results histopathologically, a decrease (statistically not significant) in the thickening of alveolar or bronchial wall, formation of fibrous bands, and superimposed collagen were noted in the animals in group b as compared to the animals in group a. conclusion in this experimental study, administration of gla one hour before thoracic irradiation may be a protective agent against radiation-indu...

Introduction Radiotherapy with small fields is used widely in newly developed techniques. Additionally, dose calculation accuracy of treatment planning systems in small fields plays a crucial role in treatment outcome. In the present study, dose calculation accuracy of two commercial treatment planning systems was evaluated against Monte Carlo method. Materials and Methods Siemens Once or linea...

Background: Despite the benefits of contrast-enhanced computed tomography (CT) scans in better tumor volume delineation, it can affect accuracy dose calculation radiation therapy. This study examined this effect on a thorax phantom. Objectives: The influence different variables including concentrations Visipaque contrast media, sizes, and CT scan energies measurement was examined. Methods: Tran...

The purpose of this study is to describe the comprehensive commissioning process and initial clinical performance of the Vero linear accelerator, a new radiotherapy device recently installed at UT Southwestern Medical Center specifically developed for delivery of image-guided stereotactic ablative radiotherapy (SABR). The Vero system utilizes a ring gantry to integrate a beam delivery platform ...

Background: Small cell lung cancer (SCLC) represents 14% of all lung cancer cases. The current standard of care for limited stage SCLC is the chemotherapy combination of EP (etoposide, cisplatin) with concomitant radiotherapy. Treatment protocol is tolerated well and is associated with few side effects.Case Description: 58 y.o. lady diagnosed to have limited stage SCLC in our institute in Novem...

To assess the effectiveness of endovascular stenting for the palliation of superior vena cava (SVC) syndrome, endovascular stent insertion was attempted in 10 patients with symptomatic occlusion of the SVC. All the patients had known malignant disease of the thorax. Eight patients had been treated previously with chemotherapy and radiotherapy (n=5), chemotherapy alone (n=2), or pneumonectomy an...
