An update on the central nervous system manifestations of neurofibromatosis type 1.

Acta Neuropathol 2019 Apr 8. Epub 2019 Apr 8.

Department of Pathology, Johns Hopkins University School of Medicine, Sheikh Zayed Tower, Room M2101, 1800 Orleans Street, Baltimore, MD, 21231, USA.

Neurofibromatosis 1 (NF1) is an autosomal dominant genetic disorder that presents with variable phenotypes as a result of mutations in the neurofibromatosis type 1 (NF1) gene and subsequently, abnormal function of the protein product, neurofibromin. Patients with NF1 are at increased risk for central nervous system (CNS) manifestations including structural, functional, and neoplastic disease. The mechanisms underlying the varied manifestations of NF1 are incompletely understood, but the loss of functional neurofibromin, resulting in sustained activation of the oncoprotein RAS, is responsible for tumorigenesis throughout the body, including the CNS.

Targeted inhibition of the dual specificity phosphatases DUSP1 and DUSP6 suppress MPNST growth via JNK.

Clin Cancer Res 2019 Apr 1. Epub 2019 Apr 1.

Division of Experimental Hematology and Cancer Biology, Cincinnati Children's Hospital Medical Center

Purpose: In Neurofibromatosis Type 1 (NF1) and in highly aggressive malignant peripheral nerve sheath tumors (MPNSTs), constitutively active RAS-GTP and increased MAPK signaling are important in tumorigenesis. Dual specificity phosphatases (DUSPs) are negative regulators of MAPK signaling that dephosphorylate p38, JNK and ERK in different settings. While often acting as tumor suppressors, DUSPs may also act as oncogenes, helping tumor cells adapt to high levels of MAPK signaling. Read More

Heat shock factor 1 (HSF1)-targeted anticancer therapeutics: overview of current preclinical progress.

Expert Opin Ther Targets 2019 Mar 31:1-9. Epub 2019 Mar 31.

a Department of Urology , Tokyo Medical and Dental University , Tokyo , Japan.

Introduction: The heat shock factor 1 (HSF1) plays a pivotal role in guarding proteome stability or proteostasis by induction of heat shock proteins (HSPs). While HSF1 remains mostly latent in unstressed normal cells, it is constitutively active in malignant cells, rendering them addicted to HSF1 for their growth and survival. HSF1 affects tumorigenesis, cancer progression, and treatment resistance by preserving cancer proteostasis, thus suggesting disruption of HSF1 activity as a potential anticancer strategy. Read More

Clinical, radiological features and surgical strategies for 23 NF1 patients with intraorbital meningoencephalocele.

Neurol Sci 2019 Mar 13. Epub 2019 Mar 13.

Department of Neurosurgery, Beijing Tiantan Hospital, Capital Medical University, Beijing, 100050, China.

Intraorbital meningoencephalocele is a rare manifestation of neurofibromatosis type 1 (NF1) caused by secondary changes in sphenoid dysplasia, and it seriously affects patients' vision and facial appearance. We retrospectively analyzed the clinical data of 23 patients with NF1 and intraorbital meningoencephalocele, summarized the surgical strategies employed, and evaluated their clinical efficacy in order to better understand its management in clinical practice, establish a reasonable surgical strategy, and assess prognosis. Before surgery, 22 patients had unilateral pulsatile exophthalmos, 18 patients had significant visual impairment, and 13 patients had ptosis associated with an orbital plexiform neurofibroma (PNF).

Recurrent SMARCB1 Inactivation in Epithelioid Malignant Peripheral Nerve Sheath Tumors.

Am J Surg Pathol 2019 Mar 8. Epub 2019 Mar 8.

Department of Pathology.

Epithelioid malignant peripheral nerve sheath tumors (EMPNST) are characterized by diffuse S-100 and SOX10 positivity, frequent immunohistochemical loss of SMARCB1 expression (70%), and rare association with neurofibromatosis type 1. Some cases arise in a preexisting epithelioid schwannoma (ESCW), which also show SMARCB1 loss in 40% of cases. To date, little is known about the genomic landscape of this distinctive variant of malignant peripheral nerve sheath tumor. Read More

Neurofibromatosis Type 1: Review of Cutaneous and Subcutaneous Tumor Treatment on Quality of Life.

Plast Reconstr Surg Glob Open 2019 Jan 18;7(1):e1982. Epub 2019 Jan 18.

Feinberg School of Medicine, Northwestern University, Chicago, Ill.

Background: Neurofibromatosis Type 1 (NF1) is the most common type of neurogenetic disorder with a worldwide incidence of between 1 in 2,600 and 1 in 3,000. NF1 has a wide range of manifestations; as a result, NF1 has no "public persona." Beginning at puberty and continuing thereafter patients may grow cutaneous and subcutaneous tumors (neurofibromas) in large numbers, which cause severe problems with appearance, which are similar in severity to those of psoriasis.

Spontaneous massive haemothorax in the peri-partum period of an undiagnosed neurofibromatosis type 1 patient - A surgical perspective.

Med J Malaysia 2019 Feb;74(1):99-101

Hospital Taiping, Department of Surgery, Perak, Malaysia.

Acute massive haemothorax is a life-threatening situation, which is often associated with a preceding trauma. However, spontaneous haemothorax is a rare occurrence, especially in pregnancy. Spontaneous haemothorax in the immediate post-partum period secondary to a ruptured intercostal AVM is extremely rare more so in the background of an undiagnosed neurofibromatosis. Read More

The Arg1038Gly missense variant in the NF1 gene causes a mild phenotype without neurofibromas.

Mol Genet Genomic Med 2019 Mar 6:e616. Epub 2019 Mar 6.

Department of Women's and Children's Health, Clinical Genetics Unit, University of Padova, Padova, Italy.

Background: Neurofibromatosis type 1 (NF1) is an autosomal dominant condition caused by inactivating mutations of the NF1 gene. The wide allelic heterogeneity of this condition, with more than 3,000 pathogenic variants reported so far, is paralleled by its high clinical variability, which is observed even within the same family. The definition of genotype-phenotype correlations has been hampered by the complexity of the NF1 gene and, although a few exceptions have been recognized, the clinical course remains unpredictable in most patients.

Childhood brain tumors: current management, biological insights, and future directions.

J Neurosurg Pediatr 2019 Mar;23(3):261-273

Brain tumors are the most common solid tumors in children, and, unfortunately, many subtypes continue to have a suboptimal long-term outcome. During the last several years, however, remarkable advances in our understanding of the molecular underpinnings of these tumors have occurred as a result of high-resolution genomic, epigenetic, and transcriptomic profiling, which have provided insights for improved tumor categorization and molecularly directed therapies. While tumors such as medulloblastomas have been historically grouped into standard- and high-risk categories, it is now recognized that these tumors encompass four or more molecular subsets with distinct clinical and molecular characteristics.

"Transforming the Beast to A Beauty"- Fifteen Years into the Making - Case Report of Congenital Neurofibromatosis.

Open Access Maced J Med Sci 2019 Feb 31;7(3):388-391. Epub 2019 Jan 31.

Institute of Pathology, Medical Faculty, Ss. Cyril and Methodius University of Skopje, Skopje, Republic of Macedonia.

Background: In 1882, the German pathologist Friedrich Daniel von Recklinghausen described a series of patients with a combination of cutaneous lesions and tumours of the peripheral and central nervous system. Succeeding this paper, all of the patients with similar symptoms were given the diagnosis "von Recklinghausen disease". In the 20th century, a distinction was made between Neurofibromatosis type 1 (NF1) and Neurofibromatosis type 2 (NF2) with the help of molecular testing. Read More
