetic syndromes such as neurofibromatosis types 1 and 2 or schwannomatosis. The majority of peripheral nerve tumors are benign but malignant transformation does occur. Metastatic tumors can also affect peripheral nerves. The diagnostic modality of choice is magnetic resonance imaging. Positron emission tomography is a useful technique in the presurgical differentiation between benign and malignant peripheral nerve sheath tumors. Treatment is directed towards symptomatic control. Surgery, radiation and, in rare instances, chemotherapy are the major treatment modalities employed.
