We evaluated the productions of an artist with frontotemporal lobar degeneration from before dementia onset until she was fully symptomatic. We noted an improvement of technique that might be related to sparing and disinhibition of the right posterior neocortex. There was a reduction of closure (completeness of the painting), possibly induced by(More)
Several advances in large data set collection and processing have the potential to provide a wave of new insights and improvements in the use of radiation therapy for cancer treatment. The era of electronic health records, genomics, and improving information technology resources creates the opportunity to leverage these developments to create a learning(More)
In radiotherapy, only a few immobilization systems, such as open-face mask and head mold with a bite plate, are available for claustrophobic patients with a certain degree of discomfort. The purpose of this study was to develop a remote-controlled and self-contained audiovisual (AV)-aided interactive system with the iPad mini with Retina display for(More)
The safety and efficacy of stereotactic radiosurgery (SRS) in the brainstem is questioned by some over concern of violating historical brainstem SRS dose tolerance. Our purpose was to report on the clinical outcomes of patients treated at our institution with radiosurgery for brainstem metastases. Patients with metastatic tumors within or directly abutting(More)
OBJECTIVE Although brainstem metastases are thought to portend an inferior prognosis compared to non-brainstem brain metastases, there is limited evidence to support this claim, particularly in the modern radiosurgical era. METHODS We collected the clinical data for 500 patients with brain metastases treated at our institution with stereotactic(More)
Brain metastases from gastrointestinal (GI) primary malignancies are generally less common than those arising from other primary locations. Our purpose was to analyze the efficacy of stereotactic radiosurgery (SRS) in the treatment of patients with brain metastases from GI malignancies in the modern radiosurgical and systemic therapy era. A review of(More)
PURPOSE Although the use of stereotactic radiosurgery (SRS) in the treatment of multiple brain metastases has increased dramatically during the past decade to avoid the neurocognitive dysfunction induced by whole brain radiation therapy (WBRT), the cumulative neurocognitive effect of numerous SRS sessions remains unknown. Because leukoencephalopathy is a(More)
PURPOSE To pool data across multiple institutions internationally and report on the cumulative experience of brainstem stereotactic radiosurgery (SRS). METHODS AND MATERIALS Data on patients with brainstem metastases treated with SRS were collected through the International Gamma Knife Research Foundation. Clinical, radiographic, and dosimetric(More)
Intraoperative radiation therapy (IORT) is a method of accelerated partial breast irradiation developed to replace other longer courses of radiotherapy with a single radiation session administered at the time of breast-conserving surgery. The purpose of this review is to summarize the advantages and disadvantages of breast IORT techniques that are currently(More)
PURPOSE This study reports the outcomes of adults with soft tissue sarcoma (STS) of the head and neck following resection and postoperative radiotherapy (RT), and provides a framework for explaining the issues that radiation oncologists must understand to manage patients with this diverse group of tumors. METHODS AND MATERIALS Twenty-four patients met the(More)
