Emerging tumor entities and variants of CNS neoplasms.
Since the appearance in 2000 of the World Health Organization (WHO) classification for central nervous system (CNS) neoplasms, numerous descriptions of new entities or variants have appeared in the literature. In the group of neuronal and mixed glioneuronal neoplasms are lesions with distinctive morphological features that are still not included in a precise classification, including extraventr...
متن کاملNew Brain Tumor Entities Emerge from Molecular Classification of CNS-PNETs
Primitive neuroectodermal tumors of the central nervous system (CNS-PNETs) are highly aggressive, poorly differentiated embryonal tumors occurring predominantly in young children but also affecting adolescents and adults. Herein, we demonstrate that a significant proportion of institutionally diagnosed CNS-PNETs display molecular profiles indistinguishable from those of various other well-defin...

متن کاملFine-grained Semantic Typing of Emerging Entities
Methods for information extraction (IE) and knowledge base (KB) construction have been intensively studied. However, a largely underexplored case is tapping into highly dynamic sources like news streams and social media, where new entities are continuously emerging. In this paper, we present a method for discovering and semantically typing newly emerging out-of-KB entities, thus improving the f...
متن کاملNQO1 C609T polymorphism in distinct entities of pediatric hematologic neoplasms.
BACKGROUND AND OBJECTIVES NAD(P)H:quinone oxidoreductase 1 (NQO1) is an enzyme that protects cells against mutagenicity from free radicals and toxic oxygen metabolites. The gene coding for NQO1 is subject to a genetic polymorphism at nucleotide position 609 (C-->T) of the human NQO1 cDNA. Heterozygous individuals (C/T) have intermediate activity and homozygotes for the variant allele (T/T) are ...
