Context: Intraoperative radiotherapy (IORT) is an accepted standard treatment for early stages of breast cancer in the selected cases. This proven two large clinical trials including ELIOT and TARGIT-A ones, which are based on high energy electron beam low kV X-ray energy, respectively. Published results aimed at evaluating local recurrence as final outcome. In study, rate 4.4% versus 0.4% patients, who received IORT External Beam Radiotherapy (EBRT), comparison to 3.2% 1.3% trial. These...
Secondary cancer risk estimation following prostate radiotherapy through gEUD concept and NCRP-116 recommendations
Introduction Medulloblastoma is a central nerves tumor that often occurs in pediatrics. The main radiotherapy technique for this type craniospinal irradiation (CSI), through which the whole brain and spinal cord are exposed to radiation. Due immaturity of healthy organs pediatrics, radiogenic side effects such as second cancer more severe. Accordingly, current study aimed evaluate risk secondary development following CSI.
Abstract Background Safety is a mandatory issue during the operation of nuclear power plant. A reactor can have some atmospheric dispersion due to any errors in safety system. Purpose The aim this study estimate cancer risk incidence for different body organs accidentally released radionuclides from Bushehr Nuclear Power Plant (BNPP). Materials and methods assumed hypothesis was radionuclide into environment failure BNPP. Total effective dose equivalent (TEDE) diffusion medium calculated...
demonstrated in expanded cohorts, with prolonged life-long follow-up.
Abstract This study aimed to estimate the individual patient’s lung and breast dose using SSDE method as well effective in patients who underwent chest CT scans during COVID-19 pandemic. The cancer risk incidence was estimated excess relative (ERR), absolute (EAR), lifetime attributable (LAR) models of biological effects ionizing radiation report VII (BEIR-VII). information about 570 for screening used this study. Using header images a python script, were calculated each patient. obtained by...
Abstract Proton therapy and plaque-based brachytherapy are considered efficient radiotherapy modalities for intraocular tumor irradiation. The current study aims to measure compare the dosimetric features of these methods through a film dosimetry approach inside an eyeball phantom. A 3D-printed PLA (polylactic acid)-based phantom was applied For brachytherapy, COMS CGD plaques respectively containing 125 I 106 Ru radioactive sources were employed. irradiation performed using clinical...
Background and Objective: Avoiding the underlying healthy tissue over-exposure during breast intraoperative electron radiotherapy (IOERT) is owing to use of some dedicated radioprotection disks patient irradiation. The originated contaminant photons from widely used double-layered shielding including PMMA+Cu, PTFE+steel, Al+Pb configurations IOERT have been evaluated through a Monte Carlo (MC) simulation approach.Methods: Produced beam with energies 6, 8, 10, 12 MeV by validated MC model...
