Consideration of accurate dose distribution for Contura balloon catheter in breast brachytherapy with MCNP5 simulation
Introduction: Contura is a balloon applicator that used to deliver intra cavity radiation for Partial Breast Irradiation (PBI) treatments. Contura with 4 peripheral lumens surrounding the central, for loading HDR sources from an after loader system can provide an asymmetric dose distribution and gives a more flexible shape of dose than earlier balloon applicators such as Mammo...
متن کاملDosimetric Improvements in Balloon Based Brachytherapy Using the Contura® Multi-Lumen Balloon (MLB) Catheter to Deliver Accelerated Partial Breast Irradiation
PURPOSE Preliminary dosimetric findings in patients managed with the Contura® Multi-Lumen Balloon (MLB) breast brachytherapy catheter to deliver accelerated partial breast irradiation (APBI) on a multi-institutional phase IV registry trial were reviewed. MATERIAL AND METHODS CT-based 3D planning with dose optimization was performed for all patients. For the study, new ideal dosimetric goals w...
متن کاملSkin and chest wall dose with multi-catheter and MammoSite breast brachytherapy: Implications for late toxicity.
PURPOSE Accelerated partial breast irradiation (APBI) continues to increase in popularity. Up to 14% of patients treated with the MammoSite (MS) report some degree of chronic pain, which may be related to chest wall toxicity. Reports from several institutions using the multicatheter (MC) technique have not shown associated elevated chest wall toxicity. Additionally, a recent investigation has s...
متن کاملComparison of single and multiple dwell position methods in MammoSite high dose rate (HDR) brachytherapy planning
The purpose of this study is to dosimetrically compare two plans generated using single dwell position method (SDPM) and multiple dwell position methods (MDPM) in MammoSite high dose rate (HDR) brachytherapy planning for 19 breast cancer patients. In computed tomography (CT) image-based HDR planning, a surface optimization technique was used in both methods. Following dosimetric parameters were...
متن کاملDose modification factor analysis of multilumen balloon brachytherapy applicator with Monte Carlo simulation
The Contura brachytherapy applicator is a silicone balloon with five lumens in which a high-dose-rate brachytherapy source can traverse. Multilumen applicators, like the Contura, are used in accelerated partial breast irradiation (APBI) brachytherapy in instances where asymmetric dose distributions are desired; for example, when the applicator surface-to-skin thickness is small (< 7 mm). In the...
