Reirradiation of primary CNS tumors
International Journal of Radiation Oncology*Biology*Physics, 1996Primary central nervous system (CNS) tumors are seldom reirradiated due to toxicity concerns and sparse clinical data regarding efficacy.We retrospectively reviewed 34 patients with primary brain tumors retreated with fractionated external beam irradiation at the University of California, San Francisco from 1977-1993.

Masson tumor (MT, papillary endothelial hyperplasia) is an exaggerated form of thrombus reorganization rarely occurring in the central nervous system (CNS), where it presents as a mass or hemorrhage in parenchyma, meninges, or venous sinuses. MT is subclassified as type 1 arising within a histologically normal vessel, type 2 associated with a ruptured ...

Neurofibromatosis type 1 (NF1) is an inherited cancer predisposition syndrome affecting 1 in 2,500 to 3,000 individuals worldwide. Key clinical features of NF1 include pigmentary abnormalities, learning disabilities, and orthopedic problems. Individuals with NF1 are prone to the development of benign peripheral nerve sheath tumors, and 15% to 20% of ...

Neurocognitive effects of CNS tumors
2013There is ample evidence that many children treated for brain tumors experience long-term neurocognitive deficits. The severity of those deficits is determined by a complex interaction of the child's genetic make-up and age, neuroanatomical damage caused by tumor and surgery, radiotherapy and chemotherapy, the psychosocial environment, and the intensity

Leukemia is the most common form of pediatric cancer. While the majority of other pediatric cancers involve the central nervous system (CNS), there are also a variety of tumors that arise from different parts of the body. This section will review the most common types of non-CNS tumors including leukemia, lymphoma, neuroblastoma, Wilms’ tumor, Ewing ...

High-grade malignant gliomas are the most common brain tumors of the adult life and account for about 30–45% of the primary human brain tumors. Of these, nearly 85% are glioblastoma multiforme (1).

Inflammatory Myofibroblastic Tumor with CNS Involvement
Oncology Research and Treatment, 2001Inflammatory myofibroblastic tumors (IMT) represent a spectrum of neoplasms that occur in the mesentery and retroperitoneum and less frequently in the mediastinum of children and young adults. Transformation into inflammatory fibrosarcoma and metastases are rare.We report the case of a 16-year-old patient with an inflammatory myofibroblastic tumor of ...

CNS primitive neuroectodermal tumors of childhood
Medical and Pediatric Oncology, 1984AbstractPrimitive neuroectodermal tumors (PNET) of the central nervous system in children are rare, highly malignant, cystic, and sometimes calcific, and hemorrhagic tumors sharply demarcated from adjacent brain. Microscopically they consist of small predominantly undifferentiated dark cells with neuronal, glial, and mesenchymal elements.
