Neuroectodermal Tumors of the Central and Peripheral Nervous System

Central nervous system primitive neuroectodermal tumors: still a useful classification?

Diagnostic Accuracy of Squash Preparations in Central Nervous System Tumors

Background & Objectives: The accurate assessment of the diseased tissue is fundamental to the diagnosis and management of disorders of the central nervous system (CNS). The ‛squash’ or ‛crush’ technique has been universally employed in the intraoperative diagnosis of CNS tumors. The aim of our study was to evaluate the accuracy of squash preparation in diagnosing CNS tumors by comparing with hi...

Central nervous system tumors.

Central nervous system tumors are relatively common in the United States, with more than 40,000 cases annually. Although more than half of these tumors are benign, they can cause substantial morbidity. Malignant primary brain tumors are the leading cause of death from solid tumors in children and the third leading cause of death from cancer in adolescents and adults aged 15 to 34 years. Common ...

Pediatric Primitive Neuroectodermal Tumors of the Central Nervous System Differentially Express Granzyme Inhibitors.

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...

Reduction to homozygosity and gene amplification in central nervous system primitive neuroectodermal tumors of childhood.

The loss of genetic material from specific chromosomal locations has been identified for a number of pediatric tumors. This loss has been taken as evidence for the importance of tumor suppressor genes at these loci in the genesis of these tumors. One of these pediatric tumors, the primitive neuroectodermal tumor of the central nervous system, has not been well studied. In this report, an analys...
