Background: Glomus tumors are difficult to manage surgically because they are vascular tumors that are topographically associated with important vascular and neuronal structures. Hence, there is a strong risk of incomplete resection and a high morbidity rate. In addition, they grow slowly.

Purpose: To describe a technique of segmental radioembolization for the treatment of patients with unresectable hepatocellular carcinoma (HCC). Radiation segmentectomy was defined as radioembolization of two or fewer hepatic segments. We sought to (1) calculate dose when activity is delivered segmentally assuming uniform and nonuniform distribution and, (2) determine safety and efficacy of this novel technique.

Although anecdotal reports have suggested increased radiation dermatitis, the overall effect of these regimens on dermatologic toxicities has not been ascertained.
Methods: Dermatologic toxicity data were analyzed from abstracts presented at the annual meetings of the American Society of Clinical Oncology, the American Society of Therapeutic Radiology and Oncology, Cochrane Collaboration, MEDLINE, and EMBASE databases.
Purpose: To determine the radiation dose to the carotid artery in nasopharyngeal cancer patients treated with intensity-modulated radiotherapy (IMRT) and to compare it to the dose delivered by a conventional three-field (3F) technique.
Materials And Methods: Sixteen patients with nasopharyngeal cancer who were treated at UCSF with IMRT were selected for this analysis. 3F plans were reconstructed for comparison.
Purpose: We summarize our experience with a series of morbidly obese men treated using daily online portal imaging and implanted gold markers to guide external beam radiation therapy (EBRT).
Methods And Materials: Three consecutive morbidly obese men were treated with EBRT for localized prostate cancer. Daily electronic portal imaging was used to verify patient position.
