Applicator Attenuation Effect on Dose Calculations of Esophageal High-Dose Rate Brachytherapy Using EDR2 Film
Introduction Interaluminal brachytherapy is one of the important methods of esophageal cancer treatment. The effect of applicator attenuation is not considered in dose calculation method released by AAPM-TG43. In this study, the effect of High-Dose Rate (HDR) brachytherapy esophageal applicator on dose distribution was surveyed in HDR brachytherapy. Materials and Methods A cylindrical PMMA phan...
متن کاملHigh-dose-rate intraluminal brachytherapy for paraneoplastic autoimmune multiorgan syndrome
Paraneoplastic autoimmune multiorgan syndrome (PAMS), also known as paraneoplasic pemphigus, involves the skin, internal organs and mucosa. PAMS-associated mortality may occur as a result of autoantibody formation against internal tumors and their infiltration into organs other than the skin lesions that characterize PAMS. The most common symptoms of PAMS include pain associated with continuous...
متن کاملHigh-dose-rate intraluminal brachytherapy prior to external radiochemotherapy in locally advanced esophageal cancer: preliminary results
PURPOSE Dysphagia is a common initial presentation in locally advanced esophageal cancer and negatively impacts patient quality of life and treatment compliance. To induce fast relief of dysphagia in patients with potentially operable esophageal cancer high-dose-rate (HDR) brachytherapy was applied prior to definitive radiochemotherapy. MATERIAL AND METHODS In this single arm phase II clinica...
متن کاملPalliative treatment by high-dose-rate intraluminal brachytherapy in patients with advanced esophageal cancer.
PURPOSE The aim of this work was to analyze the results of palliative HDR brachytherapy in patients with advanced esophageal cancer. METHODS AND MATERIALS Ninety-one patients with unresectable, advanced esophageal cancer were treated palliatively by HDR brachytherapy. All patients received a total dose of 22.5 Gy in three fractions per week. Remissions of dysphagia and other clinical and radi...
متن کاملGamma Dose Rate Measurement and Dose Rate Calculation for Sensitive Organs in the Vicinity of Hot Springs in Kerman Province
Introduction: All of the people worldwide are exposed to low levels of radiation. Cancer induction and genetic disorders are among the hazards of low level exposure. In some cases, radiation close to hot springs is higher than normal areas due to a high concentration and the decay products of Ra-226. Given the use of hot springs by the general public because of their therapeutic p...
