Ewingʼs sarcoma and peripheral primitive neuroectodermal tumor

Current Opinion in Oncology, 1994
Disease-free survival for patients with small sarcomas of bone has been impressively improved with the use of intensive combination chemotherapy and safe local control with surgery or radiation. The ability of monoclonal antibodies to recognize different antigens has allowed new insights into the histogenesis and has distinguished a neural variant now ...

What’s in a name?

Strahlentherapie und Onkologie, 2013
Intracranial peripheral primitive neuroectodermal tumors (P-PNET) are extremely rare. They can be easily misdiagnosed as central nervous system primitive neuroectodermal tumors (CNS-PNET) or meningiomas. Little is known about the optimal treatment and prognosis of these tumors.We evaluated the treatment and outcome of 17 patients with intracranial ...
