Malignant Brain Tumors in Childhood
Although most brain tumors are sporadic, a number of pediatric brain tumor presentations are associated with recognized genetic syndromes. About 15–20% of children with neurofibromatosis (NF1) present with CNS neoplasms, usually gliomas of the optic pathways or low-grade tumors of the diencephalon, cerebral hemispheres, or posterior fossa (2). Low-grade gliomas associated with NF1 may be less a...
متن کاملPhotodynamic Therapy for Malignant Brain Tumors
Photodynamic therapy (PDT) using talaporfin sodium together with a semiconductor laser was approved in Japan in October 2003 as a less invasive therapy for early-stage lung cancer. The author believes that the principle of PDT would be applicable for controlling the invading front of malignant brain tumors and verified its efficacy through experiments using glioma cell lines and glioma xenograf...
متن کاملF-fluorothymidine kinetics of malignant brain tumors
Purpose F-labeled deoxy-fluorothymidine (FLT), a marker of cellular proliferation, has been used in PET tumor imaging. Here, the FLT kinetics of malignant brain tumors were investigated. Methods Seven patients with high-grade tumors and two patients with metastases had 12 studies. After 1.5 MBq/kg F-FLT had been administered intravenously, dynamic PET studies were acquired for 75 min. Images we...
متن کاملChemotherapy for malignant brain tumors of childhood.
During the past 3 decades, chemotherapeutic agents for the treatment of pediatric brain tumors have been extensively evaluated in a myriad of schedules, doses, and combinations. Remarkable advances in outcome have been achieved for certain children, notably those with medulloblastoma, but with a high cost to quality of life. In addition, the success achieved for medulloblastoma is offset by lac...
متن کاملVascular Attributes and Malignant Brain Tumors
Many diseases affect blood vessel morphology. This report analyzes vessel attributes (tortuosity, vessel density, radius, and terminal branch count) within 5 malignant gliomas as seen by high-resolution MR. Results are compared to those in the same anatomical region of 14 normal controls. All tumor patients had marked increases in vessel tortuosity and terminal branch count. These results raise...
