In intracavitary radiotherapy (ICRT) for cancer cervix, applicator geometry has the potential to impact the doses to organs at risk (OARs) and the coverage of the target volume. At our centre two Varian made Fletcher-style applicator sets, namely defined (fixed) geometry and flexible geometry, are used for ICRT. In the present work, the two types of applicators were compared dosimetrically as p...
PURPOSE To investigate the dosimetric results and first clinical experiences with a new designed balloon applicator with adjustable catheters for endoluminal brachytherapy for patients with locally advanced rectal cancer not undergoing surgery. MATERIAL AND METHODS The applicator consists of an inflatable rectal balloon with six attached Foley catheters used as guidance for the inserted brach...
BACKGROUND Optimal applicator insertion is a precondition for the success of cervix cancer brachytherapy (BT). We aimed to assess feasibility and efficacy of MRI-assisted pre-planning, based on applicator insertion in para-cervical anaesthesia (PCA). PATIENTS AND METHODS Five days prior to BT, the pre-planning procedure was performed in 18 cervix cancer patients: tandem-ring applicator was in...
Background: Surgical site infection (SSI) remains a concern in shoulder surgery, especially during arthroplasty. Whilemany studies have explored the characteristics and efficacy of different sterilizing solutions, no study has evaluated themethod of application. The purpose of this study was to compare two popular pre-surgical preparatory applications (two4 x 4 cm gauze sponges and applicator s...
PURPOSE To determine the optimal location of catheters in multichannel vaginal applicators to appropriately cover the vaginal cuff target and minimize dose to the organs at risk (OARs) and hot spots in the target. METHODS A new multichannel vaginal applicator with a diameter of 30 mmconsists of a single central catheter and an outer array of eight catheters. A total of 20 plans were generated...
