PURPOSE Radical cystectomy currently is the treatment of choice in muscle-invasive bladder cancer. However, cystectomy is associated with considerable morbidity. Bladder sparing treatment consists of transurethral resection of the tumor (with or without partial cystectomy), external beam radiotherapy, and brachytherapy. The purpose of this study is to compare bladder preservation with brachythe...

PURPOSE This multicenter, retrospective study evaluated treatment and clinical outcomes of patients with early stage breast cancer who received adjuvant high-dose rate (HDR) electronic brachytherapy (EBT) treatment post-lumpectomy using the Axxent(®) EBT system. Dosimetric data from the EBT treatment plans were compared with those based on iridium-192 HDR brachytherapy. MATERIAL AND METHODS M...

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...

In this work, we report a comprehensive quality assurance (QA) process for the commissioning of an Electronic Brachytherapy (EB) system at one of the first U.S. sites to apply the device clinically. Thus far, EB systems have been released only for intracavitary breast treatments. As such, EB as an Accelerated Partial Breast Irradiation (APBI) treatment modality is relatively unstudied and is un...

In this study, we evaluate the attenuation of the dose due to barium-impregnation in the region between the surface of an electronic brachytherapy (EBT) balloon applicator for accelerated partial breast irradiation (APBI) and the prescription point at 1 cm depth in tissue. To perform the study, depth dose curves were calculated using a general purpose multi-particle transport code (FLUKA) for a...

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...

We have read with an interest the article of Olga Pons-Llanas et al. [1] published in the Journal about the use of electronic brachytherapy (EBT) in non-melanoma skin cancer (NMSC). However, we noticed the exclusion criteria for the following tumors: lesions with a diameter greater than 20 mm, invasion of more than 4 mm, irregular anatomic areas. Besides, there are limits linked to the use of c...

The second part of the GYN GEC ESTRO working group recommendations is focused on 3D dose-volume parameters for brachytherapy of cervical carcinoma. Methods and parameters have been developed and validated from dosimetric, imaging and clinical experience from different institutions (University of Vienna, IGR Paris, University of Leuven). Cumulative dose volume histograms (DVH) are recommended fo...

PURPOSE The use of radiation therapy (RT) for non-melanoma skin cancer (NMSC) has been changing throughout the last century. Over the last decades, the use of radiotherapy has surged with the development of new techniques, applicators, and devices. In recent years, electronic brachytherapy (eBT) devices that use small x-ray sources have been introduced as alternative to radionuclide dependence....

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...
