Trigeminal neuralgia is a paroxysmal pain syndrome commonly associated with multiple sclerosis. While gamma knife radiosurgery has been shown to be an effective treatment for most cases of trigeminal neuralgia, it considered less efficacious in patients sclerosis and viable as option.Seven multiple-sclerosis-associated were identified from 50 consecutive treated at the Memorial-Hermann Gamma Knife Radiosurgery Center. A Leksell was used deliver 80 or 90 Gy single 4-mm isocenter targeting...
Stereotactic radiosurgery (SRS) and fractionated stereotactic radiotherapy (FSRT) programs to treat brain tumors were implemented when we first acquired the Brainlab Novalis system in 2003. Two years later, started an extra-cranial radio-ablation or more appropriately a body radiation therapy (SBRT) program using image-guided at The Methodist Hospital Houston, Texas. We hereby summarize our initial experience with this delivering SBRT total of 80 patients during year clinical implementation,...
Intensity modulated radiation therapy (IMRT), a new form of three-dimensional conformal (3DCRT), optimizes the concept computer-controlled deposition in tumor (target) while sparing adjacent normal structures. A retrospective review was done on initial 185 patients with tumors different sites including prostate cancer, head and neck pediatric tumors, adult brain previously irradiated recurrent treated IMRT. Preliminary findings indicate that IMRT is clinically feasible tool oncology....
Breast adenomyoepithelioma (AME) is a rare tumor with the published literature mainly in form of case reports. Thus, there currently only limited data to guide evidence-based management. We sought use large, contemporary US database evaluate how these patients are managed and describe expected outcomes. The National Cancer Database was queried (2004-2013) for women AME. Statistics included multivariable logistic regression, Kaplan–Meier analysis overall survival (OS) Cox proportional hazards...
Intensity-modulated beam radiotherapy (IMRT) delivers a highly conformal, three-dimensional (3-D) distribution of radiation doses that is not possible with conventional methods. When administered to patients head and neck tumors, IMRT allows for the treatment multiple targets different doses, while simultaneously minimizing uninvolved critical structures such as parotid glands, optic chiasm, mandible. With 3-D computerized dose optimization, vast improvement over customary trial-and-error...
Develop a novel three-dimensional (3-D) anatomical model to assist in improving spatial knowledge of the skull base, paranasal sinuses, and adjacent structures, validate utilization 3-D reconstruction augment two-dimensional (2-D) computed tomography (CT) for training medical students otolaryngology-head neck surgery residents.Prospective study.A study 18 subjects studying sinus anatomy was conducted at tertiary academic center during 2011 2012 year. An image processing modeling program used...
Background Although randomized data support omitting adjuvant radiotherapy (RT) following breast conservation for T1-2N0 estrogen receptor positive cancer in ≥70-year-old women, there remains a knowledge gap regarding its omission triple-negative BC (TNBC). Methods and materials The National Cancer Database (NCDB) was queried females with newly diagnosed T1-2N0M0 TNBC treated conservation. Multivariable logistic regression ascertained factors associated RT administration. Overall survival...
