cavernous hemangioma is a rare benign tumor of the internal auditory canal (iac) of which fourteen cases have been reported so far. tinnitus and progressive sensorineural hearing loss (snhl) are the chief complaints of the patients. audiological and radiological planes, ctscan, and magnetic resonance image (mri) studies are helpful in diagnosis. the only choice of treatment is surgery with elec...

Objective(s): In this study, the effects of different doses of curcumin application on Ehrlich ascites tumor (EAT) created in the mice of BALB/c type were investigated.Materials and Methods: Curcumin extracts can have hindering effect on tumor volume, vascular density, EAT cells around the tissues, and can support apoptosis. EAT cells (1x106) received from stock animals were injected intraperit...

The purpose of this study was to compare the dose-volume statistics of stereotactic body radiotherapy (SBRT) for lung cancer between planning target volume (PTV): D95 and gross tumor volume (GTV): D99 dose prescriptions using Monte Carlo (MC) calculation. Plans for 183 patients treated between October 2010 and April 2013 were generated based on four-dimensional (4D) computed tomography (CT) und...

Patients with neurofibromatosis 1 (NF1), NF2, and schwannomatosis share a predisposition to develop multiple nerve sheath tumors. Previous studies have demonstrated that patients with NF1 and NF2 have reduced quality of life (QOL), but no studies have examined the relationship between whole-body tumor burden and QOL in these patients. We administered a QOL questionnaire (the SF-36) and a visual...

We propose a clinical workflow of stereotactic volumetric modulated arc therapy (VMAT) for a lung tumor from planning to tumor position verification using 4D planning computed tomography (CT) and 4D cone-beam CT (CBCT). A 4D CT scanner, an Anzai belt and a BodyFix were employed to obtain 10-phase respiratory-correlated CT data for a lung patient under constrained breathing conditions. A plannin...

Respiratory motion causes uncertainties in tumor edges on either computed tomography (CT) or positron emission tomography (PET) images and causes misalignment when registering PET and CT images. This phenomenon may cause radiation oncologists to delineate tumor volume inaccurately in radiotherapy treatment planning. The purpose of this study was to analyze radiology applications using interpola...

the antitumor activity of ethanol extract of prosopis glandulosa torr. (epg) was evaluated against ehrlich ascites carcinoma (eac) tumor model in swiss albino mice on dose dependent manner. the activity was assessed using survival time, average increase in body weight, hematological parameters and solid tumor volume. oral administration of epg at the dose of 100, 200 and 400 mg/kg, significantl...

Despite the well-known benefits of positron emission tomography (PET) imaging in lung cancer diagnosis and staging, the poor spatial resolution of PET has limited its use in radiotherapy planning. Methods used for segmenting tumor from normal tissue, such as threshold boundaries using a fraction of the standardized uptake value (SUV), are subject to uncertainties. The issue of respiratory motio...

conclusions our data showed that the amount of hydration, transfusion, pre-manipulation arrhythmia, and pulmonary function should be controlled to decrease the risk of arrhythmias. minor mediastinal manipulation, few intraoperative hemorrhages, improvement of pulmonary function, and careful blood pressure monitoring can reduce the risk of hypotension. patients and methods in this prospective st...
