Supratentorial primitive neuroectodermal tumors in young children.
TO THE EDITOR: In the April issue of the Journal of Clinical Oncology, Timmermann et al suggest that radiotherapy plays a major role in the treatment of young children with supratentorial primitive neuroectodermal tumors (stPNET) and conclude that a delay in irradiation may compromise survival. Although stPNET are undoubtedly aggressive brain tumors and results of treatments are still disappoin...
متن کاملRadiologic characteristics of primitive neuroectodermal tumors in children.
Radiographic findings are reviewed in 31 children with primitive neural ectodermal tumors seen at the Hospital for Sick Children from 1962 through 1983. Seventeen children were initially evaluated with computed tomography (CT). Ten of these had both CT studies and angiography. The tumors were large, irregular, typically iso- to hyperdense, and showed dense, heterogeneous contrast enhancement. C...

متن کاملTreatment Outcome and Prognostic Molecular Markers of Supratentorial Primitive Neuroectodermal Tumors.
BACKGROUND To identify prognostic factors and define the optimal management of patients with supratentorial primitive neuroectodermal tumors (sPNETs), we investigated treatment outcomes and explored the prognostic value of specific molecular markers. METHODS A total of 47 consecutive patients with pathologically confirmed sPNETs between May 1985 and June 2012 were included. Immunohistochemica...
متن کاملSmall supratentorial, extraaxial primitive neuroectodermal tumor causing large intracerebral hematoma.
A 16-year-old boy presented with an unusual case of a supratentorial, extraaxial small round blue cell tumor of the central nervous system, which was most likely a primitive neuroectodermal tumor (PNET). Preoperative computed tomography and magnetic resonance imaging showed a large multistage hematoma in the left central region. Intraoperatively, a small, superficial tumorous lesion was found b...
