Rapid Multi-Site Remote Surface Dosimetry for Total Skin Electron Therapy: Scintillator Target Imaging. The goal of this work is to produce a surface-dosimetry method capable of accurately and remotely measuring skin dose for patients undergoing total skin electron therapy (TSET) without the need for postexposure dosimeter processing. A rapid and wireless surface-dosimetry system was developed

Radiobiological Evaluation of Three Common Clinical Radiotherapy Techniques Including Combined Photon-Electron, Tangential Beams and Electron Therapy in Left-Sided Mastectomy Patients The aim of this study was radiobiological evaluation of different radiotherapy (RT) techniques, namely, combined photon-electron, two tangential photon beams, and electron therapy which are commonly used to tangential beams (up to 11%, 11%, 5%, and 5%, respectively) and the electron therapy (up to 11%, 11%, 33%, and 23%, respectively) Whereas the NTCPs of the tangential beams for ipsilateral and contralateral lungs, heart, and chest wall-lung interface was 4%, 1%, 3%, and 5.6%, respectively. These NTCP values were considerably lower than electron therapy (up to 42%, 66%, and 40% and 30%, respectively

A technique for total skin electron therapy (TSET) of an anesthetized pediatric patient Total skin electron therapy (TSET) is a technique to treat cutaneous lymphomas. While TSET is rarely required in pediatric patients, it poses particular problems for the delivery. It was the aim of the present work to develop a method to deliver TSET to young children requiring anesthetics during treatment to skin was verified daily using thermoluminescence dosimetry and/or radiochromic film. The treatment parameters were adjusted slightly based on in vivo dosimetry resulting in a dose distribution for most of the treatment volume within ±20% of the prescribed dose. Six areas were boosted using conventional electron therapy. TSET can be delivered to pediatric patients using a customized couch top

Long-Term Results of a Highly Performing Conformal Electron Therapy Technique for Chest Wall Irradiation After Mastectomy. To evaluate locoregional control and survival after mastectomy, as well as toxicity, in patients irradiated by a previously described postmastectomy highly conformal electron beam radiation therapy technique (PMERT). We included all women irradiated by postmastectomy

Chemoradiotherapy with Brachytherapy or Electron Therapy Boost for Locally Advanced Squamous Cell Carcinoma of the Anus—Reducing the Colostomy Rate The aim of this study is to determine overall survival, disease-specific survival and stoma-free survival after treatment of squamous cell carcinoma of the anus with chemoradiotherapy followed by brachytherapy or electron boost in a recent cohort

Highly Effective Auger-Electron Therapy in an Orthotopic Glioblastoma Xenograft Model using Convection-Enhanced Delivery Glioblastoma, the most common and malignant primary brain tumor, always recurs after standard treatment. Therefore, promising new therapeutic approaches are needed. Short-range Auger-electron-emitters carry the ability of causing highly damaging radiation effects in cells

Utilization of a 3D printer to fabricate boluses used for electron therapy of skin lesions of the eye canthi This work describes the use of 3D printing technology to create individualized boluses for patients treated with electron beam therapy for skin lesions of the eye canthi. It aimed to demonstrate the effectiveness of 3D-printed over manually fabricated paraffin boluses. The study involved

Total Skin Electron Therapy for Cutaneous T-Cell Lymphoma Using a Modern Dual-Field Rotational Technique. To report our experience with rotational total skin electron irradiation (RTSEI) in cutaneous T-cell lymphoma (CTCL), and to examine response by disease stage and race. We reviewed our outcomes for 68 CTCL patients who received RTSEI (≥ 30 Gy) from 2000 to 2013. Primary outcomes were

Combined Beta- Plus Auger Electron Therapy Using a Novel Somatostatin Receptor Subtype 2 Antagonist Labelled With Terbium-161 (161Tb-DOTA-LM3) The goal of this phase 0 proof-of concept study is to measure the therapeutic index (tumour to dose-limiting-organ dose ratios) of 161Tb-DOTA-LM3 in comparison to the current standard 177Lu-DOTATOC in the same gastroenteropancreatic neuroendocrine tumour

production, recovery of BaCO target material, and fundamental imaging characteristics superior to those of Ga and La, La represents a promising radiometal candidate to provide high-resolution PET imaging as a PET/α-therapy theranostic pair with Ac or as a PET/Auger electron therapy theranostic pair with La.

Convolution‐based modified Clarkson integration (CMCI) for electron cutout factor calculation Electron therapy is widely used to treat shallow tumors because of its characteristic sharp dose fall-off beyond a certain range. A customized cutout is typically applied to block radiation to normal tissues. Determining the final monitor unit (MU) for electron treatment requires an output factor to -9.28% deviations from the measurement for 6E beam. At extended SSD, the mean absolute errors of our method relative to measurements were 0.92 and 1.14, while the errors of eMC were 1.42 and 1.79 for SSD 105 cm and 110 cm, respectively. These results indicate that our method is more accurate than eMC, especially for low-energy beams, and can be used for MU calculation and as a QA tool for electron

times per week for varying lengths of time; 4 patients received a total dose of 60 Gy, 1 received 48 Gy and the 4 remaining patients received 45 Gy. The patient who received 48 Gy also underwent additional electron therapy of 16 Gy in 8 fractions. The overall survival, progression-free survival and local progression-free rates at 3 years were 50.8% [95% confidence interval (CI): 15.6-78.1%], 37.0% (95

excellent agreement with CT obtained surfaces. Using 3D surface imaging instead of x-ray based CT, benefits include: no ionizing radiation used to produce images, shorter time between patient consultation and treatment, and ability to produce and evaluate patient-specific devices for electron therapy earlier in the treatment planning process. This study may help researchers learn how 3D surface scanning

Several different radiotherapy techniques and fractionation schedules were performed in the analysis, including high-dose rate (HDR) irradiation with Ir at 8 Gy/1 fraction (F)+9 Gy/3F or 20 Gy/4F; HDR brachytherapy with Co at 20 Gy/4F or 18 Gy/6F; or external beam electron therapy at 26 Gy/13F or 30 Gy/15F. The endpoints of the study
