Within three weeks of definitive surgical intervention, 467 patients with histologically proved malignant glioma were randomized to receive one of four treatment regimens: semustine (MeCCNU), radiotherapy, carmustine (BCNU) plus radiotherapy, or semustine plus radiotherapy. We analyzed the data for the total randomized population and for the 358 patients in(More)
A method for registering three-dimensional CT, MR, and PET data sets that require no special patient immobilization or other precise positioning measures was adapted to high-resolution SPECT and MRI and was applied in 14 subjects (five normal volunteers, four patients with dementia (Alzheimer's disease), two patients with recurrent glioblastoma, and three(More)
A controlled, prospective, randomized study evaluated the use of 1,3-bis(2-chloroethyl)-1-nitrosourea (BCNU) and/or radiotherapy in the treatment of patients who were operated on and had histological confirmation of anaplastic glioma. A total of 303 patients were randomized into this study, of whom 222 (73%) were within the Valid Study Group (VSG), having(More)
OBJECTIVE We describe the development and implementation of a new open configuration magnetic resonance imaging (MRI) system, with which neurosurgical procedures can be performed using image guidance. Our initial neurosurgical experience consists of 140 cases, including 63 stereotactic biopsies, 16 cyst drainages, 55 craniotomies, 3 thermal ablations, and 3(More)
We have used three-dimensional reconstruction magnetic resonance imaging techniques to understand the anatomic complexity of operative brain lesions and to improve preoperative surgical planning. We report our experience with 14 cases, including intra- and extra-axial tumors and a vascular malformation. In each case, preoperative planning was performed(More)
BACKGROUND The spread of systemic cancer to the brain is a common complication for cancer patients. Conventional radiotherapy offers modest palliation, and surgery is helpful only for the patient with a single metastasis in an accessible location. Stereotactic radiosurgery, a technique that permits the precise delivery of a high dose of radiation to a small(More)
Thirteen patients, 11 women and 2 men, developed sensory and autonomic neuronopathies in association with features of primary Sjögren's syndrome. In 11, Sjögren's syndrome had not been previously diagnosed at the time of neurological presentation. All had prominent loss of kinesthesia and proprioception. Pain and thermal sensibility were less severely(More)
PURPOSE To evaluate the impact of stereotactic radiosurgery on the survival of patients treated with malignant gliomas. METHODS AND MATERIALS A total of 115 patients from three institutions (75 from the Joint Center for Radiation Therapy, 30 from the University of Wisconsin, and 10 from the University of Florida) were treated with a combination of(More)
PURPOSE To retrospectively evaluate the initial clinical results of stereotactic radiosurgery (SRS) and fractionated stereotactic radiotherapy (SRT) for pituitary adenomas with regard to tumor and hormonal control and adverse effects of the treatment. SUBJECTS AND METHODS Forty-eight patients with pituitary adenoma who underwent SRS or SRT between(More)
PURPOSE Recent randomized trials of selected patients with single brain metastasis comparing resection followed by whole-brain radiotherapy (WBRT) to WBRT alone have shown a statistically significant survival advantage for surgery and WBRT. A multiinstitutional retrospective study was performed, which identified comparable patients who were treated with(More)
