On the other hand, brachytherapy combined with external beam irradiation is not a good therapeutic approach in advanced disease because, in this case, the brachytherapy target volume would be by definition identical for a primary brachytherapy and/or for a brachytherapy boost. (8,11) For any tumour size, the combination of external beam irradiation and brachytherapy boost yields worse results t...

The American Brachytherapy Society (ABS) and its membership seeks to benefit patients by promoting the highest possible standard for brachytherapy practice, support health care professionals through the encouragement of state of the art technology and education, promote clinical and laboratory research, and advocate for the socioeconomic aspects of brachytherapy. The 2017 ABS Annual Meeting too...

acute aortic dissection (aad) is the most frequent catastrophic event of the aorta; it occurs nearly three times as frequently as the rupture of abdominal aortic aneurysm . sixty percent of dissection cases are classified as proximal or type a and 40% as distal or type b, according to the stanford classification. the most frequent causes of death in acute type b dissection are aortic rupture an...

Partial breast irradiation (PBI) by either brachytherapy or external beam (EB) therapy is frequently used for the treatment of certain populations of breast cancer patients. The claim that brachytherapy is better than EB for PBI is the Proposition debated here. Advantages claimed for brachytherapy for PBI include: • brachytherapy is associated with smaller treatment volumes, lower integral dose...

SCIENTIFIC BACKGROUND Percutaneous transluminal angioplasties (PTA) through balloon dilatation with or without stenting, i.e. vessel expansion through balloons with or without of implantation of small tubes, called stents, are used in the treatment of peripheral artery occlusive disease (PAOD). The intravascular vessel irradiation, called intravascular brachytherapy, promises a reduction in the...

Introduction In this study, we aimed to calculate dose enhancement factor (DEF) for gold (Au) and iron (Fe) nanoparticles (NPs) in brachytherapy and teletherapy, using Monte Carlo (MC) method. Materials and Methods In this study, a new algorithm was introduced to calculate dose enhancement by AuNPs and FeNPs for Iridium-192 (Ir-192) brachytherapy and Cobalt-60 (Co-60) teletherapy sources, using...

Introduction: Brachytherapy is one type of internal radiation therapy where radiation sources, which are usually encapsulated, are placed as close as possible to the tumor site or inside the patient's body. In this technique, it is important to determine dose distribution around the brachytherapy capsule to create optimal treatment plant. In this way, dosimetric parameters are...

Traditional brachytherapy refers to the placement of radioactive sources on or inside the cancer tissues. Based on the type of sources, brachytherapy can be classified as radionuclide and electronic brachytherapy. Electronic brachytherapy uses miniaturized X-ray sources instead of radionuclides to deliver high doses of radiation. The advantages of electronic brachytherapy include low dose to or...
