Central nervous system (CNS) metastases can occur with any primary systemic cancer, but some primary cancers such as melanoma have a specific predilection for the CNS. Brain metastasis is the most common CNS metastasis, occurring in 15% of all cancer patients (Posner, 1995). Leptomeningeal metastasis is less common, 3% to 8%, and epidural metastasis occurs in approximately 5% of cases (Posner, ...

Central nervous system (CNS) tumors constitute a heterogeneous group of neoplasms that share a considerable morbidity and mortality rate. Recent advances in the underlying oncogenic mechanisms of these tumors have led to new classification systems, which, in turn, allow for a better diagnostic approach and therapeutic planning. Most of these neoplasms occur sporadically and several risk factors...

T he objective of CBTRUS Statistical Report: Primary Brain and Central Nervous System Tumors Diagnosed in the United States in 2006-2010 is to provide a current comprehensive review of the descriptive epidemiology of primary brain and central nervous system (CNS) tumors in the United States population. The Central Brain Tumor Registry of the United States (CBTRUS) obtained data on all newly dia...

Managing a CNS neoplasm during pregnancy presents complex challenges, and population-based studies are lacking. We designed a retrospective cohort study using the Nationwide Inpatient Sample (NIS) to investigate pregnancy outcomes in women with CNS neoplasms. We constructed a logistic regression model for maternal mortality, preterm labor, intrauterine growth restriction (IUGR), and Caesarean d...

Neoplasms of the central nervous system (CNS) are a pathologically diverse group of benign and malignant tumors for which a variety of management strategies, including observation, surgery, radiation therapy, and/or chemotherapy, are employed. Shown in Table 1 are the usual radiation doses used to treat primary and metastatic brain and spinal cord tumors, which span a broad range of total doses...

The treatment of brain tumors and neurodegenerative diseases, represents an ongoing challenge. In Central Nervous System (CNS) the achievement of therapeutic concentration of chemical agents is complicated by the presence of distinct set of efflux proteins, such as ATP-Binding Cassette (ABC) transporters localized on the Blood-Brain Barrier (BBB). The activity of ABC transporters seems to be a ...

Central nervous system primitive neuro-ectodermal tumors (CNS-PNETs), have recently been re-classified in the most recent 2016 WHO Classification into a standby catch all category, "CNS Embryonal Tumor, not otherwise specified" (CNS embryonal tumor, NOS) based on epigenetic, biologic and histopathologic criteria. CNS embryonal tumors (NOS) are a rare, histologically and molecularly heterogeneou...

PURPOSE Primary central nervous system (CNS) tumors represent a diverse group of tumor types with heterogeneous molecular mechanisms that underlie their formation and maintenance. CNS tumors depend on angiogenesis and often display increased activity of ErbB-associated pathways. Current nonspecific therapies frequently have poor efficacy in many of these tumor types, so there is a pressing need...

BACKGROUND Central nervous system (CNS) primitive neuroectodermal tumors (PNETs) are malignant primary brain tumors that occur in young infants. Using current standard therapy, up to 80% of the children still dies from recurrent disease. Cellular immunotherapy might be key to improve overall survival. To achieve efficient killing of tumor cells, however, immunotherapy has to overcome cancer-ass...

The homeodomain transcription factor, NANOG, along with OCT3/4 (POU5F1) and SOX2, is part of the core set of transcription factors that maintain embryonic stem cell self-renewal and pluripotency. Expression of NANOG has been detected in fetal germ cells and in gonadal germ cell tumors. To assess the diagnostic utility of NANOG in central nervous system (CNS) germ cell tumors, we analyzed its ex...
